Cyphoma sp.

Triangular cyphoma

Maximum length:?

I photographed this snail in Bonaire,

it was a maximum of 1 cm long and belongs to the ice snail category,

but which one is it exactly? In any case,

I haven't found anything that even remotely resembles it.

Today, on 28.10.2017 after inquiries in the WWW,

I found out that this species has not yet been named.

31.10.2017 today I was told that this species is not yet described,

so the name Cyphoma sp.1 is correct .
