Snack time? Look closely and you will see this octopus in Gray's Reef National Marine Sanctuary is eating some shellfish!
But how do octopuses eat, anyway? An octopus's mouth is on its underside and contains a hard beak. The beak is made of chitin, a material similar to what's in your fingernails, and helps the octopus chow down on tough food! (Photo: P.
