Unfortunately, I don't know what species it is, but based off of the shell it's highly like that it's a Muricid (Murex) snail of some variety - it's probably from the Muricinae subfamily, but I'm not entirely sure. So, it's not technically a whelk which would be from family Buccinidae (though the term is frequently used as a catch-all for all predatory snails), but it's still from a predatory family (Muricidae). I have heard but cannot confirm at this point that - like with the Buccinidae - not all Muricid snails are predators, just most of them are.Still keeping track of this guy. He’s grown to about 1/2 inch now and still seemingly not bothering anyone. He’s a fairly lazy guy as far as I can tell… sitting in the same places for days at a time or lazily letting the turbos carry him for a few days. Still wish I really knew what he is!
Regardless, if it hasn't caused you any problems, it's a very cool hitchhiker - I love the layers visible on the shell.
