This type of spider is widespread in South America - Chile, Argentina, Bolivia. Prefers to dwell on arid soils, but with the possibility of digging long and deep holes.
Very common for captivity.
It is forbidden to catch them from nature; they are included in the second CITES application.
Body length 5–7 cm, paw span up to 15–16 cm, sexual dimorphism is pronounced, females are larger than males.
Body color black with red thick hairs, looks very elegant. There are two color options - regular and red, with even more red hairs.
The hairs on the body are thick.
Like all spiders, feeding the gram table is often not worth it. Young spiders can be fed once every 1 to 2 days to speed up the growth rate, but they can endure a week-long hunger strike without consequences.
Adult spiders need to feed once every 1 - 2 weeks, you need to feed insects of the appropriate size - no more than the spider itself. This can be cockroaches, crickets, locusts, bestiality, flour worms.
Adult spiders can withstand a monthly hunger strike, and even a longer hunger strike without harm to health.
Before molting, during it and for some time after feeding the spider should not be.
For successful breeding of this species, a gram bench may need wintering - after mating, you need to lower the humidity and temperature.
Spiders of different sexes are kept separately and, well-fed, the male is planted on the female. It is necessary to carefully monitor the behavior of the female, as they can be aggressive towards the male and can even eat him, although this type of gramophone rarely does this. If the female is threatened, the male should be seated. For breeding, it is better to take a female at least 4 years old, otherwise she may not weave a cocoon.
After 3 months of the mating ambassador, the female builds (weaves) a cocoon and cobwebs, inside there are eggs. A cocoon can contain from 100 to 300 eggs, which hatch in two spiders in two months.
Gram-tables grow for a long time, reach puberty late, females in 3 - 5 years, males in 2 - 3 years.
Spiders are kept in terrariums called spiders. They are usually cubic in shape; for a gram table, a horizontal terrarium is needed. They contain them strictly one by one, in spiderwebs measuring 30 by 30 by 30 cm. Coconut substrate or coconut shavings should be laid on the bottom with a layer of at least 5 cm, since this type of spider usually digs holes. You can put shelter - bark or coconut or an inverted flower pot, but not all spiders use this. This is a terrestrial view and they do not climb well on the glass, so it is recommended that a horizontal terrarium is recommended.
The spider web should have a tank with fresh water.
Temperature 24 - 26 degrees.
Humidity 40 - 60%, the soil must be sprayed.
Life span 3 to 4 years for males and over 20 years for females.
This is a large, beautiful view of the spider, recommended for beginners.
Thick irritating hairs grow on the body of this type of gram-tables, under stress, the spider combes them, when they get on the skin or mucous membranes they cause severe itching, but combing is rare and only in extreme cases.
The poison of the gram table is weak and not dangerous for humans if there is no allergy to it.
Chilean pink tarantula, or Chilean pink tarantula (lat.Grammostola rosea) - one of the most beautiful representatives of the Spider-Bird family (lat. Theraphosidae). Attractive coloring, impressive size, unpretentiousness and benevolent character made him a popular and desired inhabitant of home terrariums.
The bite of a cute spider is painful, but completely harmless to humans. Painful sensations usually disappear within a few hours without consequences for the health of the victim.
The first scientific description of the species was made in 1837 by the French zoologist Scharl Valkener.
Habitat and habitat
Chilean pink tarantula is common in Chile, Argentina and Bolivia. It settles mainly in humid regions in areas with loose soil. Individual populations have adapted to exist in the Atacama Desert, which is considered the driest on our planet.
The spider Grammostola rosea leads a terrestrial nocturnal lifestyle. Its habitat is characterized by large temperature differences during the day and depending on the time of year.
In summer, he hides in the surface layer of the earth, tearing holes to 1 m in depth, and in winter falls into hibernation. It occurs already at an ambient temperature below 10 ° C. A thermophilic creature buries itself in the ground and patiently awaits warming.
He tries to stay away from his relatives, since a lack of food supply often leads to cannibalism.
The pink tarantula feeds mainly on insects living on the surface of the soil. He sits for a long time at the entrance to his shelter and waits for the food passing by. Cockroaches and crickets most often become its prey, and with a successful combination of circumstances scorpions and small mammals.
He grabs the victim with his two powerful pedipals and kills by injecting a small amount of poison during a bite. The excretory channel of the poisonous glands is located in the chelicerae. Sometimes a spider considers it unnecessary to spend poison and simply destroys the victim’s body with its jaws.
The hunting trophy is first softened in the oral cavity under the influence of enzymes, and only then appears in the stomach located in front of the body. There is its final digestion. Satiated, a hunter can sometimes stay in a blissful state of happiness and peace for months. Only pretty hungry, he again goes hunting.
One animal out of six crickets is enough for two weeks.
To protect against predators, burning serrated hairs are used, which, in case of danger, easily come off with their hind legs from the abdomen (abdomen) and end up in the airways or mucous membrane of the offender, causing severe itching and an allergic reaction.
Such a means of self-defense is most often used by young tarantulas, therefore, when communicating with them, increased caution is required.
The mating season begins in early spring after the end of hibernation, when the soil warms up to 13-15 ° C. Males go in search of females, fully relying on their sense of smell. The meeting takes place thanks to the pheromones secreted by the female.
3-6 weeks after mating, the female lays 100-200 eggs in her shelter and envelops them with a cobweb in the form of a cocoon. Sometimes in the cocoon at the record holder there are up to 500 eggs. The offspring is born 8-10 days after masonry.
Inside the cocoon, nymphs go through several stages of development and molt twice. Around the tenth week, small spiders form. They spend several days with their mother, and then scatter around the neighborhood. They are driven by a survival instinct.
During the nourishment period, a hungry mother can enjoy her offspring, forgetting her parental duty.
Young spiders feed on small insects. At this time, they are very vulnerable and are often attacked by larger predators. The main danger for them is scolopendra, ants and wasps.
They become sexually mature quite late, at the age of at least 6-8 years.
The maintenance at home of the Chilean pink tarantula does not present special difficulties even for beginners. For one adult, it is enough to have a terrarium measuring 40 x 30 x 30. A lower height is also allowed.
It is advisable to put a thick layer of soil at the bottom so that the spider can make a refuge in it. The soil must be constantly moistened and loosened. Instead of soil, you can use a bed of peat moss or humus with a thickness of about 7 cm.
As food, you can give crickets, cockroaches, flour worms and other small invertebrate animals.
The optimum temperature is from 25 ° C to 30 ° C, and humidity is more than 60%.
Terrarium should not be located in direct sunlight and drafts. There should be no sources of household noise near it. From the inside it can be decorated, but for spiders it does not matter. Decor elements should not have sharp edges and not be high. Falling from a height is dangerous for furry pets.
Juveniles are also kept in ordinary plastic containers, in which vents are drilled.
Body length is 5-7 cm. Color varies from reddish to dark brown. The cephalothorax is protected from the back by chitinous carapace. In adult males, it acquires a pink color.
The hairline is short. Two light lines pass along the legs, especially clearly visible in dark specimens.
In young individuals, the legs are light pink. With each molt, they become darker. The back is dark brown. Chelicera and abdomen are covered with burning hairs.
Female representatives live on average about 12 years, some live up to 30 years. The life expectancy of males rarely exceeds 6-8 years. Most of them die soon after mating.
