Virtual Squid Dissection

Virtual Dissection Lab 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 the world of one of the coolest cephalopods fun!!

Please watch the following video. It will give you a glimpse into the world of the Squid • Wait for the play button to appear

Squids Info! The Squid is an invertebrate (animal without a backbone) that swims in the oceans. This mollusk is closely related to the octopus. Squid can change the color of their skin to mimic their environment and hide from predators. Squid are soft-bodied organisms. They are classifieds as Phylum: Mollusk, Class cephalopods. They move by squirting water from the mantle through the siphon, using a type of jet propulsion. When in danger, squid squirt a cloud of dark in order to confuse their attacker and allow the squid to escape. Squid reproduce by releasing eggs into the water. Some squid eggs are free-floating, others are attached to seaweed or to the ocean floor.

• Anatomy: Squid range from 1 to 60 ft (0. 3 to 18 m) long. The biggest squid is the Giant Squid (Architeuthis). Squid have a large mantle/head (with a large brain), eight arms with suckers, two longer feeding tentacles, a beak, a large head, two large eyes, and two hearts. Their large eyes are very similar in structure to people's eyes. They breathe using gills. • Diet: Squid eat fish, crustaceans (like shrimp), and other squid. These fast-moving carnivores (meat-eaters) catch prey with their two feeding tentacles, then hold the prey with the eight arms and bite it into small pieces using a parrot-like beak. The esophagus runs through the brain, so the food must be in small pieces before swallowing. • Predators: Many animals prey upon squid, including many sharks and other fish, some whales, squid, and people. • Classification: Kingdom Animalia, Phylum Mollusca, Class Cephalopoda, Order Teuthoidea, Families Loliginidae, Sepiolidae, and Architeuthidae.

Squid Dissection • Now you can watch a squid dissection. Just follow along with the instructor and check the boxes as he proceeds through the external and internal dissection. • The tour of the external anatomy will look at the dorsal and ventral side • Put a check mark for each part as they are identified by the instructor on your worksheet • Have Fun!! Make sure your name, period, date and your teacher’s name is on the lab sheet
