Exciting change is on the way! Please join us at nsf.gov for the latest news on NSF-funded research. While the NSF Science360 page and daily newsletter have now been retired, there’s much happening at nsf.gov. You’ll find current research news on the homepage and much more to explore throughout the site. Best of all, we’ve begun to build a brand-new website that will bring together news, social media, multimedia and more in a way that offers visitors a rich, rewarding, user-friendly experience.

Want to continue to receive email updates on the latest NSF research news and multimedia content? On September 23rd we’ll begin sending those updates via GovDelivery. If you’d prefer not to receive them, please unsubscribe now from Science360 News and your email address will not be moved into the new system.

Thanks so much for being part of the NSF Science360 News Service community. We hope you’ll stay with us during this transition so that we can continue to share the many ways NSF-funded research is advancing knowledge that transforms our future.

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.
