What the heck is a Lamellarid?

[JahISeek]

My husband brought this home from the LFS. They say it eats algae... but I have since learned that they dont always tell the truth

Anyhow, after hours of searching it is either a "Coriocella Nigra" or a "Chelyonotus Semperi"...

Any ideas or info on it would be GREATLY appreciated.

I'm nervous about adding it to our tank.

Thanks for any and all info.:eek1:

Most if not all eat ascidians aka tunicates aka sea squirts. I doubt you will ever see it eat. It will probably not live long in your tank. I haven no idea if it is toxic or not.

Family: Lamellariidae
"Lamellariids, or as they now should be called, velutinids,(formerly Family Lamellariidae), are caenogastropod snails, closely related to the Triviidae. In most velutinids the shell is open and flattened, much like a small abalone shell (Haliotidae), and at least partially enveloped by the fleshy mantle. This gives them a fleshy shell-less appearance which often causes them to be mistaken for sea slugs. In most cases when they are crawling a pair of head tentacles will emerge from beneath the body, instantly showing that these are not opisthobranch sea slugs. Another character is the anterior siphon above the head which opens into the mantle cavity.
Velutinids all seem to feed on colonial ascidians and many, like the species illustrated, are well camouflaged by their similar colour. Some species however, including some of the large tropical species of Coriocella, are very brightly coloured. This may be a defensive response, as described for many nudibranchs..." SeaSlug Forum
