Fans of marine trivia may already know that a starfish is a messy eater. Instead of putting prey in their stomachs, many starfish species put their stomachs into their prey, throwing up this organ inside-out and letting its acidic juices break down the food into nutrient soup. Then the starfish slurps up its meal, sucks its stomach back in, and shuffles on its merry way.
Because starfish like to dine on bivalves like mussels, which hide away in an opaque shell, it can be pretty hard to watch a starfish in the act of eating. Unless you have this incredible time-lapse video from Shape of Life on Vimeo, which shows the process from the mussel’s meal’s point of view.
