Squid Anatomy Study Notes

Tentacle: Long, flexible limbs used for grasping prey; often equipped with suckers for grip.
Arms: Shorter than tentacles, these limbs are used for manipulation and locomotion; typically have suckers along their length.
Eye: Highly developed organs providing excellent vision; similar to vertebrate eyes, allowing squids to detect movement and changes in light.
Funnel: A muscular structure facilitating movement and expulsion of water for jet propulsion; also serves as an outlet for ink and waste products.
Intestine: Tube-like structure where digestion occurs; nutrients from food are absorbed here.
Penis: Male reproductive organ; plays a key role in the transfer of sperm to females.
Ink Sac: Organ that produces ink, which can be released as a defense mechanism to obscure vision and allow escape from predators.
Gill: Respiratory organ responsible for gas exchange; allows the squid to take in oxygen from water and release carbon dioxide.
Mantle: Main body wall that encases the squid's internal organs; helps with locomotion and protection.
Branchial Heart: Specialized heart located near the gills; pumps oxygenated blood to the rest of the body.
Vena Cava: Major vein collecting deoxygenated blood from the body and returning it to the branchial heart.
Testis: Male reproductive gland responsible for producing sperm and male hormones.
Cecum: Part of the digestive system; aids in nutrient absorption and is involved in processing food.
Fin: Thin, membranous extensions along the body; assist in stabilization and steering during swimming.
