Squid Dissection
Description
In this lab, we dissected a squid. We received a squid in an airtight bag, cut it open, and let the revolting smell enter our nostrils. We cut it open and removed one gill to observe. We determined the gender, a girl, and gave the squid a tattoo with its own ink.

Tray
Pins
Conclusion/Analysis
We dissected the squid to find out some new things about it. I found out that squids have feeding tentacles which are the longer ones.
Ecology
Mollusks, also known as squids, are eaten every day and eating every day. They feed on plants, animals, and filter algae. They have tentacles, but two long feeding tentacles, which they use to grab their prey. They eat their prey with a small beak.
Comparative Structure & Function
Squids have most of the different kinds of systems, unlike other phyla. They have a complete digestive system, an open circulatory system, breathe through their gills, use kidneys for excretion, and sexually reproduce. They have bilateral symmetry and three germ layers. Their level of organization is at organ level. They also have limited cephalization.
