Mexican Giant Red Knee Tarantula (scientific name: Brachypelmaannitha) is native to the dry deserts in southwest Mexico and is a controversial species within the Brachypelma genus. It is divided into two distinct groups among scholars and enthusiasts, who either support or do not support their existence as a separate valid species. It is said that DNA testing was carried out in 2005 and it was finally determined to be a valid and independent species.
Latin name: Brachypelmaannitha
English name: Mexicogiantredknee
Chinese name: Mexican Giant Red Knee Head/Mexican Giant Red Knee Bird-Eating Spider/Mexican Giant Black Orange Stripe
Chinese name: Mexican Giant Red Knee Head, foreign name: Brachypelmaannitha, origin: Southwest Mexico
Tropical grassland climate, average annual temperature 25-27°C, English name: Mexicogiantredknee
Mexican Giant Red Knee Tarantula and Mexican Red Knee Tarantula are both spiders of the genus Brachypelma, and their names are similar. However, literally speaking, the adult Mexican Giant Red Knee Tarantula has longer leg span than the latter. The body size is larger.
Secondly, the feet and tarsi of Mexican Red Knee Tarantula are black and orange, while the second to last joint to the last joint of Giant Red Knee Tarantula is a relatively coherent orange-red color, which makes it easier to distinguish in terms of color.
They are clearly divided into two factions among scholars and enthusiasts, supporting or not supporting their existence as a separate valid species. It is said that DNA testing was conducted in 2005 and it was finally determined that they are a valid independent species.
Their habitat is only a very small area, which overlaps with the habitat of Mexican Red Knee Tarantula. Therefore, those who oppose the view that they are a separate species basically consider them as regional variants or subspecies of Mexican Red Knee Tarantula.
In addition, their chelicera
The Mexican Giant Red Knee Tarantula is recommended for the spider enthusiast group of climbing pets and bird catches. The first segment of its legs and antennae that extend from the body are covered in black fur, while the remaining segments are orange-red. The black part on the dorsal shield is surrounded by an orange section in a triangular shape, and the abdomen is covered in short, dense black fur, with long and sparse orange-red hairs on the sides.
Intestinal inflammation
Contrary to wasting disease, this is when the spider eats too much. The owner constantly feeds the spider, or the food temperature is too low during feeding, which can cause bloating and abdominal pain in the spider, eventually leading to intestinal inflammation.
Hemiplegia
Spiders do not require a high environmental temperature, but when the temperature is too high, especially in summer, with high temperature and humidity, if the spider's cage is too far away from the ventilation opening, the spider may experience heatstroke-like symptoms and have paralysis in its legs, resulting in hemiplegia.
Black rot disease
Not eating or moving, decreased alertness, and the appearance of black, ulcerative lesions on the abdomen are signs of spider black rot disease. The reason for this condition is that the water and food are not fresh, and if the spider eats food with pathogenic bacteria, it will be infected with black rot disease, which can be fatal.
Mold disease
Especially in the southern regions, the hot and humid weather in summer makes it easy for the spider's body surface to be invaded by bacteria. The spider's joints become increasingly stiff, and its body becomes increasingly damp, creating an environment where bacteria can thrive and cause mold spots on the spider's body.
Slightly moist peat soil or coconut soil, well-ventilated enclosed environment, small water bowl, hiding space, etc.
The spider itself does not need direct sunlight. Young individuals can be fed with mealworms and cherry red cockroaches. Large individuals can be fed with large mealworms, Dubia cockroaches (adults), mice, small lizards, etc.
