Bugs are creatures that many people can't accept, and even if they don't bite, they feel disgusting.
In general, bugs live in the soil. However, the worm we are talking about today lives in water, and this is the Bobbitt worm.

As early as the 19th century, biologists were aware of the existence of such creatures. It wasn't until more than 20 years ago that an underwater photographer officially named it Bobbitt Bug, which is also its more popular name. And its scientific name, called Eunice aphroditois, Chinese translates to squamous serpentine silkworm.
In fact, it is called Bobbitt or Sycamore, but it is not an insect, but a distant relative of insects. They belong to the same phylum arthropods, but insects are separate insects, while Bobbitts are a species of polychaete.
This creature usually lives in warm seas and lives at ocean depths between 10-40 meters.
In the picture of the Bobbitt worm, we can't see its size. In fact, this creature is relatively large, at least compared to insects, or much larger than we think.
According to observational records, the length of Bobbitt worms is usually more than 1 meter, and the longest can reach 3 meters. However, they are not stout, the body is relatively slender, generally only about 2.5 cm wide.
Their bodies have a metallic sheen and look very gorgeous. Inside the beautiful body, though, hides the face of a terrifying predator.
The feeding organs of Bobbitt worms are not the same as other creatures, they have a "pharynx", which is usually stored in the body and will turn out when eating. At the end of this organ, the bobbitt's sharp jaw is ready to strike. They usually hide in the shadows, through surprise attacks and strong impulses, cut off the prey, very brave.
Once they have caught their prey, bobbitts hide back in their original rocks or sand and quietly taste the food.
What's even more frightening is that Bobbitt not only has a powerful jaw, but it also carries poison. The hair covered by Bobbitt worms is described to be toxic. Any creature that accidentally scrapes it will be paralyzed.
A few days ago, when a netizen in the United States was raising fish at home, he found that the fish in his fish tank always disappeared inexplicably. Until one day two years later, the number of polyps and fish in his fish tank was decreasing. This netizen really couldn't stand it, and began to carefully observe the dynamics in the fish tank.
As a result, he was shocked by the picture in the fish tank. In the sand below the fish tank, a huge insect up to one meter long suddenly sprang out, and at once it grabbed the fish in the fish tank and disappeared into the sand.
The netizen published the video online, which instantly detonated the internet, quickly received 173,000 views, and let the world know about this terrifying creature.
In 2009, in an aquarium in the United Kingdom, many fish were inexplicably cut into two pieces. After a long period of observation, they found a Bobbitt worm up to 1.2 meters long. According to the aquarium staff, the Bobbitt worm was most likely lurking in the coral before and then being released into the aquarium.
The largest Bobbitt worm found so far was discovered in 2009 in the Seto Fishing Port in Japan's Kushimoto Marine Park, and at the time of its discovery, the Bobbitt Worm had grown to 3 meters long and weighed 0.5 kg (it can be seen that this creature is really "thin"), with a total of 673 links on the body.
Fortunately, this terrible creature lives in the ocean, and we can hardly see it. It is hard to imagine that when the American netizen found that there was such a monster in his fish tank, his heart broke down...
