Key Terms Stomach Ink sac Esophagus Gill Heart Gonad Anus Pen
Key Terms Arms Tentacles Nidamental Gland Buccal Bulb Chromatophores
Buccal Bulb: muscle that operates the beak
Radula: rows of teeth
Squid Anatomy Chromatophores: spots change size to change the squid’s color for camouflage
Fins: Help squid change direction when swimming
Mantle: the main part of the squid’s body that covers its internal organs
Pen: feather-shaped internal structure that supports the squid’s mantle and stabilizes the squid for swimming
Stomach: digest food
Ink Sac: defense mechanism
Ink: pigment melanin which artists refer to as “sepia ink” Octopi = black ink Squid = blue-black ink Cuttlefish = brown ink
Eyes: ability to see as well as people!
Have 8 arms and 2 tentacles
Arms vs. Tentacles Arms: short, rip apart prey and stuff it into the mouth Tentacles: long and have suckers on the end shoot out to capture prey
Suction cups: help squids hold onto food and act as “taste buds”
Gills: absorb oxygen from water
Beak: mouth resembles a bird’s beak
Gonad: reproductive organ males = white in color females = clear
Siphon: a tube that squirts out water so that the squid moves like a jet airplane
