Greater Blue-Ringed Octopus
Hapalochlaena lunulata

This small octopus inhabits shallow tropical reefs, tide pools, and sandy coastal bottoms. It stalks crabs, shrimp, and small fish, using camouflage before seizing prey with its arms and beak. When threatened, bright blue rings flash across its body as a warning of its exceptionally potent venom.
