Anyone recognize this guy?

The stalk is about an inch long and goes down into the sand. It is soft and retreats down when poked with a stick.

Looks kinda like a sand anemone. Does the top ever change shape or open up?

 

[1ocean]

sort of looks like a relative to a bobbit worm mouth and shape......if so very bad thing...

I think I've seen something like this on R2R a few days ago, I think it was a coral eating nudibranch but I'm not sure, @ISpeakForTheSeas?

Also maybe peanut worm?

 

[1ocean]

are you missing fish? Kinda weird looking, the anemone tentacles coming from mouth area. What ever it is looks like it is built to eat what ever comes it way...Could be bad if you touch it, sting you etc..

 

[ISpeakForTheSeas]

Can you get a top-down, straight-on pic of the mouth?

It is right on the edge of thick glass so I’m having trouble getting it to focus if the angle is too steep.

This thing is adorable! And I'm fairly convinced it's an anemone after this picture.

yep very strange...looks like a eating machine....

Seeing could help with saying for certain, but as is I'm relatively confident it's an Edwardsiid (taxonomic family Edwardsiidae) anemone, sometimes called "Worm Anemones."

Assuming it's in a tropical tank, that would narrow the possible genera down to five different ones (Edwardsia, Edwardsianthus, Edwardsiella, Nematostella, and Scolanthus [Edit: forgot Paraedwardsia, though it's an unlikely one]); out of those, an Edwardsia sp. seems the most likely to me - unfortunately, the genus contains dozens of species and I haven't looked through them all, so I'm not sure which one at this point, but here are two (linked below) that look relatively close:

Edwardsia sp.02 Burrowing sea anemone, Sand anemone

Edwardsia sp.02is commonly referred to as Burrowing sea anemone, Sand anemone. Difficulty in the aquarium: Very easy. A aquarium size of at least 20 Liter is recommended. Toxicity: Toxic hazard unknown.

Edwardsia sp.03 Burrowing Sea Anemone

Edwardsia sp.03is commonly referred to as Burrowing Sea Anemone. Difficulty in the aquarium: There are no reports available yet that this animal has already been kept in captivity successfully. Toxicity: Toxic hazard unknown.

... And now I need one.

Haha, they are pretty cool - lots of neat coldwater species in the family too.

It looks quite a lot like starlet sea anemone (Nematostella vectensis), thank you for your help!
