Everyone knows the Brazilian Black tarantula by their hefty, wooly, glossy black bodies and clustered eyes up in front of their faces. They are a beautiful jet-black tarantula in both their bodies and their short, fine hairs.

In certain lighting, it might seem they have some grey or whiter tones to them, but that might just be the gleaming of their dark hairs.


The Brazilian Black Tarantula can be found in and around Brazil, as their name suggests, as well as Northern Uruguay.

They choose to live in the grasslands of these areas, keeping themselves burrowed or hidden from the open. Since they are opportunistic burrowers, they can also be found hiding behind dark wood logs or may find any other abandoned den to call home.

They will also hide beneath rocks, vegetation, and anywhere else that would allow them to hide before ambushing their prey as well as protect them from any predators.


These guys are avid night hunters that use vibrations to find nearby prey.

In the wild, they feed on large insects like crickets, arthropods, mice, lizards, and more.

A mentioned earlier, they will find a place to hide or will creep in their burrow waiting for their prey to come near enough to ambush them. They do not create webs to catch them like other spiders; they will drag them, inject their venom, and eat them alive.


Brazilian Black Tarantulas are relatively slow growers, taking up to 8 years until they reach sexual maturity.

This will be near the end of the male’s life. Females can live up to 20 years and can reach up to 8 inches sometimes when fully grown.


TheBrazilian Blackfemale can lay about 600 eggs, which take a short 2 to 3weeks to hatch.

When tarantulas are ready to breed, the male will deposit his sperm in a small silk sac which he will then store in his pedipalps. Tarantula mating rituals are pretty dangerous and can be life or death for the male.

The male tarantula will first search for a mate and invite her to mate. The male will then attempt to deposit his sperm sac into the female’s pedipalps by holding back her pincers and legs so she cannot attack him.

If he can successfully deposit the sac, he will then have a few minutes to flee after copulation since the female will be entranced with chemicals that come with fertilization.

If the male is not careful or the female thinks he is not a suitable mate, he will become her dinner. If copulation is successful and the female is fertilized, she will then protect the clutch of eggs for their incubation period until they hatch.

Check out this interesting mating process here between two Brazilian Blacks:

If you are going to attempt to breed your spiders, you need to be fast and ready to remove the male after he fertilizes her.


In general, tarantulas are legal to keep in most states, although there may be local laws that restrict captivity, breeding, and such. Check out your local laws to find out what is and is not allowed in your state or city.

You can find them at pet stores easily, but we recommend you also try to look for a rescue group or at least make sure you buy from a licensed, reputable breeder.

The key for this species is getting an enclosure that offers good ventilation since Brazilian Blacks will need a slightly more arid environment.

A good rule of thumb to follow for any tarantula enclosure is making sure that the width of their enclosure is at least three times your spider’s leg span.

You might want to look for a tank of about 12 by 10 inches in size at the very least. The bigger the better and it’s important to note that the width and length of the tank are more important than that the height for these terrestrial spiders.

You might also want to get something that has an escape-proof lid since tarantulas are quite the escape artists.


You should try to keep your spider’s tank clean to reduce the risk of illness. This can be done by taking one day out of your week to clean their tank.

Remove any uneaten food or leftover molt as soon as you see it in their cage.


While they are opportunistic burrowers, they may dig if they are giving the appropriate amount of substrate in their enclosure. The minimum recommendation is definitely 4 inches at the very least.

The best choices for a Brazilian Black are chemical-free potting soil or coco fiber. Again, make sure to give them 4 inches of burrowing space and that you are keeping their environment similar to that of their natural habitat.

Pack down their substrate as tight as you can until it is at the depth you want. This will allow for easy burrowing without anything falling down onto your spider.


Brazilian Black Tarantulas come from a climate that can fluctuate between temperatures of 65 to 85 degrees, meaning they will be most comfortable around these numbers.

They can do just fine around room temperatures but if you find that your home goes below these numbers, you might want to consider getting a heating pad to place under one side of their tank.

This can give your spider a gradient of temperatures in their tank to choose from. Having both a warm side and cool side of the tank can allow your tarantula the choice of regulating their temperatures at the side they want to retreat to.


You should be providing fresh water in a shallow water dish to your tarantula at all times. Not only will this help keep humidity in the tank along with their moist substrate, but it will keep them healthy.

This specific species of tarantula requires 55 to 65 percent humidity ranges to survive.

If you are caring for spiderlings, they may need a light misting to drink from as well as a moister substrate until they have reached an inch in leg span.

These spiders don’t require as much humidity as other tarantula species so misting should not happen after they’ve reached a one-inch leg span. A water dish should be enough to keep their enclosure at the humidity they need.


Don’t worry about lighting but do monitor their tank temperatures since it is more essential to their well-being.

However, while they don’t need lighting, Brazilian Blacks have been seen to bask every once in a while. While it’s not an essential part of their life, if you see your tarantula showing an attraction to light, a 15-watt fluorescent light near their enclosure could still be safe.


These guys can be aggressive eaters and if you let them, they can eat up to seven adult crickets a week!

Spiderlings should be fed one or two smaller insects like pinhead crickets and roach nymphs every other day.

Adults can eat larger insects like crickets as well as various roach species. You can give adults about 3 to 8 insects a month. If you decide to give them less, you can feed them once weekly, as long as you are feeding them less than 8 insects per month.

These tarantulas are great for beginners since they are docile. However, they are also known to be very active spiders.

They will rarely bite and are more likely to show defensive behavior before they even attempt to bite.

If startled or provoked, they have urticating hairs and might react by fleeing first. While they rarely bite, they still have the fangs to do it if you don’t let them be.


Since these docile creatures are rarely aggressive and are fairly tolerant to handling, you might want to try and have a go at it.

If they are acting defensively, give them some time to get used to your presence before you try to put your hand in their enclosure or try to touch them.

Use soft tongs or another light object that won’t crush them to see how they react before you even consider trying to handle them fully.

If they don’t react negatively, you might be able to try to pick them up, but do so at a short height since even just a small fall could injure or even kill them. Make sure you are doing this sitting down on a carpeted floor, just in case they try to flee.
