Two Spot Octopus

(Octopus bimaculatus)
Population status in the wild: Least Concern

The Two-Spotted Octopus is a small species of octopus native to the coastal waters of the eastern Pacific Ocean, particularly off the coasts of California and Baja California. This species is named for the two distinctive spots located near its eyes—one on each side of its mantle—though its coloration can vary. The body is soft and bulbous, with a light to reddish-brown color, and the octopus’s arms are typically short, covered with suckers that allow it to grip and manipulate objects with precision. The Two-Spotted Octopus generally grows to around 8 to 12 inches in length, with arm spans that can reach up to 24 inches.

The Two-Spotted Octopus is a carnivorous species and feeds primarily on crustaceans, small fish, mollusks, and other invertebrates. Using its powerful arms and suckers, the octopus hunts by ambushing its prey or by using its ability to change color and blend into its environment, making it an effective predator. In aquariums, they are fed a variety of live crustaceans, shrimp, and small fish.

This species is known for its high intelligence and problem-solving abilities, which are characteristic of many octopuses. The Two-Spotted Octopus has excellent camouflage capabilities, able to change the color and texture of its skin in response to its environment, making it nearly invisible to both prey and predators. It also has a highly developed nervous system and is capable of learning and remembering tasks, such as opening jars to access food.

The Two-Spotted Octopus is typically found in rocky reefs, kelp forests, and sandy bottoms in shallow waters, usually at depths of 15 to 100 feet. It is solitary by nature and spends much of its time hiding in crevices or burrowing into the substrate, where it can seek shelter from predators like sharks, larger fish, and sea otters. The Two-Spotted Octopus has a relatively short lifespan, typically living for 1 to 2 years, although some individuals may survive up to 3 years in the wild.

Fun Facts:
The Two-Spotted Octopus is known for its ability to change color and texture, blending seamlessly with its surroundings to avoid predators or ambush prey.

This species is incredibly intelligent and can solve complex problems, including opening containers and escaping enclosures in research settings.

Like many octopuses, the Two-Spotted Octopus is capable of regenerating lost arms, which is an important survival trait.
