Aphonopelma anax commonly known as the Texas tan tarantula is a species of spider belonging to the family Theraphosidae. The spider is very desirable as a pet due to its docile nature. Like most Aphonopelma species it has a very slow growth rate. The Texas Tan is one of the largest tarantulas found in the United States as it commonly reaches a leg span of 5 inches at full maturity and sometimes reaches 6 inches. It is similar in coloration to Aphonopelma hentzi but considerably darker.
