Navigates rushing streams underwater by its powerful, muscular foot, using it as both a suction cup and an organ of motil-ity. If disturbed, individuals release a bioluminescent substance based on the chemical interactions of luciferin and luciferase, as in a majority of bioluminescent animals.
Most likely employs its bioluminescence as a defense. The luminous substance, when released by the animal, forms into tiny, individual globules or droplets that could act as lures, the bright, speeding blobs stimulating a predatory fish into chasing the droplets and not the limpet. Or, the bioluminescence may serve to induce a "startle response" in a predator, halting and confusing it while the limpet crawls to safety.
