What is the difference between a squid and an octopus?

Squids and octopuses are both members of the cephalopod family and share many similarities. However, there are also several key differences between the two.

One of the main differences between squids and octopuses is the shape of their bodies. Squids have elongated torpedo-shaped bodies, while octopuses have bulbous, rounded bodies.

Another difference is in their arms. Squids have 10 arms, while octopuses have eight. Squid arms also have two rows of suction cups, while octopus arms have only one.

Squids are also generally larger than octopuses, with some species growing up to 60 feet long. Octopuses, on the other hand, tend to be smaller, with most species averaging around 8-12 inches in length.

In terms of behavior, squid are more social than octopuses and tend to congregate in large schools. Octopuses, on the other hand, are solitary creatures and prefer to be alone.

Overall, while squids and octopuses share many similarities, there are several key differences in their physical characteristics and behavior that set them apart.
