The striped pyjama squid is one of the few known poisonous cephalopods (squid, octopus, cuttlefish, and nautilus) that roam the seafloor of the Indo-Pacific Oceans, along with the flamboyant cuttlefish and the southern blue-ringed octopus. Scientists believe that the striped pyjama squid’s distinctive black stripes give away its venomous nature to potential predators, but small glands under the body are responsible for releasing the toxic slime that is dangerous to passersby.
