The blue-ringed octopus is a mollusk with venom powerful enough to kill humans. They are a apart of the kingdom Animalia, phylum Mollesca, class Cephalopodo, order Octopodo, family Octopodidae, subfamily Octopodinae, and genus Hapalochlaena. The characteristics of mollusks include a complete digestive track, shells, and fully developed organs. The blue-ringed octopus has all the characteristics, and is able to mate through a mating ritual that includes a packet of sperm being forced into a female of the species. The behavior of the blue-ringed octopus is unlike that of regular mollusks, as it can use chromatophore cells to camouflage itself and feed on other sea dwellers. Its diet include other mollusks such as crab or shrimp, and it uses its horny beak to break through the exoskeleton of these species. When in danger, the octopus will turn yellow with blue rings on it as a warning towards danger. This organism relates to our vodcast "Invertebrates 1" since it is a type of invertebrate and fits under a specific phylum. This organism shares all the characteristics of this phylum and has grown more advanced with an advanced warning system and a way of protecting itself from harm.
