Appearance: How to Identify Cobalt Blue Tarantulas

Cobalt blue tarantulas are medium-sized tarantulas famous for their iridescent blue legs and light gray bodies with dark gray chevron patterns. Its leg span is around five inches long and females are slightly larger than males. These spiders look dark from a distance, but the bright blue become apparent the closer you get.

Some studies suggest that tarantulas can see specific colors and that their vibrant coloration is used to attract mates, communicate with others, and conceal them from danger.

Males and females appear similar, but they exhibit sexual dimorphism during the final molting process. After a male’s ultimate molt, its coloration turns bronze, and it develops mating hooks. Females also become larger than males during the final molting and live longer.

Temperament

The cobalt blue tarantula is very popular in the pet trade despite its propensity to bolt and become defensive. These nervous creatures do not like to be held and don’t do well during rehousing or habitat maintenance. Compared to other tarantulas, cobalt blues are unpredictable and readily bite when frightened. Even baby tarantulas are known to inflict a painful bite when handled.

Cobalt blue tarantulas are also fast and contain potent venom. While they don’t produce enough to kill a human, their bites produce a stinging pain, muscle cramps, and inflammation. Some people may develop a more serious allergic response to a tarantula bite.

Habitat: Where to Find Cobalt Blue Tarantulas

In the wild, these tarantulas live in the tropical rainforests of Southeast Asia. You can find them in several countries, including Thailand, Burma, Laos, Cambodia, Vietnam, and Myanmar. This species faces pressure in its wild habitat due to deforestation and capturing for the pet trade.

They are fossorial species, meaning they dig their own burrows and live underground. Even in captivity, the cobalt blue tarantula spends much of its time inside a burrow and only leaves to find food.

This species needs high humidity and warm temperatures between 77 and 85 degrees Fahrenheit. Pet tarantulas need lots of moist substrate for burrowing and a large tank. The larger the tank, the less likely they are to bolt up and out the enclosure.

Diet: What Do Cobalt Blue Tarantulas Eat?

If you have a pet cobalt blue, you may notice they only come out of their burrows when its feeding time. These tarantulas have voracious appetites due to their quick growing phases.

They like to stay near the edge of their burrow, waiting for prey to cross their path. Once they snatch their food, they return it to the den before eating at their leisure.

Appropriate food for a cobalt blue tarantula is crickets, mealworms, baby mice, and cockroaches. Before feeding your pet anything from outside, please think twice, as they can contain parasites and pesticides.

It would be best not to feed your cobalt blue during the molting process to prevent damage.

In the wild, cobalt blue tarantulas will consume anything small enough that comes near their dwelling.
