Why do lobsters have big claws?
For grown-ups: the science
Lobsters have big claws to catch and eat food and to protect themselves.
Many lobster species have two differently shaped claws: a larger crusher claw with blunt teeth for breaking shells and a cutter claw with sharper teeth for tearing food. Claws also play roles in defense, competition, and handling objects. Claw size and shape vary by species, sex, age, and which side is dominant.

A lobster walks along the rocky ocean floor with two giant claws. Why are its claws so big?
A lobster uses its claws to grab food, like clams and small sea animals. The claws help it hold a slippery meal.
One claw is often bigger and stronger for crushing hard shells. The other claw has sharper edges for cutting food.
Lobsters also lift their claws to protect themselves from other animals. Big claws can pinch and help a lobster stay safe.
So, lobster claws are big because they help with food and protection. They are useful tools under the sea!
