Name the beetle that eats its own discarded skin to survive?

Answer 1

Both the diving beetle and the dytisidea both are vicious predators. The dytisidea is nicknamed the water tiger. They both eat anything they can find in the water. They eat small aquatic animals like fish, water insects, leeches, snails, and tadpoles. It even eats its own kind! Nobody eats it. The diving beetle and the dytisidea are on the top of the food chain.
