Coconut crab is a unique hermit crab, which grows on many coral islands in tropical Pacific Ocean and Indian Ocean. Hermit crabs generally live in the snail shells that move with their stomachs, so their bodies are soft and asymmetrical, but coconut crabs get rid of the snail shells that restrict their growth and "develop freely". It can find or dig caves in places such as sand or tree roots. Afraid of strong light, I squat in the cave to rest during the day and go sightseeing and foraging at night. A coconut crab lives alone in a cave. When he grows up, he will dig a bigger cave to adapt to it.
Question 2: Does anyone know how to raise coconut crabs? Go to the shrimp and crab channel in the aquaculture section of the agricultural network, and see the user information in the upper left corner of my user information page.
Question 3: Can coconut crabs keep any animals by themselves, as long as you want to keep them and know them well enough? Everything is fine. This animal is not much smaller. I have never seen China's smallest individual length smaller than a pulsating bottle. It is said that Tokyo larval coconut crabs can be mixed with hermit crabs of average size into the pet market, but this animal grows very slowly and takes 20 years to grow up. Might as well buy an adult. But I still want to remind this guy that this thing is a wild animal, extremely powerful and destructive beyond your imagination. If you really want to raise it, the largest sorting box+a cushion of more than 20 centimeters, it is best to use coconut soil or that kind of soil that is easy to harden+thick trunk as its habitat +2 overweight pots, one fresh water and one seawater. Adjust the seawater by yourself, about 0.2-0.5%+ food apples, mangoes, coconuts, crabs, leafy vegetables, fish, etc. Also; Clean the environment once a day, dig out the soil bit by bit and find out the food residue. At the initial stage of feeding, drip water into his cheek with a syringe to make him breathe smoothly. Before he can find water by himself, he must lock the feeding box, otherwise he may scrap the box first and then run away. Hermit crabs are all animals with extremely high IQ, and they may escape somewhere. Remember, the temperature is above 28 degrees, the humidity is above 75%, and it is highly ventilated.
Perfect the explanation of sorting box. The sorting box here does not refer to the common sorting boxes in supermarkets. That kind of box can only be a little bigger than a coconut crab. It's a little difficult for adults to turn around. And after a long time, this box will become brittle and easily destroyed. More recommended is the PE aquatic product box, which is very large and can reach several white or even thousands of liters. And strong and not easy to be destroyed. Many lovers who keep snapping turtles or giant fierce fish like to use this kind of box, and the price is relatively high. But it's worth it, but it only meets the basic needs of coconut crabs, if we can build big boxes or keep them in the house. It couldn't be better.
Question 4: The population status of coconut crabs. Coconut crabs are famous for their fresh and tender meat. However, due to the crazy killing and destruction of its natural habitat, it is increasingly difficult to find traces of coconut crabs in their habitats and become endangered animals facing extinction. This situation has attracted people's attention, and many countries have formulated relevant measures to strictly protect it, and are studying the methods of artificially breeding coconut crabs. Coconut crabs, a specialty of Sulawesi, Indonesia, are famous all over the world for their tender meat, but now the number is greatly reduced. Young coconut crabs are often targeted by other animals such as monitor lizards, wild boar and big birds. However, the real threat of coconut crabs comes from human beings.
Question 5: What is the easiest thing for blue crabs to gain weight? I don't know if this will help you. r(s_t)q？
Underwater world
Marine animals sleep in various postures.
Fish sleep for a short time, some for a few minutes, some for only a few seconds. For some fish, people fall asleep in the blink of an eye.
Marine mammals sleep differently from fish. For example, when a dolphin sleeps, it floats underwater 1 ft at night and falls asleep peacefully, while its tail still swings every 30 seconds.
When a seal sleeps underwater, it wakes up with every breath. In other words, they need time to sleep between breaths.
Sea otters, which are produced along the coast of the North Pacific Ocean, will form an oval bed with seaweed at the seaside. When they sleep, they hide their bodies in the middle and their stomachs face the sky. If it is content to sleep somewhere, it will sleep there every day.
Walruses growing in the Arctic Ocean sleep in different ways. It doesn't sleep on its back, but vertically in the water, with its head above the water.
A lovely beaver usually sleeps during the day, leans his head back and sometimes grinds his teeth. Especially the little beaver, sleeping is the most interesting. They sleep side by side, and some even put their feet under their heads, which makes people laugh.
Special functions of fish
Fish's eyes
Fish's eyes are typical myopia, and there is another eye line. The lateral line of a fish grows on the scales on its side, called lateral line scales, with one on each side. There is a small hole in the lateral line scales, which transmits external information to the brain through the sensory organs connected with it, so that the fish can see everything outside.
Fish erduo
People always think that fish have no ears. In fact, the fish's ears are not in vitro, but in the skull, which is composed of small pieces of calcareous otoliths, lymph and sensory cells. External sound causes lymphatic vibration, otoliths and sensory cells pass through the nervous system to the brain, and fish hear this sound. Fish's ears also have the function of maintaining body balance. When the body is unbalanced, lymph and otolith will press the sensory cells and report to the brain immediately, so that the fish can keep balance in time.
Fish's nose
Fish's nose is an important organ for locating and foraging. When water enters the nasal sac from the front nostril and then flows out from the back nostril, the olfactory cells in the nasal sac will send the captured information to the central nervous system for storage. Most fish rely on their noses to sense and analyze the smell of water, thus completing nesting and homing. Experiments show that many fish can swim back to their original nests from several kilometers or even dozens of kilometers by relying on their sensitive noses.
Interesting crab
Crabs are mostly wild, so they are called "wild media" and are unique among animal groups. The crab has five pairs of chest feet on both sides of its head and chest. Except for the first pair of pricking feet, the other four pairs are all walking feet. Because the joints of our feet can only move left and right, we have to push sideways with one foot and run wild with the other foot on the ground. In addition, because the feet on the same side are long in front and short in the back, they can only turn around when encountering obstacles, and often climb in one direction along obstacles.
Intertidal zone and coastal beach are the main habitats of crabs, and there are usually dozens of species. In China's coastal beaches, there are mainly Eriocheir sinensis, Eriocheir sinensis and fiddler crab. They all like to hide under rocks or dig holes in mud beaches. Their caves are all over the beach, and there are 2 ~ 3 caves in one square meter. Caves vary in depth, but generally there are two caves in each cave. Crabs hibernate in the depths of caves in winter until spring warms the earth, and they climb out of caves again to prepare for breeding. Crabs move quickly, and the peak of daily activities is just after dark at dusk. At this time, almost all individuals gushed out of the cave, all over the roads and rivers, which were dense and spectacular from a distance. Their exoskeletons are thin and their eyes are big. They always look around warily to avoid their prey as soon as possible. There is a Chinese mitten-handed crab that lives above the open sandy coast. Its stinging feet are asymmetrical left and right, and the stinging palms are finely carved, which is called the sound ridge. Once in danger, they will all enter the cave at a very fast speed of 1- 1.6 m/s and disappear without a trace. There is also a small sand crab. When frightened, it will.
