For example, the Grimpothethis or dumbo octopus belongs to the former body shape category. Octopus live throughout the ocean but prefer areas of coral reefs and among the seed. Some live in deeper areas of the ocean, including abyssal depths. Like with squid, there are a few species that change color while undergoing the courtship and reproduction process. With the giant Pacific octopus, the female lays strings of eggs in a crevice and guards them for months, around a total of days.
Octopi plural for octopus have more varied body shapes, are generally smaller, have eight arms, and have rounded heads. Squid, on the other hand, have ten arms, have two fins on top of their heat, and a rigid backbone.
Calamari is squid but is often confused with octopus. The two animals are both eaten, although squid is more common. Squid generally grow to be larger than octopi, between 60 centimeters to 20 meters long. Octopi, on the other hand, only reaches between one centimeter and nine meters long.
The largest squid in the world is the giant squid which can grow up to forty-three feet or thirteen meters long. Squid are generally believed to be the less intelligent of the two species.

Squids, on the other hand, tend to live in schools or solitary lives. Some squid species live in schools when younger then become solitary creatures when fully grown. Unlike octopuses, squid prefers living in the open ocean when they can hunt for other fish. They can be found in shallower waters to the darker depths of the sea.
Since these two creatures have almost similar anatomies, their hunting behavior and techniques both resemble one another as well as vary to some degree:. Since squid tends to swim in the open ocean mostly, their hunting techniques involve heavy use of their tentacles. They make good use of the two extra-long tentacles with suckers and teeth to reach out and grab shrimp and other fish, which they then eat in chunks. Once completely helpless, octopuses slather their prey with saliva, which dissolves and loosens the meat before using their mouths and beaks to rip and tear the meat from said prey.
They prefer to hunt for bottom-dwelling crustaceans because their soft bodies are vulnerable to predation. This is yet another key difference between octopuses and squids. Considering how small these two species can get, they both have decent lifespans, with octopuses living anywhere between 1 to 3 years on average and squids having a life expectancy of about nine months to about five years.
Perhaps the biggest similarity between the two, both creatures tend to die after mating. Octopuses are semelparous animals that only reproduce once and then perish. In octopuses, as soon as the female lays a clutch of eggs, she simply stops eating and slowly wastes away. She dies by the time the eggs hatch. Also, in a rather macabre twist, female octopuses tend to kill and eat their mates. Squids also do the same thing except for kill and eat their mates.
