Siphon - small tube on the ventral side of a squid/octopus that can be directed in any direction for jet propulsion locomotion. 2. Eye - sensory equipment on the head of the squid which rivals the complexity of mammalian eyes. 3. Mantle - soft skin covered organ of the squid that covers the body in place of the normal molluskan shell. 4. Tentacle - soft unsegmented appendage of a squid used for grasping prey or reproduction. 5. Sucker - small suction device on the surface of a tentacle used for holding prey or mates. 6. Pen - small and stiff support structure within the mantle used for mantle support. 7. Nidamental gland - secretes the gelatinous matrix that surrounds the squid eggs. 8. Ovary - produces eggs. 9. Buccal area - the mouth area of the squid, including the oral cavity and radula. 10. Radula - the scraping organ of feeding in mollusks, structured as a bird's beak in squid and octopi. 11. Esophagus - tube that passes food from the mouth to the stomach. 12. Stomach - digests food polymers into smaller polymers and monomers. 13. Caecum - receives food from the stomach and absorbs it to the bloodstream. 14. Intestine - receives food from the caecum and continues to absorb nutrients to the blood. 15. Rectum - receives food from the intestine to pass it to the anus and out of the body. 16. Liver - produces digestive fluids for the digestion of food. 17. Systemic heart - receives blood from the gill hearts and pumps it to the body of the squid. 18. Gill (brachial) heart - pumps blood to the gills of the squid. 19. Nephridium - the excretory organ of the squid, filtering the blood of waste products. 20. Gill - respiratory organ of the squid, exchanging oxygen and carbon dioxide between the blood and sea water. 21.
