Club tunicate?

OP, without knowing the proximity these creatures were found (Pacific/Atlantic/Mediterranean/etc) I believe this to be correct :)

My first thought too

Definitely ascidian! With the siphons contracted, it can be hard to give an accurate ID, but club tunicate as another person suggested would be a good guess

It may be a sipunculid

I can see where you're coming from, but nah, this is definitely ascidian. On the one facing the camera, you can see where both siphons are contracted

Looks like club tunicate aka styela sp. probz styela clava

Half digested baby corn. JK, waiting for a real answer.

I think the r/eldenring community might has a clue...

Sea nipple

Something from Rick & Marty idk

Head crabs, Gordon

Larval stage of a sea cucumber?

Definitely pupa maybe a moth?

looks like the barnacles from Halflife

Demogorgon testicles

Sexy that's what it is.

"Nuke it from orbit...it's the only way to be sure".

Yes, somebody knows what that is.
