These good natured spiders require very little space, are quiet, and are easy to care for. They are an ideal species for a beginner. It is a highly underrated pet species. This is probably due to its drab coloration, a subtle mix of browns. However, their hardiness and the large number of offspring they produce per egg sac will no doubt ensure their future in the pet world. For more Information on keeping Lizards see: |

Distribution: The Oklahoma Brown Tarantula or Texas Brown Tarantula is found in Oklahoma and northern Texas in the United States.
Description: The Oklahoma Brown Tarantula is a medium-sized stocky spider. They have about a 4 - 5" (10 - 12.5 cm) leg span that is covered fine hairs in shades of brown. Females and immature males have a light brown to tan carapace, a coffee brown abdomen, and darker brown legs. The mature male molts and the stocky body type is replaced by a long-legged spindly spider with tan carapace, brown abdomen, and long black fuzzy legs. He will also have tibial hooks which he uses for breeding. These can be clearly seen on an adult male Oklahoma Brown. The females are stocky.
These spiders reach maturity around 8 to 10 years of age. The female can live up for up to 36 years while males live 7 - 12 years.
Care and Feeding: The Oklahoma Brown Tarantula feeds on a variety of insect prey including crickets, grasshoppers and locust, and even mealworms.
Environment: Oklahoma Brown Tarantulas live in shallow burrows under flat stones in nature. This tarantula will thrive in a simple "Southwestern Prairie" type of enclosure. A 3" deep substrate of a mixture of sand and peat moss can be used as the base for the enclosure. On top of this layer, a shelter made from bark, cork bark, or a supported stone shelter should be added. This will provide a somewhat moist and secure hiding spot. The spider will use this area for shelter during the day and especially during molting time when the extra humidity becomes important.
Temperature and Humidity requirements: The enclosure can be maintain between 50 ° to 80 ° F with a humidity level of 50 to 60%.
Social Behavior/Activities: The Oklahoma Brown Tarantula is one of the most docile species available in captive collections. They will rear up when agitated and will even occasionally bare their fangs. After a short display, they will beat a hasty retreat or more commonly will simply walk away.
Handling: Carefully pick up these tarantulas by cupping them gently with the legs folded under their bodies. Another gentler method is to simply place a hand out flat in front of them and gently prod the tarantula's abdomen, forcing it to walk onto the hand. As they walk, simply place the other hand in front and have the spider walk across your hands.
They do not like to be blown upon and will jump, scurry away, and may even flick urticating hairs or bite if disturbed too much. All in all, these guys are very tame and make wonderful pets.
Breeding/Reproduction: The adult male Oklahoma Brown Tarantula goes through a rather dramatic sexually dimorphic change on their final or penultimate molt. They change from a stocky brown spider to a slender spider with long spindly legs and an overall black coloration. They also have tibial hooks and swollen tips to their pedipalps, used for breeding.
The Oklahoma Brown can be bred in captivity if certain pre-mating conditions are maintained. The females seem to benefit from a cooling period of a couple of months prior to mating. Once a mature male is produced, and he makes a sperm web, he should be introduced into the female's enclosure.
He will approach the female's shelter cautiously, tapping and vibrating his legs. The female will be "lured" out of her burrow or shelter and the male will typically lunge forward to use his hooks to hold the female's chelicerae and to push her into an almost upright position to give himself access to the female's epigyne for mating. The male will insert either the left pedipalp, right pedipalp, or both alternately into the female's epigyne and inject the fertilizing fluid into this area.
If fertilized, the female will produce an egg sac in the following weeks. This species produces large egg sacs, usually containing in excess of 250 babies. A mature male can be introduced to multiple females or can be reintroduced to a female to enhance the possibilities of a successful pairing. Typically, the male will die in the weeks following a successful mating.
Ailments: Tarantulas are generally quite hardy and adaptable if they are provided with the right environment. A few signs that may indicate that your pet is not acting or feeling normal are a loss of appetite, lethargy, looking overly skinny, or pacing the enclosure.
(A tarantula on its back is probably NOT sick. Most tarantula species flip onto their backs during molting. Though this is a very stressful and delicate time for tarantulas, if the humidity and warmth levels are correct, they will molt their exoskeleton, roll over, harden up, and within a week or two be ready for their next meals.)
Availability: Oklahoma Brown Tarantulas or Texas Brown Tarantulas are sometimes available from dealers / breeders who have found a wild-caught female with an egg sac in the later stages of development. This only occurs sporadically in the trade.
Oklahoma Browns and many of the terrestrial species from North and Central America have confused tarantula breeders. Often a pair will mate but the female will never lay eggs. Occasionally a female will lay eggs, fold up her egg sac, and either eat it or abandon it after a few days. We are experimenting with conditioning females by cooling them in a wine cooling rack. We believe that perhaps these females need some "triggers" to breed and produce spiderlings successfully.

| I just convinced my arachniphobic mother to let me catch an Oklahoma Brown and keep him. I named him Puck after the Character in A Midsummer Night's Dream. The second day I was able to pick him up and let him crawl on me. I noticed he wasn't eating much, he's going to molt as I found out. Anyways these are great tarantulas, and I love my Puck lol. :)

| My friend Anthony caught a male Tx Brown in Amarillo at a job sight and brought it to me, cause I've always had snakes, spiders and scorpions as pets. Even being caught in the wild it is very docile. Watching it catch crickets is really amazing, I've never seen a spider or scorpion go after its prey with such fury!

| I just saw an enormous spider whilst walking my dog (Austin, TX). My husband didnt believe it was a spider and so I took him out to see if it was still there. It was. Whilst I was climbing up the walls, my husband was studying this rather beautiful creature. He has lived in Texas for 30 years and has never seen one. I am from England and in five years have never seen one. We came back inside and googled. We believe it is a Texas Brown Tarantula. I guess I should be delighted for the experience.

| My husband and I were on a walk this evening and saw one of these tarantulas crossing the road in the subdivision we live in. It was quite interesting. We live in Little Rock, Arkansas.

| We seem to have the perfect breeding grounds, or habitat for them. We usually encounter 5 or more each summer at our home. It doesn't help that both my husband and I are terrified of spiders.
