Discover All The Facts About Cobalt Blue Tarantula

Cobalt Blue Tarantula: The World’s Rarest Species

The cobalt blue tarantula is a very rare creature. As its name suggests, it has an amazing metallic blue shade and aspect. The cobalt blue tarantula was formerly known as Haplopelma lividum. It is a member of the Theraphosidae family of spiders. Of the 800 (roughly) species of tarantulas that exist worldwide, this is one of the rarest and most elegant. The tropical Southeast Asian jungles of Vietnam, Thailand, Myanmar, Malaysia, Cambodia, Laos, and Singapore are home to this species of tarantula. Furthermore, similar to all other organisms on our planet, Haplopelma lividum possesses unique traits that set it apart from other living forms.

Facts About Cobalt Blue Tarantula

Here are a few amazing facts regarding Haplopelma lividum:

Appearance Of The Specie

Even though this species initially seems to be brown or black, under the proper lighting conditions or upon closer examination, its real color is strikingly visible. The mouthparts behind the fangs are brilliant red, the cephalothorax is gray or greenish-blue, and the legs have a metallic iridescent blue color. Additionally, hair that resembles a yellowish fuzz covers the abdomen and carapace. However, there are subtle variations amongst cobalt blue tarantulas. Many have bright white stripes on their belly, while some have black upper legs and a neon yellow ring around the carapace. 

Some may even have vivid yellow highlights surrounded by white splashes on their leg joints. Additional variants include brown and tan hues on the belly and cephalothorax. Up to the males’ last molt, the female and male tarantulas have the same appearance. Moreover, this species’ young spiders are pale blue.

Size Of Haplopelma lividum

Although they typically develop to a length of 13–14 cm, or 5–6 inches, mature spiders can reach up to 9 inches in the wild. Males are half the length of females, which range from 5.3 to 8.5 cm (2.0 to 3.3 inches) in length. However, young spiderlings are only one centimeter long. Meanwhile, they develop quickly; in just the first year, they reach a height of 1 inch or 2.54 cm. Males mature quickly and frequently reach adulthood in the first year of life.

Molting And Lifespan

Molting is the process by which tarantulas alter and repair their exoskeleton and replace any lost limbs. The cobalt blue tarantula molts once or twice a year, just like the majority of other tarantula species. However, the molting process uses up a lot of energy, which makes it highly stressful. Therefore, the tarantulas require many days to fully recuperate from their molt.

Moreover, in comparison to male tarantulas, females live far longer. The average longevity of a boy is 5–6 years, but the average female lifespan is 15–18 years. Female tarantulas can live up to 30 years in the wild.

Personality Of The Species

The personalities of this type of tarantula are fierce, protective, and combative. Even the youngest spiderlings fight with great ferocity and adopt aggressive postures. Because they are extremely sensitive and wary, they instantly assume a scary posture when they are approached. Thus, the pet owner finds the rehoming procedure extremely challenging due to their violent and short-fused conduct. This species has a great ability to flee. It uses its powerful fangs to exclusively bite to attack and protect itself.

Nature And Residential Areas

In the wild, tarantulas live in subterranean tunnels. They construct their dens on their own sometimes, or they may reside in ones that other animals have already found. Furthermore, it is a nocturnal species. Thus, they spend the daytime hours in the burrows and venture out at night.

Venom And Prey

Even though this species bites quite painfully, people are not thought to be at risk from its venom. They only venomously affect their victims with such vigor and quantity. The cobalt blue tarantula can survive for extended periods without a meal. In addition, the tarantula, like other spider species, kills to get food. Other spiders, mice, insects, and amphibians are its primary prey. However, after injecting the victim with a venom that renders it motionless, it takes the victim to its burrow to eat it.

Senses And Reproduction

Despite having eight eyes, tarantulas have poor vision. This species mostly depends on its body’s sense receptors because it has weak vision. Furthermore, its legs and body hair have the most sophisticated and reliable sensors.

The blue cobalt tarantula eventually reaches the maturity stage necessary for reproduction in the third year. After eight weeks of mating, the female creates a silk cocoon. It deposits her eggs on something that resembles a sac that resides within her home. However, with each mating, it may yield 100–1000 eggs. Many people who love spiders maintain and cherish this small, feisty creature despite its hostile and aggressive character.
