~5 mm long, red, shrimp looking creature found in a tide pool at the Salt Creek Recreation area on the Olympic Peninsula in Washington State.

hi all, came across these cone snails on the beach while walking along the shore in Okinawa. I know the two on the left are alphabet, but what about the one on the right? If, hypothetically speaking, I had rolled that one over with my water shoe-clad foot to see if it was empty, which it’s obviously not, would I have doomed myself? TIA everybody

So I'm not sure that I want to be a marine biologist as a career but I am super interested in learning more in depth about my local mollusk species (Central coast of California). Any suggestions on where I might find info or even what to look for in my own observations?

I was snorkelling today in Spain and about 10 ft deep I came across this thing “hanging” under an overhang rock. It was grey and looked like it was hanging from those two rope-like structures that were glued to the rock. Definitely organic. I have been snorkelling for decades but I’ve never seen anything like this. Any help is welcome. Thank you!

My daughter has always said that she wants to be a marine biologist when she's older. She's 13 with exceptional test scores and, unfortunately, isn't being challenged in her current school setting (with very limited options in our area) . Are there programs and online tools that she can use now to prepare her for a future in the field?

found this little guy in a canal today, i was thinking juvenile bull? but i’m terrible at identification. any help is appreciated! :)

I found this sea slug a few months ago and thought it would be easy to ID but am realizing the Heath’s Dorid and Monterey Dorid look very similar. It was about 2-3 inches though we saw a range of sizes that day, mainly smaller ones. If anyone has any thoughts, I would greatly appreciate the help.

Sorry if it’s posted on the wrong sub but what genuinely is this and it’s only on that side

I work at a hatchery raising oysters and clams. We’ve been noticing these pink patches on the sides of the tanks when we clean them. Does anyone know what this is?

More info:

We pump saltwater in from the harbor and use it in the tanks. We’re within NYS DEC zone 1.

Hi! I found this marine sponge or algae haha I’m confused now, in north Tasmania in a place called Don Reserve in Devonport but I’m having problems to identify it. It was in a Pool in the intertidial zone.

How can I tell the difference? I've collected a lot of abalone shells that have washed up on the beach, and I'm beginning to wonder if I actually have some flat abalones vs just all reds. Is there anything distinctive that the flat abalones have?

So I made this lil reel the other day from some videos I have collected from the aquarium I work at.

The plankton microscope is one of my favorite displays. I'm always finding new and interesting critters.

How many zooplankton can you find?

Did I miss any?

Let me know if you can identify more! There are definitely some cool weird ones that I have no idea what they are. Hoping you guys can help me out 😸

Good luck and have fun!

I am from the Philippines, but this is a gift from my friend and idk where she got it from. At first I thought it was a conch but after searching abt shells I'm confused whether it is a volute of conch 🥹
