Hello, this is a shell that I caught in Florida, in the caribbean coast on Chokoloskee town. ¿Is this Crepidula fornicata? I hope that be another specie.
Thanks.
It looks like C. fornicata.
P.s. On the following link you can find many photos and scientific names with which you can contrast it, but sadly it does look like C. fornicata.
