Looks like a slug

Any idea? Came on a frag.

Nudibranch?

 

[Rugops]

A nudibranch indeed. As for the species - I don't know.

Keep it or toss it?

 

[Rugops]

Maybe you can keep it until you find out what it is (in a container of course). You could throw it out if you don't care.

Can you get a straight-on, top-down pic of it so you can see it’s entire topside in the pic?

The pic is pretty dark - can you get one that’s better lit?

Here's a bright one.

 

[StatelineReefer]

Tempted to say Dendrodoris Nigra, due to the coloration and the gill formation.

Sponge eater... not a generalist either.

Just to be sure, might this be some kind of fleshy limpet species?

Visible rhinopores and gill structure on the back tell me Dorid.

Visible rhinopores and gill structure on the back tell me Dorid.

I see what may be a gill structure, but I'm struggling to see rhinophores (I see what looks like they may be cephalic tentacles like you'd find on snails, and I suppose those could be rhinophores at a bad angle); the thing that's really making me question this being a nudibranch though is the raised rim of the fleshy skirt around a central white/cream colored structure in a very neat oval shape.

Regardless, if it is a nudibranch, I very strongly doubt it's D. nigra.

Is it a snail?

Fleshy limpet, elephant snail?

Scutus antipodes?

Whered you get this frag?????

 

[Double monti 61]

I agree with scutus.I had on once.

 

[ISpeakForTheSeas]

Scutus antipodes?

Thank you for reminding me about these guys.

The color looks wrong for a typical Scutus antipodes, but I have seen at least one with this sort of coloration that is labeled S. antipodes* (I'd guess it's a different species in the genus). So, I'm thinking something along those lines - either a Scutus sp. or a different limpet with similar habits (there are quite a few members of the Fissurellidae family that do similar things, but only a couple I've seen have similarly shaped shells).

Is it a snail?

To make a long taxonomic explanation short, I would guess so, yes - and most likely an algae eater.

*The source of the image of the specimen with similar coloration that I've seen:

Scutus (Scutus) antipodes (Montfort, 1810), Elephant Snail

Elephant Snails emerge at night to graze on seaweeds. They were commonly eaten by Aboriginal people, who cut away the black flesh to eat the muscular foot. The black mantle usually partially covers the shell, but when disturbed the snail pulls the mantle back, exposing the shell.

At a frag swap in Pennsylvania.
