Many people mistakenly believe that an octopus and a squid are the same kind of creature. In fact, they are not the same kind of creature. There are quite a few differences between them:
1. Different families and genera: The families and genera of octopuses and squids are different. Squid belongs to the family Loligo, and octopus to the family Octopodidae. Squid is a squid, and octopus is an octopus, the two are very different.
2. Appearance: Octopus and squid are different in many aspects of appearance characteristics. For example, their body shape, octopus body is oval, relatively short, squid body is more slender, overall is long cone. For example, the division between the head and body of octopus is not easy to distinguish, but the head and body of squid are more obvious.
3. Different living environments: Octopuses live in relatively deep water. They adapt to environments with relatively high salinity. In the case of low salinity, they may not adapt or even die. However, squid live in the middle and upper layers of water, so the salinity is relatively low.
4, food is different: the two main food is different. Octopuses eat mainly crustaceans, and sometimes some plankton in the water as their own food. Squid mainly eats other small fish, such as sardines, silversides and so on.
octopus and squid compared to octopus, or more intelligent octopus. Octopus is one of the more intelligent animals, much more intelligent than squid. They can distinguish themselves from other animals and are well aware of their abilities. They also use the information they already know to make decisions, which has been shown in some experiments.
