Peppie shrimp ferocious temperament, vision is very sharp. Because they are good swimmers, most of their prey are benthic creatures that are not good swimmers, including a variety of shellfish, crabs, sea urchins and so on. They can easily destroy the outer hard shell of their prey and enjoy the meat inside.

The shrimp is also known as the "mantis shrimp" and is very good at ambushing. A powerful attack can kill an enemy. Lobsters wearing calcified armor and crabs passing quietly on their tiptoes are also common targets for the mantis shrimp. A violent blow from the mantis shrimp's two hammer segments can destroy the crab's nervous system and kill it instantly. It uses its barbed arms under its head to dart at its food, much like a praying mantis.
