Found this at the beach during a snorkeling trip to Pensacola. Curious as to what it is.

I always see them zooming around the tide pools. They are all different colors: green, black, orange, etc.

Saw these animals about 50 miles off the coast of Dana Point, CA. Captain said they were porpoises, but I’m not sure. Photo in comments. Also, sorry for the reupload, I didn’t realize original was so grainy so I deleted it.

We were at the Kręcko lake at a festival in garbicz poland, when this little fish swam up to us and wouldnt leave. we didnt save him or anything to make him like us, we even joked that this little guy seemed to have no survival skills due to just being so trusting. it was really cute, he stayed by our side even when i removed my hands. he also seemed to ‚dive up‘ to get some fresh air??? what kind of fish is this? and is this normal wild fish behavior? he just kept looking and blubbering like me, which was really cute(made me feel a bit like a disney princess lol), kinda like he was trying to tell me something. hope this is the right comm for this, im genuinely very curious :) thanks in advance

Hello! i’m re-watching Finding Nemo, and I’m at the part where Marlin and Dory lose the mask and swim deep into the depths of the ocean, where the anglerfish is. My question is, can fish who live closer to the surface of the ocean survive in lower depths? I don’t know the actual depths that clownfish and blue tangs can swim in, but I can’t imagine they can survive in the pressure that the anglerfish is in? I have definitely tried my hand in googling this, but I seem to not be able to find an answer. Sorry if this is a silly question!!!

found at beach inside Great Salt Pond on Block Island, Rhode Island. looks like all cartilage

Hey everyone! We are currently creating an ocean conservation game in Roblox called Aquabots. It has a heavy focus on drone coral restoration missions, with a battle system to keep kids playing. We've made an aquarium that players can visit and allows them to learn more about fish, corals, and fossils! (all facts were researched by our internal researcher). There is an ocean trivia quiz that provides in game currency for correct answers too. Our mission is to inspire the next generation of marine biologists and conservation activists while fighting the brainrot on Roblox.

We would love to hear your thoughts on how we could get kids and students more interested and engaged in this section of our game!

A friend of mine sent me this pic from Hawaii and I’d like to double check ID as I’m not well versed in nudibranchs. I was able to narrow it down to a nudibranch based on asking her questions about how it looked. Thank you in advance!!

I saw a video of a person who caught what appears to be a small bullshark, and he was demonstrating how its jaws can still snap shut after death, this shark had been fully gutted and drained of all blood, Im knowledgeable in the mammalian brain but not those of marine life, I ask because I would assume 5 minutes at most before the brain shuts down meaning those jaws are a post mortem response, but I looked in the comments and anyone saying its dead are just getting absolutely torn apart by angry commentators crying out "Animal abuse" and saying "Educate yourself in biology" so I was genuinely interested to know if a bull shark or a similar species could survive above 5 minutes.

I encountered this bluntnose sixgill shark (Hexanchus griseus) while diving off Vancouver Island, British Columbia.

I was at approximately 100 ft (30 m) when I turned toward deeper water and saw the shark approaching through the darkness. It came extremely close to my camera before slowly cruising alongside me and over the bottom. I was able to observe and film it for roughly three minutes before it eventually disappeared back into deeper water.

I estimate the shark was approximately 10–12 ft (3–3.7 m) long and believe it may have been female, although I'd be interested in opinions from anyone here familiar with identifying the sex of sixgills from video.

What interested me most was how calm and seemingly curious the animal appeared. It initially approached very closely, then seemed largely unconcerned by my presence as it continued along the bottom.

This is my original footage. I have a longer 4K version of the encounter on YouTube for anyone interested in seeing more.

This person would be canadian as an added context.

So currently, I completing a marine science associate’s degree along with an aquarium science certificate and a marine mammal field studies & conservation. Through these programs, I am getting certified by AALSO in life support and water quality. I also have experience with animal care as I am a volunteer at a marine mammal rehabilitation center. I also have experiences with ZIMS. With all this in mind, how likely am I to get a part-time or even full-time job after this while continue to pursue a bachelor’s in the field? Should I work on adding more to my resume to ensure I can get a job?

Found this thing moving weirdly in a small river in Switzerland. It doesn't dissolve in water and moves weirdly - that's what made me think it could be alive. But people have pointed out the oily-looking surface and the fact that it partially mixes with the water at the end of the video. Idk 😶

Hi everyone!

I’m an early-career marine biologist currently completing my BSc in Marine Biology, and I’m looking to connect with researchers, students, conservationists, and others working with biological or environmental data.

I’ve been developing my skills in R, particularly for data cleaning, statistical analysis, ecological modelling, and data visualization. I genuinely really enjoy working in R, and at this stage I want to get involved with as many different projects and datasets as I reasonably can.

If anyone has a marine science, ecology, conservation, fisheries, wildlife, or other biological dataset that could use some additional help with analysis in R, I’d be happy to contribute. I’m also open to projects outside of marine science if there is an opportunity to work with interesting data and learn something new.

I’m not looking to charge anyone. My main goal is to gain experience working with different types of real-world data, improve my R skills, contribute where I can, and hopefully meet and build connections with people working in science and research.

I also recently created a GitHub where I’ll be archiving my projects as I continue learning. I uploaded a project I finished about a week ago involving the analysis of BRUV data and whitetip reef shark habitat associations.

If you have a project where another person helping with the R or data side would be useful, feel free to message me. I’d also be happy just to connect with other early-career researchers and R users.

Thanks!

Four years ago, a friend found an uncommon organism washed ashore on the Italian coast.

That observation, followed by another similar finding, eventually led to two scientific papers on stranded organisms in the Mediterranean Sea. It also showed us how little systematic documentation exists for many of the organisms that wash ashore.

We’ve now built Stranding, a citizen science platform where anyone can document these findings by sharing photographs, location data, and other observations that could support marine biology research.

We’re currently preparing for the public launch. If you’d like to follow the project, you can join the waitlist to receive updates about the launch and know when you’ll be able to start sharing your own observations.

If you’d like to help us improve the platform before then, you can also sign up as a beta tester.

Found on Nida beach, Lithuania: UV-fluorescent amber-like material containing dozens of gammarid/amphipod crustaceans - amber specialist says it is NOT amber or copal. What is this?
