Behavior
Octopuses are solitary, intelligent hunters that use problem-solving and camouflage. They can open jars, solve mazes, and recognize individual humans. They are masters of escape.
Reproduction
Females guard eggs for weeks without eating and die shortly after they hatch. Males also die soon after mating. This short lifespan limits what they can learn.
