When it comes to vampires, it is estimated that many people will feel scared, but at the same time they will have a lot of interest in it. Anyone who has seen a movie or TV series about vampires knows that vampires are creepy supernatural creatures.
They are afraid of the sun and live by sucking blood, and the sharp fangs when they suck blood make the people who see it fearful. This is basically the stereotype that vampires give people.
Returning to our real life, this creature obviously does not exist on land, otherwise it is estimated to cause social panic. However, in the deep sea area of more than a thousand meters of the vast ocean, there is such a creature, they are called sea vampires. This creature is particularly frightening in both appearance and name, it is a ghost grub.
Ghost grubs look like both squid and octopus, and many people can't tell what type of marine creatures the ghost grubs belong to. In fact, the ghost grub can be said to be the ancestor of the two, because tens of millions of years ago, squid and octopus had a common ancestor. So, is the ghost grub known as the vampire really a real vampire monster, as its name suggests?
<h1 class="pgc-h-arrow-right" > the historical evolution of ghost slugs</h1>
The ghost grub is an ancient creature that has survived for tens of millions of years, which means that it is contemporary with dinosaurs. Although it is somewhat similar to squid and octopus, it is actually a certain difference.
For example, the octopus has 8 tentacles, the squid has 10 tentacles, and the ghost slug has 8 tentacles like the octopus, but it has two large flesh fins, which is not available to octopuses. For the squid, this is the same as the ghost slug.
In addition, ghost grubs do not carry their own ink sacs like octopuses and squid. From this point it is also shown that the ghost grub may have been the ancestor of squid and octopus in ancient times. However, after tens of millions of years of evolution, the ghost slug has continuously evolved to become what it is now.
In addition, according to research surveys, the 80 million-year-old ghost grub was not active in the deep sea, it was active in the shallow sea, and it was three times the size of the current one, that is, about 1 meter long. But in order to escape the predators, the ghost grub had to gradually move to the deep sea.
Various research results show that the ghost grub is inseparable from the octopus and squid, so many people have a consensus later: the ghost grub is the ancestor of the octopus and the squid.
<h1 class = "pgc-h-arrow-right" > peculiar body structure</h1>
Why is the ghost grub called a vampire, and does it really suck blood? Not. It is called a vampire because of its supernatural appearance and strange body structure.
In the early 20th century, marine expeditions came into contact with a very strange creature during their survey, which was described as having "black-red skin, ivory teeth, and large blood-red eyes." Such a description of appearance reminds people of vampires, and coupled with its survival of tens of millions of years, it further confirms the claim of deep-sea vampires.
The speed of the ghost slugs active in the ocean is very fast, and each movement can reach the distance of two bodies per second, that is, about 3 meters. Relative to humans, the average walking speed of humans is about 1.5 meters per second, which shows the speed of ghost slugs.
In addition, the body of the ghost grub is very soft, and it can perform difficult movements from multiple angles. The ghostly grubs that appear in many deep-sea probes are often 360° free rotation, front flip or backflip, which feels like playing acrobatics.
The ghost grub also has a very magical light emitter on its body, why is it magical? Because its light can be retracted freely, its brightness is controlled autonomously. The ghost grub will attract the attention of its prey by lighting itself up, but it will also invite itself to kill.
When danger comes, the ghost grub will control the brightness of the light and gradually dim the brightness to fool the predator into thinking that the prey has run away, and finally stop glowing and successfully escape. I have to say that the ghost slug is indeed a very clever creature in the deep sea.
In addition, the most similar thing between a ghost grub and a vampire is the row of fangs on the tentacles. They don't use these fangs to attack predators, but instead, when in danger, they raise all their tentacles to wrap themselves up, and the ghost grubs are like wearing a nail-covered armor to keep the enemy from being eaten.

Now that it is known that the ghost grub does not suck blood, what does it eat? Not only does the ghost grub not suck blood, it is also a hard-working marine cleaner who comes alive.
Although the ghost grub survives on the seabed at a depth of more than 1,000 meters, the latest research shows that their flexible figures can still be found on the seabed at a depth of more than 4,000 meters.
They do not feed on living animals, and their main food sources are plants floating in the upper layers of the ocean and residual biological material in the middle layer. For example, the corpses and excrement of some marine creatures and so on. In this way, the ghost grub not only does not harm marine animals, but also acts as a garbage disposer in the ocean.
Marine life is strange and strange, especially the strange species of ghost grubs, which refresh scientists' understanding over and over again. Although the results of deep-sea exploration are not perfect enough according to the current scientific exploration instruments, it is believed that in the near future, with the continuous progress of science and technology, human exploration of the ocean will be better and better.
