Sea Slug

[BOD]

I think i have one are they good/bad? It was probably and inch long white with black patches looks pretty harmless he was going across the glass muching alage i think ??? I should have took a pic but just didnt think at the time and now he has gone away!

 

[Mr Miagi]

We couldnt tell you whether its god or bad without a picture/ID.

 

[SkiFletch]

Agreed, Without an ID we cant tell for sure, but most sea slugs are ok so long as they are both eating, and not eating things you want to keep. Keep an eye on it though, some slugs emit really nasty stuff when they die

lol, it looked pretty harmless, as soon as i see it again ill take a pic, but since then i have not seen it!

Did you actually see it munching at the film algea on the glass, like with the raspy toung (the radula)? If so I'd say that you had a stomatella snail, which have an insignificant abalone shaped shell on there back. I say this because sea slugs tend to have more speciallised feeding parts rather than the generalised radula for scraping, they tend to suck things dry.

basically it looked like it had a snail mouth, and was munching across the glass.

 

[Mr Miagi]

Well did it look like a stomatellid? Stomatellid on google image search. Or did it look more like a nudy? A Nudibranch Google image search.

 

[BOD]

It definatly looks more like a Stomatella rather than a nudibranch

Limpits look a lot like slugs

 

[Mr Miagi]

Limpits look a lot like slugs

But they have a dome shapped shell. A most distinguishing characteristic.
