Life habits of Pipi shrimp:

Mantis shrimps often live in burrows, often digging burrows on the sandy bottom or silt bottom of shallow seas. The burrows are mostly "U" shaped. Stomatopods are carnivorous and mostly prey on small invertebrates. Such animals can make sounds by rubbing the ventral surface of the telson with their tail limbs or striking with their sweeping limbs.

Mantis shrimps are ferocious and have very sharp eyesight. Because it is good at swimming, most of its prey are benthic creatures that are not good at swimming, including various shellfish, crabs, sea urchins, etc. They can easily break the outer hard shell of their prey and feast on the meat inside.

Mantis shrimp are very good at laying ambush. Powerful attacks can kill enemies. Lobsters covered in calcified armor and crabs quietly passing by on tiptoes are also often attacked by mantis shrimps. A violent blow from the mantis shrimp's two hammer segments can destroy the crab's nervous system and kill it instantly.
