Octopuses have the most advanced nervous system of all invertebrate animals and are active hunters.

• Powers: Ink shots, camo, limb regrowth
• Hearts: Have three hearts
• Architects: They build underwater cities
• Arm Brains: Most neurons in their arms

Octopuses are Cephlopods known for their 8 arms, which contain 2/3rds of their neurons. This means the arms can taste, touch, and even act on their own accord, without input from the brain.
