The Atlantic Pygmy Octopus (Octopus joubini), also known as the Small-egg Carribbean Pygmy Octopus, is a small octopus species in the order Octopoda. Fully grown, this cephalopod has an armspan of only about two to four inches. It often seeks shelter from predators in empty clamshells, pulling the shells closed with its arms.
The Atlantic Pygmy Octopus has the two defensive mechanisms typical of all octopuses: ink sacs, and camouflage.
Like all octopuses, this pygmy octopus is carnivorous. It is able to bore into the hard shells of small clams or other creatures and, after secreting its poisonous saliva to paralyze its victim, eats its prey.
