  1. SQUID DISSECTION PREPARATION! 5th Grade Ms. B

  2. Key Terms • Stomach • Ink sac • Esophagus • Gill • Heart • Gonad • Anus • Pen

  3. Key Terms • Arms • Tentacles • Nidamental Gland • Buccal Bulb • Chromatophores

  4. Buccal Bulb: muscle that operates the beak

  5. Radula: rows of teeth

  6. Squid Anatomy • Chromatophores: spots change size to change the squid’s color for camouflage

  7. Fins: Help squid change direction when swimming

  8. Mantle: the main part of the squid’s body that covers its internal organs

  9. Pen: feather-shaped internal structure that supports the squid’s mantle and stabilizes the squid for swimming

  10. Stomach: digest food

  11. Ink Sac: defense mechanism

  16. Suction cups: help squids hold onto food and act as “taste buds”

  17. Gills: absorb oxygen from water

  18. Beak: mouth resembles a bird’s beak

  19. Gonad: reproductive organmales = white in colorfemales = clear

  20. Siphon: a tube that squirts out water so that the squid moves like a jet airplane

  21. Male or Female? • Females: • Eggs = yellow in color • Nidamental glands: large, oval white organs in the middle of the cavity

  22. Males:
