Common name: Octopus

Octopoda is an order within the class Cephalopoda, known for the highly intelligent and behaviorally complex octopuses. Members of this order have eight arms, a soft body, and lack a shell. Octopuses are known for their ability to change color and texture, escape from enclosures, and use tools. In the aquarium, they require a species-specific setup with secure lids to prevent escape, and enrichment to stimulate their intelligence. They are generally not reef-safe as they may prey on small fish and invertebrates.
