SQUID DISSECTION PREPARATION! 5 th Grade Ms. B
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
Male or Female? Females: – Eggs = yellow in color – Nidamental glands: large, oval white organs in the middle of the cavity

Squid Dissection. Taxonomy of the Squid Kingdom: Animalia Phylum: Mollusca Class: Cephalopoda Order: Teuthida Family: Loliginidae Genus: Loligo Species:
SQUID DISSECTION. Position your squid Place squid in tray, with its dorsal side facing up.
Cephalopods: head/foot. Kingdom: Animalia Phylum: Mollusca Class : Cephalopoda.
Phylum Mollusca Examples: Snails, slugs, squid, clams, octopus, and scallops.
1. Label external anatomy. Place the squid with the dorsal (back) side up in the dissecting pan (fin side up). Use the hand lens to examine the suckers.

Hello! Welcome to Mr. D’s Virtual Dissection Lab. While you may not be able to participate in the lab, I hope you will find this quick exploration into.
Mollusks Chapter 27. Mollusk characteristics Soft-bodied animals with an internal or external shell Trochophore: free-swimming larvae stage Body plan.
Phylum Mollusca. Mollusks 100,000 species “soft bodied animals” Eumatazoans, bilaterally symmetrical, triploblastic coelomates Mostly marine, some freshwater,
Phylum Mollusca, Class Cephalopods Cephalopods (Class Cepahlopoda) are a group of molluscs that include squid, nautilus, cuttlefish and octopus They are.
Mollusca is the second largest phylum in the animal kingdom. In Latin Mollis means soft. The animals of this phylum have a soft body. Hence they are.
