Favorite Snail

This little guy is my favorite snail, but I have no ID for him. I don't even know if he's good or not.

If anyone can help that'd be great.

 

Again.

 

This is this little guys snout sticking out of the sand. He's a submarine and look at his periscope. ;D

 

I BELIEVE THIS IS A NASSARIUS SNAIL, IT LOOKS JUST LIKE THE NASSARIUS SNAILS I GOT.

 

Yup, Nassaurius Snails they are!

 

THAT PERISCOPE THING IS COOL I GOT TO WATCH MINE MORE CLOSELY TO SEE IF THEY DO THE SAME

 

You all positive that they're Nassaurius? It sure looks like a glowing marginella (Marginella pruniosum). Ok, I was just being nice, it is a Marginella. I don't know much about them other then that.

 

What charcteristic makes you say that? Upon closer look the only thing I can see is that the foot doesn't trail the shell as is the case with Nassaurius. TIA.

 

Look at the pic on this page:

or this page:

notice the ruffles and coloration of the shell and the end of the shell? Now look at Davids, they're almost completely smooth with a very blunt end. On page 206 - 207 of Paul Humann's "Reef Creature Identification - Florida, Caribbean, Bahamas" book you'll find an exact match to Davids snail.

I need more Florida marine ID books, mine don't even have Nassaurius snails in them.

 

Whats TIA?
