Feeding method of newt
1. Newt belongs to a larger pet, and a large glass fish tank should be prepared for it. Let the salamander have enough activity space, and it is also convenient for the family to watch.
2. Create a good ecological environment for the newt. First, lay a layer of clean sand and gravel on the bottom of the fish tank and inject well water with a depth of 30 cm. Then put a small amount of Ceratophyllum or aquatic plants, the gravel can absorb the feces and dirt removed by the salamander, and the aquatic plants can carry out photosynthesis to improve the dissolved oxygen in the water.
3. The water quality for raising salamanders is preferably clean pool water. Of course, you can also choose well water or tap water, but well water and tap water need to be exposed to the sun for 3-5 days to remove the chlorine contained in the water in order to raise salamanders.
4. The water quality of salamanders needs to be changed regularly, once every 15 days in winter and once every 3-5 days in spring, summer and autumn.
Newts like to eat live animals. Earthworms, tadpoles, dragonflies and Daphnia are all its favorite foods. Of course, you can also buy frozen shrimp in the supermarket, thaw it and cut it into small pieces to feed the salamander.
Methods of nursing and raising salamanders
1. Take care of salamanders in glass fish tanks or feeding tanks. Glass fish tanks or feeding tanks are most suitable for raising salamanders. Choose a water tank with a capacity of about 37 liters, so that your salamander will have enough space for a series of activities such as hiding, digging and sleeping. Glass fish tanks are most suitable for raising aquatic or semi-aquatic salamanders. Remember to clean the water tank before building a shelter for your salamander. If you don't want to buy a glass cylinder, you can also use a plastic cylinder or an organic glass cylinder instead.
2. Cover the water tank tightly. Newt is an excellent climber? They can quickly climb to the edge of the water tank with a capacity of about 37 liters. It is for this reason that it is particularly important to match a tight cover in order to prevent the salamander from escaping. The veil is the best because it helps to circulate air. If you can't buy a screen cover, a protective cover will do.
3. Determine whether your newt needs an aquatic, semi-aquatic or terrestrial shelter. It depends on the type of salamander you have or want to buy. If you really don't know your salamander's life preferences, you can consult a pet store or search for relevant information online. Aquatic salamanders, such as salamanders, live in the water environment all the year round.
Semi-aquatic salamanders need to be cared for in tanks with half water environment and half land environment.
Terrestrial salamanders don't have to have water to live in.
4. Improve the equipment of feeding tanks. It also depends on your newt type. Remember, the steps listed below are just general guidelines? The specific details can be freely played according to personal preferences.
Aquatic feeding tank: Choose a glass fish tank to take care of your salamander. Lay about 5 cm thick washed gravel on the bottom of the water tank. Tilt the water tank slightly to make the accumulated rubble form a transition slope of 5 cm to 7 cm. Carefully plant some water plants at the bottom. Because salamanders are easy to destroy aquatic plants, they should be replaced frequently.
Semi-aquatic feeding box: the feeding box is divided into two parts with half plexiglass to create a living environment with half water and half land for salamanders. Spread gravel about 5 cm thick on the bottom of the pool in the water area and plant some aquatic plants. It also makes the gravel form a small slope, which is convenient for the salamander to crawl freely from the water to the land. Gravel with a thickness of 5 cm is also laid on the bottom of the cylinder in the land part to cover the substrate (that is, planting ground cover plants). The substrate should be similar to the soil cover of broken bark or coconut fiber. Cover with a layer of sterile potted soil or pastoral soil.
Land feeding box: the feeding box is designed as the land part of semi-aquatic feeding box, but covers the whole feeding box. A variety of plants or mosses.
5. Provide a small bowl of water for terrestrial salamanders. Because terrestrial salamanders are not used to water, they only need to prepare a relatively small shallow bowl, otherwise some salamanders will easily drown.
6. Set some hidden places in the feeding trough. No matter what kind of salamanders you keep, it is necessary to set up a good hiding place for them. Newts often feel tired, so it would be great to build some resting places for them. Like caves, large pieces of ceramic fragments, large pieces of bark and store-bought? Hiding place? Are all good choices.
Related characteristics of salamanders
Newts are shy animals. They usually hide in wet places or underwater. Their skin is smooth and sticky, their tails are long and their heads are round. Many of them live in water all their lives, while others live completely on land, and some even live completely in wet and dark caves. Most salamanders, whether living on land or in water, have to breed in water.
A series of larval development processes experienced by salamanders are called metamorphosis. Terrestrial salamanders lay eggs on land, and the development of larvae occurs in eggs. When cubs hatch, they look like miniature versions of adult animals. Aquatic salamanders lay eggs in water and hatch into tadpole-like larvae. Eventually, they lost their gills. Some salamanders don't lay eggs, but can give birth to fully formed cubs.
Regenerative ability
One is called? Macrophage? Our immune cells are vital to the regenerative ability of salamanders, which can help scientists control this process and even apply it to humans. If macrophages are removed by the system, salamanders will lose the ability of limb regeneration and form scar tissue.
It was once thought that macrophages were not conducive to the regeneration process. This study shows that this is not the case. If macrophages do not participate in the early stage of healing, regeneration will not occur. It is necessary to study how macrophages promote the regeneration process.
The tissue regeneration process of salamanders will not produce scars, but will copy the damaged parts almost perfectly. Newt is regarded as a template for perfect regeneration. Besides the ability to heal injured spinal cord and brain injury, like this? Holy Grail? In addition to its application, studying the healing process of salamanders will also help to develop a series of new therapies for treating a large number of common diseases, such as heart disease and liver disease, which are all related to fibrosis or scar.
The research of scar-free cure can greatly accelerate the postoperative recovery process of patients. Studies have shown that many animals have the ability to regenerate, but most animals have turned off this ability during evolution.
gene
The genome of the salamander is very large, ten times larger than the human genome.
There are more than 120000 RNA transcripts in the salamander transcription group, and about 15000 transcripts encode protein, among which 826 transcripts are unique to salamanders. In addition, some sequences are differentially expressed between original tissues and regenerated tissues.
protect
Newts can crawl very slowly on their short four feet, whether on the surface, trees or underground. Surprisingly, they can walk on the mud surface at the bottom of the pond with their front feet or toes, and speed up their walking by swinging their tails.
Most salamanders are brightly colored and beautiful, but they are poisonous. They use this bright and dazzling color to warn intruders, so that those predators who are eager to move will stay away. When the snake attacks the salamander, the salamander's tail secretes a glue-like substance, and they beat the snake's head mercilessly with their tails until Shekou is stuck by the secretion. Sometimes there will be a scene where a long snake is stuck together by salamander mucus and can't move.
