. "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."@en . . . . . . . . . . "Aphonopelma anax"@en . .
