Many people will not distinguish between octopus and squid, they do have similarities, such as their ability to jet ink and so on. However, in fact, they are not a kind of organism, the difference between them is relatively large. The following are their specific differences:
1. Differences between families and genera: Octopus and cuttlefish are two different organisms of different families and genera, which are very different. Specifically, octopus is an octopus genus, octopus family organisms; The cuttlefish is a cuttlefish genus, cuttlefish family organisms.
2. Appearance difference: The appearance characteristics of squid and octopus are also different. For example, the number of their wrists is different, squid has 10 wrists, left and right are symmetrical, of which 8 are relatively short, 2 are relatively long, their specific role is different. Octopuses have a total of eight wrists, all of which can be contracted freely.
3, food differences: octopus and cuttlefish feeding habits also have some differences. Octopuses mainly eat crustaceans, such as shrimps, crabs and so on, and may also eat plankton in the water. Squid can eat more food, in addition to crustaceans, but also eat fish and some mollusks.
4, IQ difference: Octopus and squid IQ is also different, compared to the two octopus is more intelligent, they can even be said to have "conceptual thinking", the way of thinking will be more complex.
The above has been introduced, IQ is one of the differences between octopus and squid, the two are still more intelligent octopus. Octopus brains will be more developed, they have the ability to use their known information to solve relatively complex problems. Although the nervous system of cuttlefish is relatively developed, but their brain development is not perfect, so to a large extent are judged by experience and feeling.
