Wonderful Deep Sea Worm

　　Some of these weird insects have no anus, some have teeth like a grain harvester, some look like a Christmas tree, some have a body length of 55 meters, and some have no heads. Who are they?
　　In the depths of the ocean, there is a strange kind of animal. Some of them do not have an anus, and some have so powerful jaws that they can cut inadvertently passing fish into two pieces. They are hundreds of millions of worms in the deep sea. These strange creatures are more interesting or scary than your dreams.
　　Worms living in hot spring vents.
　　In 1988, when American scientists were studying the hot spring vents in the Pacific Northwest, they discovered a group of setaria worms called sea scale insects. The teeth of this kind of worms looked like the beaks of a strong parrot. A combination of lawn mowers. At first, scientists thought that sea scale insects were ferocious carnivores, using their powerful teeth to bite their prey and tear it into pieces. However, the function of the sea scale insect’s teeth is more like a grain combine harvester, clattering to “reap” the dense bacterial “carpet” and single-celled organisms living near the hot spring vents. Their terrible mouth can be turned inside out, which makes it easier to catch prey. Fortunately, they are only 2 to 3 cm long and cannot harm humans.
　　In deep-sea hot springs where light cannot reach at all, the ecological communities near sea scale insects cannot obtain energy through photosynthesis. Therefore, they can only obtain the required substances from the chemical process of the hot springs. Therefore, in addition to harvesting prey, sea scale insects live a simple life, feeding on the symbiotic bacteria that live between their back scales. The symbiotic bacteria can use the minerals in the hot spring to provide nutrition and energy for the sea scale insects.
　　Worms with Stinger
　　tropical regions of the Atlantic Ocean and the Mediterranean Sea where the majority live in a very friendly kind of worm – fire thorn insect. This creature has a large body 15 cm long, and their back is like a flat plate, but along the side edges of the flat plate, long “bristles” grow. They look like cute pets with “big beards”, but you only need to touch them lightly to know that their names are not in vain.
　　Divers who have been in close contact with fire spurs will have symptoms of skin rashes: hands become red and swollen, tingling sensations come intermittently, and the burning sensation on the hands lasts for several days. In severe cases, divers may even feel dizzy, nauseous, and painful. The mystery lies in the slender bristles distributed on both sides of the fire thorn insects. These bristles are hollow, and the middle is actually full of strong neurotoxin channels. The pipes are easy to break and will break and release venom as soon as they are touched. Therefore, these self-contained weapons have become one of the tools they use to expel predators.
　　Super long worm
　　In 1864, after a violent storm, a long black worm was washed by the sea on the coast of St Andrews, Scotland, England.
　　A local natural historian began to measure the worm, which was not an easy task, because the worm kept constricting and constricting together. Finally, natural historians determined its length-no less than 55 meters! At that time, this huge banded worm was considered one of the longest animals ever measured by humans. Because even the blue whale captured in the Falkland Islands in the South Atlantic in 1904 is only about 33 meters long.
　　It was identified that this worm belonged to a strange marine animal-the worm of the phylum Neoforma. They generally live in the ocean. They are very long and thin, and their body surface can secrete very acidic mucus. There are many tissue cells between their intestines and body walls, which can store food. Therefore, they are very resistant to starvation.
　　Nebula is a carnivorous animal that catches prey with long, sticky snouts. The kiss is located in a special cavity on the back, almost more than half of the body length. When preying, when the prey is not ready, the snout of the worm can suddenly stretch out, quickly entangle the prey and draw it into the mouth. Some worms have needles on the snout to enhance their predatory ability.
　　The most ruthless of worms
　　when it comes to the most ruthless underwater predators, have to mention Bobby worms.
　　In early 2009, many fishes in the Newquay Aquarium in the United Kingdom disappeared without warning, leaving only a few scattered scales on the bottom of the aquarium. The staff believed that the fish was stolen by a thief, but from the surveillance video within 2 months, there was no trace of the thief’s entry and exit, so the staff decided to dismantle the aquarium.
　　The remaining fish were removed, and the staff began to drain the water. At that time, the staff saw a 1-meter-long Barbie, which is a fish killer hiding in the dark.
　　Barbies are one of the longest sety worms in the ocean and one of the most ferocious and cruel carnivores. They can grow up to 3 meters long and lie on the bottom of the sea or between the gaps in rocks in the shape of an S, waiting for prey to come. Whenever fish pass by their hiding place, they launch a “rocket”-a pair of jaw bones sharp like scissors. Due to the rapid attack of Barbies, some prey are often cut instantly or even split into two. Humans can also be bitten if they are too close.
　　When hunting, barbies open their big mouths and bite their prey hard, but to make the prey completely immobile, the barbies need to inject a large amount of toxins into the prey before they eat the delicious food leisurely.
　　Like a worm Christmas tree
　　Christmas tree decorations insects like tropical ocean gatherings. Coral reefs are very common in tropical and subtropical oceans, and Christmas tree worms build small tubes in corals to settle down, stretch out their unique tentacles, and float in the sea. The tentacles are long, twisted, and have thin filaments that can be used to filter tiny, edible particles in water. The tentacles and filaments form a large, colorful crown shaped like a Christmas tree.
　　Christmas tree worms are setaria worms and the largest group of animals in the ocean, with more than 10,000 known species. Christmas tree worms play an important role in the ocean, partly because they are the most important converters of organic matter. They can filter water and look for organic particles, otherwise these organic substances will be wasted.
　　Tail worms will walk
　　every year from October to November, millions of 30 cm long “flatworm” from the depths of the Pacific Ocean to float one after another, hundreds of small South Pacific island residents have come to seize They, treat them as delicacies.
　　The first biological scientific description of this kind of insect was in 1847, when scientists named them the sandworm. Strangely, scientists discovered that they have no heads! After 50 years, scientists realized that the head of the sandworm lives on the bottom of the sea, while its own tail is participating in a large-scale mating game. When the mating season comes, the tail of the sandworm will fall off on its own and become a separate individual, and the worm’s tail contains egg and sperm cells. This special tail is called the Reproductive Festival, and it has an eye left, allowing it to swim freely to the bright sea, until it reaches the place where all the Wormtails gather and starts a Wormtail carnival. And their heads left on the seabed will re-grow a tail.
　　Non-fecal worms
　　In the 1970s, scientists discovered a series of hot spring vents on the seabed in the southeastern United States. The temperature there is as high as several hundred degrees Celsius, and water with rich minerals flows out of the seabed. In addition, they also discovered a whole new ecosystem. One of the main creatures is 3 meters long, red and white worms, they live in large-scale gathering around the spring.
　　Worms live in long tubes, and their hairy mouths rippling in hot water. These hairs appear red because of the high hemoglobin content, which makes it easier for worms living around hot springs to absorb oxygen. The tube surrounding the worm is composed of sugar and protein, which protects the worm’s soft body from high-temperature fountains and high-strength chemicals.
　　The internal anatomy of a worm is as unusual as the external structure. The vegetative body of the tubular worm is a special organ that contains bacteria. The bacteria and the worm are symbiotic. The bacteria can convert the oxygen absorbed by the worm and the minerals in the hot spring into energy. One of the strangest characteristics of worms is that they lack an opening in their body to expel waste. In fact, they do not produce a lot of waste, and the little waste produced is stored in the body-that is, they have never defecate.
