Do the Funky Conch Hop

A conch is a kind of snail, right? And snails don’t jump; they ooze, right? Well, not always, it turns out. Here, from Science News, is a story about the motion of Gibberulus gibberulus gibbosus, aka hunchbacked conch.

To quote: “The sea snails save their jumping for conch emergencies, such as when they detect dissolved body odor from the deadly cone snail Conus marmoreus. Cone snails glide rather than jump. But if a cone snail gets close enough, it harpoons the conch with a long, venom-delivering proboscis that is as agile as an elephant’s trunk. Then it reels in the paralyzed conch like a fish on the line. Such threats favor epic jumping in spite of the conch circulatory system…” [more]
