Knowra Amphioctopus marginatus Amphioctopus marginatus Amphioctopus marginatus is a small octopus found in the tropical Indo-Pacific. It gathers discarded coconut shells and other objects, carries them, and assembles them as shelters.
Tool use in animals : Tool use in animals is the employment of external objects to achieve goals such as obtaining food or protection. This octopus carries shells that it later positions as defensive shelters.
Coconut-carrying octopus : The coconut-carrying octopus is a common name for Amphioctopus marginatus, noted for transporting coconut shells as shelter. This name highlights the species' best-known observed behavior.
Octopus : An octopus is a soft-bodied marine mollusk with eight arms, a beak, and a mantle enclosing its organs. Amphioctopus marginatus belongs to this group of highly flexible, predatory cephalopods.
Veined octopus : The veined octopus, Amphioctopus marginatus, is a small Indo-Pacific octopus known for carrying coconut shells and other objects. This alternate common name can obscure that it is the same species, not a behavioral rival.
Animal shelter : An animal shelter is a structure or refuge that protects an animal from predators or environmental conditions. Coconut shells provide this octopus with a portable refuge on exposed seafloors.
Julian Finn : Julian Finn is a marine biologist who coauthored the 2009 report documenting tool use in Amphioctopus marginatus. Finn and colleagues described shell collection, transport, and assembly in the species.
Amphioctopus : Amphioctopus is a genus of benthic octopuses in the family Octopodidae. The species is one member of this genus of bottom-dwelling octopuses.
Octopus cyanea : Octopus cyanea is a large Indo-Pacific octopus known for active daytime foraging and dynamic camouflage. It illustrates a related octopus whose conspicuous hunting contrasts with shell transport as a signature behavior.
Coconut : The coconut is the large, fibrous fruit of the tropical palm Cocos nucifera. Discarded coconut halves can become durable, hollow shelters that the octopus transports.
Octopus tool use : Octopus tool use is the use or transport of external objects by octopuses to support later actions. The shell-carrying observations are a documented case of this behavior.
