California two-spot octopuses (Octopus bimaculoides) sometimes called “Bimacs” for short, gets their common name from the iridescent blue circles, known as ocelli, on both their sides. Their skin is a mottled brown color, but can change the color and texture to hunt, hide, and mate.
Bimacs have three hearts, two gills, blue blood, and a donut-shaped brain. Like other members of the cephalopod class, it can instantaneously change color, regrow arms, and uses jet propulsion to move through the water. Its eight arms exhibit incredible flexibility and dexterity. The arms are lined with hundreds of suckers an octopus can use to “taste” its surroundings.
Like most octopuses, O. bimaculoides die after the first time they reproduce. After mating, octopus mothers guard their eggs for two to four months, during which they stop eating and quickly deteriorate.
