Tentacles underneath Trochus snail

[Acros]

I have 4 trochus snails I inherited during an aquarium purchase. They are all well and active. However, they have about 6-8 small dark-colored tentacles underneath them. This is in addition to their antenna. Any idea what that is?

Part of the animal... nothing to worry about. I breed and sell Trochus.

Thanks. I was not sure if it was a pest.

Nope... just feelers they have around the perimeter... awesome animals
