Poison Ocellate Octopus or Mototi Octopus (Octopus mototi) -
Although it looks similar to the Carribean Two Spot octopus, this little octopus is actually poisonous. It is a type of blue ring octopus. Found in the waters of Japan to Australia and the South Pacific. In the Rapa Islands, “mototi” means poisonous.
While resting or calm, it is a camouflaged yellow brown, and its ocelli are very faint. (From top to bottom) As it becomes more threatened, it begins to sport bright white body with dark brown stripes, and flashing its blue rings to warn the enemy of its poison. Sometimes it bears these color patterns while swimming or when it is exposed.
These octopus are very rare in their native waters. It is not yet categorized on the ICUN list.
