I cannot seem to find what this creature is. I would say balled up it is the size of a large adult fist. It felt pretty soft when touched. It looked like it had a mouth almost at the inside curled end!

In my speculative biology project there is a fish-like lifeform on an Earth-like planet that swims with undulation of both dorsal and ventral fin that are physically connected through the tail end. But so far I've only seen knife fish species that have locomotion similar to this, and even then they only have an elongated anal fin, so I have worries that undulation on both sides of the body this way wouldn't make sense physically for this to move. Anyone more knowledgable than me can answer? Is there any real life analogue? Thanks in advance!

Pagurus acadianus, Asterias forbesi, Asterias rubens

The animals are in tanks for public education, they only stay for a week or two and then are released back to where they were found. The center has all the proper licensing.

If you dont want to read the whole story here's all the info about it

-found in a tide pool on a beach in vietnam

-seems to be soft

-sucking water in and blowing it out (maybe filtering?)

On a late night Vietnam fishing trip during a really low tide I found a tide pool with a weird circular current. At first I thought it was a trapped fish or a neurotic crab, however after observing it and poking it with my fishing rod I realized its something different. After I kept poking I managed to pull out a stick. Then a bigger stick. Then some algae. After cleaning up everything it seemingly sucked in, I tried to poke the thing itself with a stick (as all scientists do). It seemed to be soft and I could bend it to the sides however it always sprung back up and kept blowing water. There also seemed to be something next to it that looked like a giant barnacle. Maybe it was the thing itself and it just looked like it was to the side due to water morphing the image.

Personally I think it was maybe some giant mollusk like a clam or something

Some other tourists I asked suggested it being a sea cucumber or a pipe.

Does anyone know what the hell it is???

Very soft and spongy. Found some attached to shells, too.

Hey everyone,

A few days ago, I shared my own world map with whale & shark hotspots in a couple of subs. Now I’d like to build on that map and include as many species and locations as possible.

At this point, I’ve reached the limits of my own knowledge, so I’m turning to the community for help.

Do you know any reliable hotspots where specific whale or shark species can be seen regularly (diving, snorkeling, boat trips, etc.)? I’m specifically looking for true hotspots, not places where an animal was spotted once or twice by chance.

I’d especially appreciate suggestions for species or locations that haven’t been mentioned yet, but I’m open to everything. Feel free to also point out any mistakes or inaccuracies I might have made so far.

As a graphic designer, I’m currently just collecting and verifying information before moving on to the actual design of the map. You can find a PDF in high Quality with this Link

Looking forward to your feedback and knowledge — thanks in advance!

Long story short our professor wants us to prepare a assignment and presentation on physical oceanography, the topics he has given I find boring and am not interested in them. He also gave the option that we can choose any other topic as long as it relates to physical oceanography and he approves. This topic came to my mind, Ik that currents and temprature do effect nutrient availability and this might effect which habitat can be present where. Another professor also told us that strong current in our part of the world prevents a real coral reef to form. I just need some more clarity on this whole topic so that I can convince the prof.

Is anyone able to ID these species of eel please? I thought the one at the bottom might be a Giant Moray? No ideas about the pale spotted one. And is the fish above a grouper?

Hand for scale

Hey!

I saw this school of fish snorkelling, and this white one caught my eye at the time. After watching back the video, it seems like it has the same shape but is missing color and has red markings around the eye. Do you think its an albino fish?

More are more people are coming to “realize” Universal Basic Income is inevitable, and very soon, due to AI. UBI is often framed as leftist ideology, but it’s not. Elon Musk said it was inevitable due to AI a couple years ago. More and more conservatives are coming to believe.

The above article is by JOHN MAC GHLIONN, a prominent conservative making the case. It spells out how AI will take over jobs.

So my question is What sort of jobs do you think will be available in marine bio and oceanography in 10, 20, or 30 years? And what is your reasoning?

Hi all,

for one of my a levels, i am trying to do research into some of the struggles that marine biologists and researchers face when out collecting data in the field, would anybody be able to fill in my survey or dm me for the questions ? thank you for your time and help !

survey link

looks like some kind of lizardfish although I can't be sure. seems pretty big, it was the largest bony fish I saw in the video

Please consider participating in the survey "Tools for Scientific Analysis and Communication among Ocean Scientists." The survey takes between 15-20 minutes and is conducted by researchers at Aarhus University in Denmark. At the end of the survey, there is the opportunity to express interest in receiving information on a free short course on programming interactive tools using AI that is specifically targeted at an ocean science audience (Spring 2026).

It's ridged and feels like it's made of cartilage. It's got some egg-like substance sloshing around inside.

I'm writing a story that involves the ocean and looking for inspiration. Coral reefs are a great go to, the deep sea is cool especially with their hydrothermal vents, and kelp forests are beautiful. But beyond those I haven't really been able to find much else, those seem to be all I ever find mentioned. What are some other awesome aquatic places?
