Cephalopod Research Paper

There are many marine animals that are classified as cephalopods. A cephalopod is an aquatic animal that has bilateral body symmetry, a set of tentacles or arms, and a distinctive head. Cephalopods are the most intelligent and the most mobile of all the molluscs. There are many types of cephalopods: differing in size, shape, and their living habits. Two types of cephalopods are squid and octopi. Although, squid and octopi are both classified as cephalopods, they have many differences. Squid and octopi differ in physical features, living environment, lifespan, behavior, and much more.

The squid has slightly different physical features than the octopus. A squid has eight arms, separated in pairs of two and attached at the bottom of its triangular-shaped head. They have two eyes, one on either side of its head. These eyes are like a camera lens; by positioning the lenses in their eyes, they can focus on something. They cannot see color, but they can see in the dark. Squids have eight arms and two tentacles that are longer than the arms. Suckers and sucker rings, also known as hooks, cover the bottom of the squids' arms and tentacles. Squids also have two fins on the side of their head, mainly used to steer while
They share many of the same features, lifestyles, and behaviors. The squid and the octopus share similar mating styles as well as the time of passing. Both the male octopus and the male squid die shortly after mating, while both the female octopus and female squid stay alive to care for their eggs, then pass. The squid and octopus both have three hearts, a systematic heart, and two branchial hearts that surround the systematic. Although, they have many similarities they have a lot of differences. Differing in where they live, physical features, lifespan, and more. Both are amazing and intelligent
