Characteristics
Gonodactylaceus mantis shrimps share several defining features:
- Powerful Claws: Their most notable feature is their massive, club-shaped claws, which are used to stun and kill prey. These claws are incredibly powerful, capable of delivering strikes with forces exceeding 1,500 Newtons, generating cavitation bubbles that can kill fish.

- Burrowing Behavior: Most Gonodactylaceus species are burrowers, creating elaborate shelters in coral reefs, rocky shores, and sand flats.
- Carnivorous Diet: They are primarily carnivorous, feeding on a variety of prey, including crabs, snails, and fish.
Environments
