Veined octopuses observed off the coast of Indonesia carried coconut shell halves under their bodies, and assembled them as necessary into shelters ? something that wasn?t supposed to be possible in their corner of the animal kingdom.
?To date, invertebrates have generally been regarded as lacking the cognitive abilities to engage in such sophisticated behaviors,? wrote Museum Victoria biologists who described the octopuses in a paper published Monday in Current Biology. ?The discovery of this octopus tiptoeing across the sea ?oor with its prized coconut shells suggests that even marine invertebrates engage in behaviors that we once thought the preserve of humans.? ]
