Octopus and cuttlefish do have a lot of similarities, but they are two different creatures, not the same, they are different in many ways. Specifically, the following points are their differences:
1. Different families: Octopus and cuttlefish belong to different families. Octopus belongs to the octopus family, and cuttlefish is what we often call "squid", which is a creature of the cuttlefish family.
2. Different numbers of arms: Although octopus and cuttlefish may have some similarities in appearance, for example, they both have arms, but if you look closely, you will find that their arms are actually different. The octopus has eight arms, while the squid has 10 symmetrical arms, two of which are relatively short and eight of which are relatively long.
3, food is different: octopus and cuttlefish eat food is also different. Octopuses feed mainly on crustaceans and plankton in the ocean. In addition to eating crustaceans, cuttlefish can also eat many fish and a variety of mollusks.
As mentioned above, octopus and cuttlefish are two different creatures, they can not be confused. In addition to the differences in the above three aspects, the number of brachiopods and food, there is another important difference, that is, the difference in IQ. In contrast, octopuses are more intelligent, and biologists have done a lot of research on intelligent octopuses and found that they can distinguish themselves from other animals and use what they know. But the cuttlefish's brain is relatively undeveloped and not as smart as the octopus.
