Can you bite into a walnut? It would hurt your teeth! Crack! Use a nut cracker. Then nibble the tasty nut. Sea otters use rocks and shells to break open clams.

That protects their teeth!

Pray: Thank God for giving creatures smart ways for getting to yummy food.

People use nut crackers and knives to cut into food. Scientists watched 196 southern sea otters in California. The critters use shells, rocks, and bottles to open mussels, snails, and clams. Sea otters float on their backs. They put rocks on their bellies. The rock works like a table. Bang! They hit the food with another hard object. Crack! It opens. Females use tools the most. They are smaller. They cannot bite down with as much force as males. Females also show less tooth damage!
