Ligumia subrostrata (the Pondmussel) is an inhabitant of small streams and shallow portions of lakes and ponds. It utilizes centrarchids (bass, bluegill) as hosts for it’s parasitic young. Fish are attracted by a mantle lure that resembles small invertebrate prey. When a fish attempts to inhale the “lure” the marsupium (white portion in video) bursts and glochidia larvae clamp onto the unsuspecting fish. In Alabama, we have observed L. subrostrata displaying from January through May.
