Mussel Larva Dispersal
Freshwater mussel larvae, called glochidia, are parasitic on the gills of fishes. The female uses a worm-like or prey-mimic lobe of the mantle to lure a suitable host close enough to discharge the glochidia into the mouth, where they can attach to the gills, as in this Youtube video.
