Why do otters carry rocks
Otters carry rocks primarily as tools to help them eat. Sea otters, in particular, often have a favorite rock they use to crack open hard-shelled prey like clams, mussels, and abalone.
They use their chest as a table, placing the rock on their stomach and smashing the shellfish against it to break the shell. Because these rocks are so useful for foraging, otters will often store them in a loose flap of skin under their armpit, which acts like a built-in pocket, to keep the tool handy for their next meal.
Additionally, some researchers believe that young otters may carry and play with rocks as a way to practice the dexterity and manipulation skills they will need for foraging as adults.
