Haze-Ebi (Goby-Shrimp) Symbiotic Relationship

 

Some of the harder species to record in Maizuru. 

Itohikihaze イトヒキハゼ is a common species of goby found near the lab but is extremely skittish. They often dart back into their burrows when approached. These burrows are dug by the blind pistol shrimp that they protect forming a symbiotic relationship (Karplus&Thompson 2011). I really had to approach them slowly in order to get my camera close enough (which isn't always easy underwater). Then of course remain still so the shrimp also relaxed enough to come out and continue its burrow maintenance. 

This species did a couple interesting behaviors of interspecific communication. First, the tail flicking of the gobies is understood to be a warning signal to the shrimp as there is potential danger in the area and sometimes indicate necessary retreat back into the burrow. The shrimp noticed this because it uses its antennae to always keep a tactile connection to the goby while outside of the burrow. However, a clear signal for retreat is when the gobv dives back into the burrow head-first (Karplus&Tuvia1979).  

What was interesting was that the goby did show some rapid color changes while outside the nest. Since the shrimp are blind, I wonder the purpose of this. You can see it happen at 2:04. There's a lot of theories about the meaning of color changes but it is still largely a mystery. 

Anyways, I hope y'all enjoy this one.

To those that have joined me on adventure


    I want to take a quick minute (or minute 40) to thank all those who have joined me on my adventures over the years. I have been diving for 8 years now and it hasn't even felt close to that. I've gotten the pleasure of diving with so many amazing people over the years and have made lifelong friends doing what I love. Nothing really compares to it. 

    So, thanks to all of you who have followed me into the abyss, crazy cliffs, camping in remote areas, and indulging my adrenaline addiction. Sometimes it was for fun, others were for projects, but all were memorable. I've recently logged my 300th dive and I have journal entries describing each one and who I've dove with. Can honestly say its over 100 people, so there are many left out of this little edit. This is just some B-roll footage of all these crazy adventures over the years. 

    I also wanted to use a song I have been listening to on repeat. Listening to John Frusciante is like listening to a phoenix. Someone who was great before the fall but needed to crash and burn hard before he really rose up to become amazing. This song was from his darkest time in the mid 90s and features his late friend River Phoenix. A beautiful song that helped me through a dark time a while ago. I only wish we could have heard more.

Pederson's Shrimp (Ancylomenes pedersoni) Cleaning Dance

 


 

Sometimes there are unusual behaviors that you don't notice until you read about them. My friend Shoju Shi introduced a paper about this little shrimp, Pederson's Shrimp (Ancylomenes pedersoni) and the dances they do to indicate to reef fish that they are willing to clean. This then pairs with the reef fish color changing to a darker tone to indicate to the shrimp it is ready to be cleaned.

Back in 2017 when I took a trip to Belize, I had recorded this little fella while on a dive around the Blue Hole, specifically near a reef called The Aquarium Wall. It was insanely clear but I had unfortunately broke my deep water filters. This was the last dive of the day but the water was warm and there was still so much to see. Out of the corner of my eye, I notice this small shrimp near an anemone swaying back and forth. The current didn't seem to be that strong so I took a quick recording and moved along.

Knowing what I know now, this was actually a pretty cool behavior. The shrimp typically does the tail wagging and antennae whipping as its signal to fish it wishes to clean. I had gotten up close to this little bugger so he probably was offering a clean. I should have taken out my reg and opened my mouth for a little tonsil cleaning.

Echizen Dives

 

Just a quick edit but I loved this one. Rough surf to get pass and a swell that was surging even at 20 meters. Still though, different than anywhere else I've been diving in Japan. 

There was a tropical species that made its way this far north to Japan that was interesting to see. Sorasuzumedai ソラスズメダイ is a vibrant blue/yellow species that drifts up from the tropics and settles while the water is warm here. In winter however, the fish disappear until the next late summer when newly drifted ones settle and start to grow. 

In a rapidly warming ocean, many of these tropical species are being seen more frequent in these temperate waters. Full effects are unknown but it is undeniable there is a shift in the ecosystems because of this. 

Hopefully there is a change.

Nagahama Dives

 

Just some pretty shots from my dives off of Nagahama in Maizuru. This is the area located right off of the lab so there are many experiments in the water. It can be murky at times but I think it just promotes a unique habitat not normally seen by vacation divers.

Man do I have an insane amount of footage now. Still running into the perfection roadblock of not wanting to use stuff out of focus or shaky so here's another video that came in a burst of inspiration. Kinda wish I could get back to those carefree roots. I remember shooting and editing a diving video within a day and it was the most fun thing ever. Maybe I can tap into that sometime. In any-case here ya go. Hope ya enjoy it.

Urchin Survey Dives - Tai and Obase in Maizuru


Recently I was asked to help out with some survey dives for a prominent company - Ocean Trading Co. We did many dives over two days (9 total dives) and I finally got to see some species that I have been searching for. Probably the most exciting was the Abalone (Awabi) and getting to dive on fabricated Abalone Artificial reefs. It really was a real treat and I hope to work with this company on more projects in the future. 

They want to pursue new ideas and fishing practices that benefit the environment the same way it benefits the market. This project aims to take urchins from densely populated barrens and culture them to market value and sell commercially. It is known urchin removal is the key to restoring diverse algal habitats so this project would not only benefit the urchin sellers but the underwater environment as well.

Abalone Artificial Reefs

 








Extra image of some Mackerel (Aji) egg tows in Maizuru Bay


I recently had an amazing opportunity to dive with my professor for some urchin surveys we were contracted to perform along the Wakasa bay coast. One of these sites happen to be an old abalone recruitment artificial reef. I had noticed some live abalone on some natural reefs nearby so there was likely some spillover effect. The actual ARs here were perfect squares about 2 meters across with about a half a meter height and a half a meter square taken out of the middle. There were plenty of fish along this reef, namely rockfish and wrasses, but I only found evidence of one abalone shell while diving here. This puzzled me until I asked the fishermen and my professor and they said in these summer months the abalone hide deeper below the reef and come out to feed more often in other months of the year. I really hope to return to this site when the abalone are more out in the open. I am also searching for any fisheries data that had been kept regarding this reef to see how well it has performed over the years. Its assume the grooves in each reef are cut to allow abalone recruits and juveniles a safe space to grow and then venture deeper into the reef. 

All in all I was extremely happy to have been able to make my first dive on a Japanese artificial reef. One designed specifically for abalone nonetheless. I also included an extra image of some mackerel egg tows done a couple weeks ago that I helped with by pulling the net up. Its really great to be helping out with so many projects.

Wakasa Bay Naturalist Club presentation - Kelp Forests and the Urchin Barren dilemma.

 

PC: Yamaguchi-san

Last week I gave a talk to a local naturalist group about the Kelp Forest. The Wakasa Bay Naturalist Club, invited myself as well as Chika and Reiji to give an educational talk about marine ecosystems. Since I had a lot of experience (as well as 100s of photos) with the kelp forest, they asked me to speak to its ecology and the growing Urchin Barren problem. This talk was live translated by my labmate Shoju. 

It was truly an honor to speak. I particularly enjoyed putting the presentation together and answering some poignant questions. It felt good to engage the local community. It felt reminiscent of the science pubs I went to in Santa Barbara. Of course there was a much more focused crowd that all had a keen interest in the subject. I really felt like I was sharing a unique, new experience with this community. This is probably one of my favorite aspects of my fledgling career.

I use to dread the presentation aspect, but I have since learned it was due to piss poor preparation. Obviously I was nervous when I wasn't prepared and wasn't confident in my delivery. Now its about having the discipline to practice and to remain calm while presenting on such topics. The lab itself has helped me with this, as they have us do various presentations throughout the semester. A life skill I am thankful to have, but yet to full master. 

Bring it on.

Golden Fireworm (Chloeia flava) consumes Injured Anchovy (Engraulis japonicus)

 

You never know what to expect underwater.

 I caught this interaction while on a routine dive survey off the lab in Maizuru. These worms are pretty ubiquitous and I normally see them roaming around the bottom. Today we had a shoal of anchovies come through and I noticed a few while on the dive. This one was probably injured from an encounter with another large animal and was stuck in the algae dying. Out of the corner of my eye, I notice a fireworm quickly coming its direction so I started to record.

Heres an exert from what is known about the species and its feeding behavior.

"Glasby & Bailey-Brock (2001) caught reef amphinomids by hook and line on carrion. Pardo & Amaral (2006) observed rapid chemotaxis of Eurythoe complanata to pieces of fish offered in aquaria. Detection of prey solutes elicited raising of the anterior 1/3 of the body, opening of the mouth and pharyngeal eversion. In the field, this posture would allow longer-range detection and easier determination of current direction in a bottom boundary layer. When worms reached the fish, the lower lip was sealed around it, and the muscular pharynx was used as a pump to draw the whole fish fragment in. Glasby & Bailey-Brock (2001) compiled evidence of carrion feeding in the form of capture on fishhooks and hand feeding in aquaria for Chloeia flava, Eurythoe complanata, Hermodice carunculata and Pherecardia striata."

First Dive in Japan


First of many dives in my new home for the next couple of years. Thanks for being patient and waiting for this video. 

Otomi - Fukui Prefecture- Japan 

This was my first time scuba diving in japan and I couldn't be happier. All new species to learn and a whole new language to learn them in. I may switch back to English common names in the future but for now I want to call them by by what they are locally known as.

I might get more opportunities to share the videos I will take during my dives. I may make more since I will be diving with a camera a lot or not since graduate school is challenging, who knows. Here's some pretty fish.

Alright here it is! The update you've all been waiting for. I FINALLY made it to Japan after 2 years of emails, nerve-racking applications, and a closed border limbo where I gained more weight than I care to share. It has been a fever dream the past week or so I have been here. I have little grasp of the language, extreme nervousness about new customs, and a google translate that's shotty at best. Thankfully, I have had incredible support along the way. It started even before I left the airport where I met Alex, a true godsend. He help we rescheduale my flight as the quarintine procedure made me miss my connection to Kansai Airport. After a shit ton of jetlag we make it on the trains from Kansai and I'm mezmerized by the landscape. Cherry blossoms are in full bloom here and it couldn't be more beautiful. Osaka and Kyoto were spralling cityscapes with such interesting acitecture and city planning, all vivible from the trains. I hope to go back and visit for longer in the future. Alex and I part ways in Kyoto and I take the bullet train (>150mph) up to Maizuru. I'm greeted by Reiji right there at the train station and immediately get welcomed into the fold at the labratory. It has been a huge rush to get paperwork in order and other buerocratic mess out of the way but I am finally starting to feel settled in. I have even gone out to stores and resurants by myself and easily ordered food, groceries, and found hard drive repair kits. A big FUCK YOU to American TSA who rummaged through my luggage and broke my one of my hard drives by not placing it back in the padded box I had it in.

I want to take this last little part to say Thank You to everyone who wished me well on this jouney back in the US and a thank you to everyone who is currently help me feel welcomed here in Maizuru. I can already tell I am going to love it here. I really couldnt have had the courage to do this without all the encouragement I have recieved on both ends of the flat disk we live on (theres an ice wall I swear). I hope to provide even more Japanese marine life in future updates... but for now, I'm gonna toast to all of you.

乾杯
Kanpai!

Hopkin's Rose (Okenia rosacea) Nudibranch

 

A beautiful Hopkin's Rose Nudibranch (Okenia rosacea) shot near Pescadero California during the king tides. Simply a stunning little nudi, I was lucky to have had this little guy pointed out to me by other tidepoolers. I may not be an expert on nudibranchs but I included a few names of the different body parts you can see in this close up shot. Enjoy.

Sarcastic Fringehead (Neoclinus blanchardi) Interactions - Unusual behavior


Some recent recordings of Sarcastic Fringehead (Neoclinus blanchardi) that I found unusual. The structures these guys are in are the artificial reefs installed on the sea bead to house predators and promote kelp growth along the sand. The depth was about 41'. I normally don't see them venturing outside of their safe hovels. It is hard to say what kind of behavior this is. This requires a bit more recordings and more regular monitoring of these fringehead, in addition to determining the sexes of these individuals. Of the times I've dove the site, I've only seen one fringehead swimming between hovels during a dive. I'd also normally see 1-3 fringehead per dive in these artificial reefs, with the rest of the structures occupied by two-spot octopus.

Southern California Oil Rig Diving

 

 

A recent dive with my good buddy mason off some Southern California Oil Rigs. Fish were huge on this structure. It was like flying through a large jungle gym. Probably one of my all time favorite dives. Most of our time was spent at 50-80 ft and it was incredibly dark throughout. the rigs themselves were working ones so the loud underwater sounds create an interesting situation for the life growing on them. What kind of effects would these constant loud sounds have on marine life. In any case these rigs were thriving with marine life and I highly recommend diving it if ever a chance.

My time during Quarantine


 

Pre-Covid
Almost 16 months in
  
Finally cut the rona mullet
 

Here comes a personal post. This one is for me. I really don't care if it comes off as gloating because this is my blog and I'm pretty sure I'm the only one who looks at it.

Covid became a serious inflection point in my life. I had ambitions and stuff going on but I was reluctant to set my sights higher and actually apply myself. In no other time in my life did I have a drive like I did when I saw this time as a time to improve.

 I started Covid learning that I had two job interviews that went sour. I didn't prepare for them at all and felt like I had squandered a serious opportunity. These weren't dream jobs but ones that would move me along my chosen career path. I stewed over this missed chance for a while... but the first lockdown came a knocking and I quickly saw this as a blessing. The jobs were diving jobs and with the pandemic I wouldn't have dove or really worked on more important endeavors anyways. Quarantine started to kick in and I saw myself falling into bad habits. Wake up, smoke, work, smoke, play video games, smoke, repeat. I was pretty depressed. I saw how this country let me down with so many peoples flagrant attitude toward the whole pandemic. I knew I needed serious change and by the end of this contagion I was going to be better.

I was consigned to an uncomfortable retail job that only got worse with the pandemic. Customers were rude, management was apathetic at best, and childish drama made working life a bit of a nightmare. I dreaded going into work. There quickly became a situation that only confirmed a long held belief I had. I'm keeping things vague but, in essence, I was given an opportunity to take 2 weeks off and use that time to find something better.

I was persistent and looked everywhere. I was about to do anything to get out of my current situation. Luckily I was given a wonderful opportunity with way better pay to work with an old friend of mine, Troy White, and I jumped on it. I was told I would be given 10-20 hours but was encouraged to work more. I did 40 almost every week because I had never been made such a living in my life. My work was good and I asked for constant feedback, asked questions I would normally be too timid to ask, and picked up new skills that helped me with the next huge stage in my life. I was quickly made a full time staff member (officially) and was promoted not long after. This was the first job that valued my skills, input, and work ethic and rewarded me for it. I really saw what working for a great boss looked like.

During this time I still remained loyal to my marine science passion projects. My paper was still in review and there simply wasn't anything I could do to expedite it on my front. I began researching for the sake of learning new things. I took an R coding class to attempt to build my computer skills. I asked mentors for reading material and came back with questions. I asked for more work. I filled up my time and to this day I pretty busy but I'm managing to keep it together. 

I finally saw a real chance. I came across a recent paper about artificial reefs. It was from Japan and the author had just finished his study there. I contacted the author of this paper who kindly answered my questions and then referred me to his advisor in Japan. After a bit of email tag and a couple contacted professors later, I was talking to Professor Reiji Masuda from Kyoto University. Reiji and I hit it off (at least I felt it on my end) and stayed in constant contact until I asked the question about graduate school. I had been contemplating graduate school for a while as I had learned how fulfilling it was to write my first paper. Reiji graciously invited me to join his lab in Maizuru, Japan.

By now I was star struck, giddy, and had this motivation I had not had for anything else in my life until this point. I didn't just want to get in... I NEEDED to get in. I made sure to keep in touch with Reiji and even put myself out there to other lab people. I asked for reading materials and learned of the awesome new technology surrounding environmental DNA and its possible applications. After a while graduate school applications started opening up. I was already well prepared but it was crunch time. I spent most of my free time and even put off sleeping some nights until I knew I could be confident in my application. January came around and just before finalizing my application I was given a task by my professor to help another student with the English in her paper. I made the time to review it and turn it around quickly, but thoroughly, reviewed. It was around this time I had also learned that my own paper had been published and I was finally being recognized for my hard work in marine science.

About a month later, and a few strong drinks to settle my nerves, I received the news. 

I... was... accepted!

I was going to be leaving California to live somewhere I had never been. I had done this before moving to Santa Cruz for my undergraduate degree but never really felt like I had left. This will be a total leap of faith but hey... what is life without some risk? 

I'm going to take what I learned in Covid and become the best damn researcher for myself. I going to research what interests me and it may not all be recognized in the way I want it... but I know I will enjoy it and my support network of friends, family, and mentors will too. If Covid has taught me anything is that you can take a shitty situation and flip it on itself. I can safely say I thrived during this time and will be heading off into the wild blue yonder come September. Thank you to everyone who supported me and here's a couple photos of the gross ass long hair I grew cause Great Clips or Super Cuts or whatever went out of business locally and I decided "ehh... fuckit" and let it go long. 

So anyways, cheers to the future and may it be as gracious to you as it has been for me. 

A year ago today I was at one of the lowest points in my life.... Quarantine

Now... Things couldn't be better.

Diving under Stern's Wharf, Santa Barbara

 

Some recent dives under Stern's wharf in Santa Barbara during the rona. We are now going into shutdown round 2. 

 I've been slacking on the videos, I really have. I'm just not as inspired as I use to be. Current events aside, this year has been too rollercoaster and too uncertain, I believe I'm burnt out.
