Squid and octopus both belong to the cephalopod class, but there are some significant differences between them:
Squid belongs to the family Squid, whereas octopus belongs to the family Octopusidae. Although they both belong to the class Cephalopod, different families represent different branches of their evolutionary tree.
The body of the squid is usually more elongated, with longer tentacles, and the connection between the body and the tentacles is stiffer. Octopuses have shorter bodies and shorter tentacles, and the connection between their bodies and tentacles can be rotated flexibly.
Octopuses typically have much larger eyes than squid's eyes and are positioned closer to the top of their heads, which allows them to better observe their surroundings.
The squid has a jet hole located under its body that is used to spray ink to confuse predators or flee quickly. The octopus has two spray holes, which are located on both sides of the body.
Squid usually lose their shell during evolution, or their shell becomes very small. Octopuses, on the other hand, do not have shells, their bodies are soft and have no hard bones.
Octopuses are known for their high intelligence and problem-solving skills, while squid are generally shy and less active.
Squid and octopuses also have different feeding habits, with squid usually feeding on crustaceans and small fish, while octopuses are omnivores and feed on small crustaceans, fish, and mollusks.
These distinctions reflect their different biological and ecological adaptations and evolutionary pathways.
Squid belongs to the family Squididae, whereas squid belongs to the family Squididae. They differ in size, squid are usually larger, some species can reach more than 1 meter in length, while squid are smaller. The tentacles are also different, the tentacles of the squid are shorter and have 10, two of which are longer and are called brachiopods.
The tentacles of the squid are slender and the number is also 10, but the shape and length are different from those of the squid. Also, the shells of squid have degenerated, whereas squid do not have shells. Despite some similarities, squid and squid differ in details.
