What does a giant sea spider look like? What do you usually eat?

In the colorful world, there are not only many cute and beautiful creatures, but also some strange species that humans have never seen or heard of, such as giant sea spiders.

It is said to be very ferocious and huge, so what does a giant sea spider look like?

The giant sea spider is not a spider, but the largest crab in the world, the body length can reach 3 meters, and at the same time has 8 long legs and a snout tube structure, they are lurking at the bottom of the sea 2000 meters "ghosts", what is more strange is that these giant sea spiders breathe in a very special way, that is, as it grows and the size of the organism increases, their legs will appear more holes, so as to absorb oxygen faster.

Giant sea spiders have also been studied and the effects of different water temperatures on giant sea spiders have been analysed through this test at a variety of different water temperatures. Finally, it was found that giant sea spiders can normally survive in water spaces between minus zero and 9, which also made the scientists.

Their size was found to have a direct impact on warm waters.

Giant sea spiders are generally hydra.

It feeds on bryozoans, and sometimes it also eats starfish, corals, small fish, and shrimp, so to speak, almost anything. They live mainly in the waters of the Japanese coast in the North Pacific Ocean at depths of 300-400 meters, and because these areas are the areas with the fewest large predators, sea spiders can be protected from predation, and the sea water here tends to be high in salt and oxygen, so sea spiders are huge.

Although there are few large predators in the environment where sea spiders live, there are also relatively few species here, so there are not many things for sea spiders to hunt, and in order to survive, giant sea spiders have evolved a very strong stomach function, and even if there are no fish to hunt, they can survive by eating coral.

In addition, because of the fleshy nature of giant sea spiders, humans are not suitable for consumption. Therefore, it also avoids a large number of human hunting.

The giant sea spider is a giant crab, so its appearance is very similar to that of a crab, and it mainly feeds on water locusts and seaweed, and will also eat some starfish, small fish and other foods.

The giant sea spider is the largest crab in the world. With a body length of 3 meters, this creature lives mainly in the waters of 300 to 400 meters deep off the coast of Japan in the North Pacific Ocean, where it eats almost anything.

Giant sea spiders can't be eaten.

Giant sea spiders, this sea spider is very large, with legs up to 25 centimeters long, which is simply terrifying. Generally speaking, this species of sea spider is relatively small, and this giant sea spider may be suffering from polar megatonia, that is, because the special environment of Antarctica has made this creature larger.

The sea spider is actually a relatively primitive marine arthropod.

Although they are not real spiders, they may have the same roots as the spiders on land, and the sea spider appeared on the earth hundreds of millions of years ago and is one of the most primitive creatures in the ocean.

And the size of sea spiders is generally about 5 6 mm, but scientists.

A giant sea spider was found on the bottom of the dark and cold sea floor of Antarctica, with the longest leg reaching 25 centimeters, which is 50 times larger than the original! This giant sea spider has 8 long legs and a snout tube structure. This is the largest sea spider known to man.

But such large creatures are only found in Antarctica, not only sea spiders, but also some sea creatures that live in the same place as giant sea spiders.

The size has also become larger. This condition is extremely rare, and scientists believe that it is the cause of Polar Mega Sickness.

Polar megalogeneity is just a hypothesis that some sea creatures will become much larger than others, and there is no scientific explanation for this phenomenon. This kind of biomagnification phenomenon has only been found in the North and South Poles, so it is called "polar megalophoia".

1. Overview of spider feeding habits

Spiders are considered the king of killers, and their eating habits are related to the type and size of their prey. In general, spiders are able to hunt insects that are smaller than their size, such as mosquitoes, flies, bees, etc. Some of the larger spiders are capable of preying on larger insects such as scorpions, crickets, locusts, and even small birds and bats.

Spiders use their webs to catch their prey, inject them with venom and eat them.

Due to the small size of the spider body and the low amount of energy required, the number of prey is not necessarily large, but they play an important role in maintaining the ecological balance.

2. Spider food**

Spiders that actively hunt, such as tarantulas and hunting spiders, usually build webs or wait for their prey to arrive, and then quickly attack to capture them. Spiders that suck nutrient solutions digest the digestive juices secreted by their own salivary glands into prey and absorb nutrients.

3. Spiders know the nutrients needed by spiders

Spiders have relatively low nutrient requirements and mainly need proteins and carbohydrates that provide energy. In addition, they also require a certain amount of vitamins and trace elements to maintain health. Spiders have a relatively simple diet**, which means they need to eat enough food to meet their nutritional needs.

4. Food diversity and environmental adaptability of spiders

Despite the fact that spiders have a relatively monotonous diet, they still have strong environmental adaptations and food diversity. Spiders can adapt to different foods in different environments**, such as spiders in the desert can adapt to eating special foods such as sand scorpions. In addition, there are many types of spiders, and different species of spiders also have their specific food**, which makes them have a certain variety of foods.

Name: Sea spider.

English] pycnogonum; sea spider

Aliases] is also called the all-legged worm, which resembles a spider, so it is called a sea spider.

Family: animalia.

Phylum: Arthropoda phylum Arthropoda.

Yamen: chelicerata

Class: pycnogonida

Arthropoda, a spider-like marine animal of the class Pycnogonida, also known as the class Pantopoda. They crawl on the bottom of the sea with their slender feet, and some can tread water. Most of them have four pairs of slender feet on four trunk segments.

The length of the tropical shallow water species is 3 mm (1 8 inches), and the deep water species is 50 cm (20 inches). The triangular mouth is at the end of the sniffing kiss. Adults feed on the fluids of mollusced invertebrates, or feed on polyps (cnidaria ) and bryozoans.

4 monocular, but deep-water species often have no eyes. The digestive and reproductive systems have branches that lead into the foot. Dioecious, in vitro fertilization.

The male carries the eggs on a pair of specialized feet until hatching. The larvae of many species parasitize cnidarians or mollusks. The nervous system and circulatory system are simple, the respiratory and excretory systems are not obvious.

There are more than 600 species, and a Jurassic fossil species is known. Sea spiders are sometimes referred to as whip scorpions.

This section] distribution area.

It inhabits the seashore and often crawls on seaweed or under rocks. There are not many species, but they are widely distributed and are found in almost every ocean.

This paragraph] morphological characteristics.

The body is five to six millimeters long and brown or yellowish in color. There is a mouth at the anterior end of the cephalothorax with four small bulges on it, on which there is a single eye. The abdomen is underdeveloped, with only a small protrusion.

cephalothorax with four pairs of long legs, ending in hooked claws; It has a pair of smaller chelicerae in front of it. There are 4 monocular eyes on the dorsal ocular process (oculife-rous tubercle). The thorax is distinctly divided into 4 segments, and the abdomen is very short, with a small unsegmented protrusion that follows the posterior end of the chest.

In addition to the pincers and tentacles, the male also has negative ovoid feet and 4 pairs of long feet. The long and blind tubes of the intestine extend into each foot, and the gonads are 1-5 pairs, with the female opening at the second segment of each step and the male opening at the second segment of the fourth step. There is a heart, no respiratory organs and no excretory organs.

The sea spider looks a lot like a normal "blind spider", with long thin legs and a short torso. Although they appear to have some connection to spiders on land, sea spiders also have some unique anatomical features – including a special diaphragm on their heads that is used to transport eggs – which means that perhaps sea spiders should have their own branch of the spider arthropod "family tree".

There are no spiders on the bottom of the sea, are there spiders on the bottom of the sea in junior high school mothers? There are no nautical miles.

The sea spider is not a spider, it is an animal called a parapod, because of its similar appearance to the spider, it is called the sea spider, and the sea spider mostly inhabits the seashore, the distribution range is relatively wide, in addition, the sea spider usually crawls on the bottom of the sea with slender limbs, some sea spiders can use their limbs to tread water, the body surface color is brown or light yellow, and the mouth of the cephalothorax is triangular.

Sea spiders are not spiders, it is an animal called allopods, because of its similar appearance to spiders, it is called sea spiders, and sea spiders mostly inhabit the seashore, the distribution range is relatively wide, and sea spiders can be seen in all oceans.

Sea spiders usually crawl on the ocean floor on elongated limbs, some are able to tread water on all fours, and their adults feed on mollusc invertebrate fluids, polyids and mosses, and their larvae are parasitic on cnidarians or molluscs.

The body of the sea spider is five to six millimeters long, the body color is brown or yellowish, the cephalothorax has a triangular mouth and four single eyes, and the abdomen is underdeveloped, in addition to the cephalothorax of the sea spider has four slender feet, and the end of the foot has hooked claws.

Sea spiders are not insects, because the definition of insects is that the body is divided into heads, chests, and abdomen, and has two pairs of wings, three pairs of legs, the head has antennae, and the shape of the life is changeable, etc., and the sea spider does not meet the above characteristics, so it does not belong to the insect, in addition, the head of the sea spider has a special diaphragm dedicated to transporting eggs, and the cephalothorax has hooked claws at the end of the long feet.

Sea spiders are similar in appearance to blind spiders, with elongated legs and a short torso, a special diaphragm on the head that transports eggs, a hooked claw at the end of the long legs of the cephalothorax, and one to five pairs of gonads, of which the female has an opening in the second segment of each foot.

The adults of sea spiders will suck the body fluids of mollusks, or eat bryophytes, and their heads have four single eyes, but sea spiders in deep water have no eyes, and the digestive and reproductive systems of sea spiders branch into the feet, which is characterized by in vitro fertilization.

The sea spider is not a spider in the sea, although it belongs to the subphylum Cheliceralopod of arthropods like spiders, and is similar in appearance to spiders, but sea spiders are more independent than spiders, in addition, sea spiders are tiny, only five to six millimeters long, brown or yellowish in color, and have four pairs of slender feet at the front of their heads, which can crawl on the bottom of the sea or tread water.

The sea spider is not a spider in the sea, although it belongs to the subphylum Chelicerae of arthropods like the spider, and is similar in appearance to the spider, the sea spider is more independent than the spider, and the sea spider has a wide range, often crawling on the seaweed or under the rocks.

Sea spiders have a body length of five to six millimeters, a brown or yellowish body color, four pairs of long legs at the anterior end of the cephalothorax, hook claws at the end of the long feet, and a pair of smaller chelicerae at the front end, and the belly of the sea spider is underdeveloped, and the thorax is distinctly divided into four body segments.

Sea spiders crawl on the bottom of the sea with slender feet, a few sea spiders can also tread water, mostly inhabit the deep sea at a depth of 3,600 meters, feed on mollusc vertebrates, and sea spiders are dioecious, fertilized in the body, in addition, sea spiders have hearts, but no respiratory and excretory organs.

The giant sea spider is the largest crab in the world. With a body length of 3 meters, this creature lives mainly in the waters of 300 to 400 meters deep off the coast of Japan in the North Pacific Ocean, where it eats almost everything, even starfish and corals. Cold temperatures, few predators, high oxygen concentrations in seawater, and longevity are all reasons for the large size of these species.
