Which of the following animals have teeth in their stomach?

  • A.Frogs
  • B.Crabs
  • C.Snakes
  • D.Cockroach

Answer: B

Crabs have teeth in their stomach. The gastric mill is a set of chitinous plates in the foregut that grinds food after it is swallowed.

Crustaceans have no jaws capable of chewing, so the grinding is done internally, and the mill is worked by muscles attached to the stomach wall.
