How do mud snail larvae use the movement of water to survive?
A new study sheds new light on the sensory organs the snail larvae use to feel -- and perhaps even hear -- whether the water is turbulent or wavy and improve their odds of being carried to a good habitat, where they can settle down as adults. The study focuses on two species of snail, both of which live along North America's East Coast: eastern mudsnails (Tritia obsoleta), which live in inlets, and threeline mudsnails (Tritia trivittata), which live in the deeper waters of the continental shelf. The inlet-dwelling snails more often experience water that is turbulent but not very wavy; the continental shelf-dwelling snails live in a less turbulent, wavier environment.
