Natural Fish Lure | Lampsilis Mussel and Bass
Description: The Lapsillis mussel must spend part of its life cycle within the smallmouth bass. It has evolved a lure that resembles a small fish so that it can squirt its young into the mouth of the bass. The mussel is even able to twitch the lure as the bass approaches.
