Sea otters have flaps of loose skin under each forearm that they use like a pocket. That’s it. That’s the post. Just kidding. Let’s dive in. ⁣ ⁣ What are these pockets full of? Well, it’s not sunshine. When swimming, the pockets are used to carry as much food as possible back to the surface. (Think buffet. You’ve already got a plate piled high of seafood and then you see hot rolls…oh, is that a pie? Alright! Let’s do this.)⁣ ⁣ Otters also use their pockets to stash rocks. Rocks are used to crack open clams, crabs and other shellfish on their tummies. (Tummies is the preferred lingo.) They may also use rocks to hammer abalone shells, as quickly as 45 times in just 15 seconds (hammer time!), until the abalone loosen their tight grip on the seafloor. ⁣ ⁣ Have rock, will travel. Many otters have a favorite rock that they store in their pocket, carrying it wherever they go. Some may even name their rocks. All hail “Sir Cracks A Lot,” bringer of otter destruction! Something like that. Resear...
