- Physical Characteristics:
- Tentacles with suction cups or hooks for grasping prey.
- Arm “mini-brains” with distributed neurons.

- Squids: E.g., Architeuthis dux (giant squid).
- Nautilus: Chambered mollusc with external shell.
- Special features:
-

- Associative learning and memory comparable to vertebrates.
- Ability to delay gratification (e.g., choosing a preferred snack over immediate lesser options).
- Problem-Solving: Uses tools and strategies to escape enclosures or hunt.
- Camouflage Skills: Advanced use of chromatophores for disguise and communication.
