There are many animals in the world that people have never seen, such as vampire squid. Just by looking at the name, we know that it belongs to our common squid and is similar to octopus. Like the name of the vampire squid, this animal is very similar to the horror creature in the horror movie. It has two big things like fins and looks like big ears. The body is more like a jellyfish, showing a transparent shape. Researchers speculate that vampire squid may be the ancestors of squid and octopus.

First, the biological evolution of vampire squid

Vampire squid is similar to squid and octopus, but it is not all the same. Vampire squid is presumed to be the ancestor of octopus and squid. It moved from shallow sea to deep sea hundreds of millions of years ago to avoid the pursuit of natural enemy dinosaurs, so the appearance of vampire squid has not changed for hundreds of millions of years.

Because it moved to the deep sea early, the vampire squid adapted to the deep sea environment very early. Although there is no change in appearance, the lack of oxygen inside leads to changes in blood, and the body will glow in the deep sea to warn some creatures not to get close to themselves.

Second, the living habits of vampire squid

Unlike ordinary octopus and squid, vampire squid has no ink sac. The tentacles of vampire squid have teeth as sharp as nails, so they are called vampire squid. A pair of tentacles can be extended to a thin body, and the researchers found that the longest can be extended to twice the length of the body. Vampire squid rely on this pair of tentacles and other tentacles to cooperate to catch prey. Once encountering difficulties, the vampire squid will cover all its tentacles to form an aggressive protective cover to protect itself.

There are still many creatures in the world that existed since ancient times. There are many animals similar to vampire squid. These creatures play a very important role for scientists to study the world environment and ancient events. However, people still need to pay attention to protect them, because these species are also very easy to become extinct, so we should also pay attention to protecting organisms while studying.
