Here is a little lunchtime video—literally. Many species of starfish (or, more properly, sea stars; they are not fish but rather echinoderms) have a unique method for feeding on bivalves like clams or mussels (their typical fare). A sea star will crawl on top of a misfortunate* mollusk, use tube feet to pry open the shell, and then vomit out its own stomach, inserting it into the bivalve shell, digesting it remotely. When it’s done, it simply retracts its stomach. (Imagine what buffets would be like if we could do this.) Getting this on video was always a tough proposition, but now, via Discover, for the first time there is very cool video that gives us a “meal’s-eye view” of this process.   *Or perhaps “star-crossed.”
