Yes, lobsters have teeth in their stomach. These teeth are part of a system called the gastric mill. Did you know lobsters have two stomachs? One is located behind their eyes. This stomach has teeth-like features to crush food. Once the food is crushed, it goes to the other stomach located in the abdomen.
Lobsters “smell” their food by using the four small antennules on the front of their heads and tiny sensing hairs that cover their bodies.
A lobster will use its crusher claw to break open shellfish and its ripper claw to tear food apart. The two sets of walking legs (or pereiopods) immediately behind the claws are also used for catching and eating food and have many “taste” sensors. They are used to move food into the mouthparts or maxillipeds. The teeth of the lobster are in its stomach. The stomach is located a very short distance from the mouth, and the food is actually chewed in the stomach between three grinding surfaces, called the gastric mill, that look like molar surfaces.
