Sotong Berbintik Biru

Sotong Berbintik Biru (genus Hapalochlaena) merupakan tiga atau empat spesies sotong yang hidup dalam kolam pasang-surut dan batu karang di Lautan Pasifik]] dan Laitan Hindi, dari Jepun hingga ke Australia (terutamanya di selatan New South Wales dan Australia Selatan). They are recognized as some of the world's most venomous marine animals. Despite their small size and relatively docile nature, they can prove a danger to humans. They can be recognized by their characteristic blue and black rings and yellowish skin. When the octopus is agitated, the brown patches darken dramatically, and iridescent blue rings or clumps of rings appear and pulsate within the maculae. Typically 50-60 blue rings cover the dorsal and lateral surfaces of the mantle. They hunt small crabs, hermit crabs, and shrimp, and may bite attackers, including humans, if provoked.
