The day octopus, Octopus cyanea, in a tank in the laboratory
Octopuses are mollusks, a large evolutionary group to which slugs and snails also belong. Their complex brains, and those of other closely-related cephalopods, like squid and cuttlefish, have evolved separately from vertebrates, and so octopuses are often referred to as alien-like. Here, a day octopus (Octopus cyanea) poses with a Shisa, a creature from Okinawan folklore.
