Purple hermit crab.

It is a variety unique to the Japanese region and has a purple-blue, purple, or blue body color. Concave-footed hermit crab: It has a pair of bright red tentacles on its body and has a variable body color.

Strawberry hermit crab: bright red with white spots. Short-wristed hermit crab:

The body color is purple, and the individual is red. Wrinkled hermit crab: Likes to climb and change its shell.

1. Purple hermit crab

Purple hermit crabs are a species unique to the Japanese region, and their body color is generally purple-blue, purple, or blue, the joints of the chelicerae and thoracic feet are distinctly yellowish-brown, the dorsal side of the left chela is lined with oblique granules, and the eyes are quadrangular and make a squeaky sound when walking.

2. Concave-footed hermit crab

The most striking feature of the concave-footed hermit crab is the pair of bright red tentacles on the body, their body color is changeable, from dark red to gray-brown or multi-colored, there is a slight curvature at the eye stalk, and the concave-footed hermit crab is relatively shy and often hides in the shallows of the sea.

3. Strawberry hermit crab

Strawberry hermit crabs are mainly found in the Tropic of Capricorn.

In the tropical seas, they are bright red and scattered with white spots, and look very similar to strawberries, this hermit crab can live on land, but it is too long to lay eggs in the ocean.

4. Short-wristed hermit crab

The short-wristed hermit crab is a large species of land hermit crab, their body size is relatively large, the eyes are round, the eye handle is in the shape of a matchstick, and other species of hermit crab are significantly different, and the body color of the short-wristed hermit crab is purple, and some are red.

5. Wrinkled hermit crabs

Wrinkled hermit crabs are the most interactive species of hermit crabs, they will be kept as pets, lively and bold personalities, like to climb and change new shells, and wrinkled hermit crabs are typical nocturnal crabs, generally eating and moving at night.

<> hermit crab, also known as Li Cha's "white house" and "dry house", is mostly produced on the coast of the Yellow Sea and the southern sea. The characteristics of hermit crabs and the characteristics of living in the manuscript are described as follows

Hermit crabs often parasitize shellfish because of their soft body and easy predation by predators, so they can protect themselves. Hermit crabs feed on parasites, algae, food residues, and organic debris. The lifespan of hermit crabs is generally 2-5 years, and they can live for 20-30 years under good feeding conditions.

Both the Hand Crab and the Hermit Crab belong to the phylum Crustaceans, and the main differences between them are the way they live and their ecological roles.

The phase crab is an independent crab that usually inhabits rocky and coral reef areas of the intertidal and shallow seafloors, and is sometimes found in the deep sea. With a short thick body and pincers, they hunt and defend themselves on their own without attachment to other creatures.

Hermit crabs, on the other hand, are parasitic crabs that need to live on the shells or shells of other organisms. Hermit crabs are relatively soft and do not have a hard shell to protect themselves, so they need to seek out and cling to the shells of dead or vacant shells or other shellfish for protection and concealment.

In addition, hermit crabs also use these shells to migrate, and as they grow, they constantly change to larger shells to adapt to their own growth. On the other hand, the crab does not need to be migrated.

Therefore, there is a big difference between the ecological role and lifestyle of the hermit crab and the hermit crab.

Q: What is the difference between a hand crab and a hermit crab? : Xiangshou crabs and hermit crabs are both crabs, but they have some differences:

1.Lifestyle: The phase crab is an independent crab species, while the hermit crab needs to live in the shells of other animals to survive.

2.The shape of the shell: The shell of the sojote crab is usually flatter than the shell of the hermit crab, while the shell of the hermit crab is more rounded.

3.The material of the shell: The shells of the crabs are usually harder than the shells of hermit crabs because they need to protect themselves rather than relying on their shells to protect them.

4.Size: The crab is usually larger than the hermit crab, and the size of the hermit crab usually depends on the size of the shell of the animal it inhabits.

5.Growth: The crab grows by molting, while the hermit crab grows inside the shell and needs to constantly change to a larger shell to adapt to its size.

I'm not quite sure what you're talking about, sorry.

Hermit crab is the general name of the general family of hermit crabs and the general family of land hermit crabs. Its shape is between shrimp and crab, and most of them live in snail shells.

The body is long, divided into cephalothorax and abdomen. Cephalothorax with cephalothorax but does not cover the final thoracic segment. The anterior part of the cephalothorax is narrow, calcified strongly, the posterior part is broadly extended, keratic or completely membranous, and there is a pronounced cervical groove. The abdomen is long, curly or straight, a few are wide and short, and many are asymmetrical.

The general family of hermit crabs includes hermit crabs, quasi-hermit crabs, stone crabs, etc., such as large hermit crabs (square wrist hermit crabs), the body size is very large, the length of the large chela is more than 10 cm, there are many spiny protrusions on the surface and edge of the two chelae, and there are spines on the feet. The general family of terrestrial hermit crabs includes the family of live hermit crabs, terrestrial hermit crabs, chelicerae hermit crabs, etc., such as Ehrlich's live hermit crab and lower tooth fine chelicera. Nearly 1,000 species are known in the world and about 100 species in China.

Most of them are warm water species, and there are a few cold water species in the Yellow Sea.

Except for a few species, hermit crabs generally have asymmetrical bodies and soft abdomen, which can be curled in snail shells. The caudal segment is also often asymmetrical. There are eye scales at the base of the eye stalk.

The first antennal peduncle is often folded, and the second antennal peduncle has multiple spines at the base. The basal ganglia of the third pair of jaws are either adjacent or separated from left to right. A pair of chelicera, with strong chelae, for feeding against the enemy.

The first and second pairs of feet are longer, and the third and fourth pairs of feet for crawling are generally small and have mattresses, which can support the inner wall of the snail shell and stabilize the body. The male genital orifice opens on the basal ganglia of the 4th pair of feet. The female reproductive pores are on the basal ganglia of the 2nd pair of footsteps.

The abdominal limb is degenerate, asymmetrical on both sides, and often exists only on one side. Females are more developed and are used for holding eggs. The left side of the caudal limb and caudal segment is often more developed than the right side, with a rough keratinous mattress.

This specialized tail fan is used to hook the inside of the shell so that it cannot be pulled out. As the body grows larger, it can be swapped out at any time for a larger empty snail shell. Species living in the intertidal zone are often active, while species in the deep sea are sluggish.

Feed on small or dead animals. Terrestrial species are omnivorous. Males are often larger than females.

In order to compete for females, two males often fight each other. Usually crawl on the beach or in shallow water, and in case of danger, it will shrink into the snail shell and plug the snail mouth with chelicera. A small number of species are burrowing or inhabiting in the straight ducts of horned mussels and worms, and the abdomen is not curved.

Hermit crabs often live in symbiosis with other animals, such as sea anemones often have raw sea anemones on the claws of Ehrlich's living hermit crabs, and some hermit crabs live in sponges or coelenterates. The lower tooth chice hermit crab has a series of teeth on the inner edge of the long segment of the chelicera, and the posterior end of the tooth is extraordinarily large, which can rub and make sounds.

Although the hermit crab is also a crustacean, its carapace is not as hard as that of ordinary crabs, especially the abdomen is softer, so it has to burrow the back half of the body into the empty shell to defend itself.

Hermit crabs are not a type of crab and are not a family.

The hermit crab lives in the armor of its predator, but because of this armor, it has to run around on its back, even making its right chelicerae larger than its left chelicerae, or its left chelicerae larger than its right chelicera. It's a bit of a "send people under the fence, everything has to change".

Hermit crabs often live in the shells of dead mollusks to protect their soft bellies, hence the name. There are more than 500 species of hermit crabs in the world, most of which live in the water and a few on land. There are also some hermit crabs that no longer live in the carapace, but have developed a hard shell similar to a crab, also called a hard-shelled hermit crab, and the famous coconut crab belongs to this category.

Kamchatka rock crab (Alaskan king crab) is a close relative of hermit crabs, which were once classified by biologists in the hermit crab family (now in the family of stone crabs).

Common hermit crabs can be divided into three main categories: live hermit crabs, hermit crabs, and terrestrial hermit crabs.

Since hermit crabs are omnivorous and omnivorous, they are known as scavengers by the sea, eating everything from algae and food scraps to parasites, and for home fish lovers, keeping one or two hermit crabs in the aquarium will act as a cleaner.

Hermit crabs generally live for 2 to 5 years, but in good rearing conditions, they can often live up to 20 to 30 years, and the longest recorded survival is 70 years.

Hermit crabs have conch shells, shells, snail shells, and even bottle caps as their homes due to the harsh ecological environment. When the hermit crab is born, the body is relatively soft, easy to eat, and when it grows up, it must find a suitable house for itself, so it attacks the conch and kills and tears the conch. Then get in, hook the top of the snail shell with the tail, support the inner wall of the snail shell with a few short legs, and crawl with long legs outside the shell, holding the mouth of the shell with a large chela.

In this way, it moves into a new home that is environmentally friendly and sturdy.

Hermit crab (arthropod phylum).

Hermit crabs are also known as shrimp monsters, "white houses", "dry houses". It is famous for its fact that it often eats mollusks such as shellfish and takes other people's shells for itself. Hermit crab is mostly found along the coast of the Yellow Sea and the southern seas, and can usually be found in the rocky crevices of the beach and seaside, and sometimes it can be found in bamboo knots, spike coconut shells, corals, sponges, and other places.

As it grows, it will change to a different shell to live in.

Land hermit crabs, also known as land hermit crabs (English scientific name is coenobita commonly known as land hermit crab), as the name suggests, they do not live in the sea, but on land. It is said that the land hermit crab landed on land from the sea about 23 million years ago, and then the abdomen became membranous, and the land hermit crab used the gills to breathe, and some say that they also used the ** in the abdomen to breathe and absorb the oxygen needed from the air. If the gills don't have enough water, they can't breathe.

Therefore, adequate humidity is very important for them, and if the weather is too dry and the humidity is insufficient, it will be difficult for them to survive.

It is a type of crab.

No, because the crab has no shell on it.
