Texas brown tarantula

Aphonopelma hentzi, the Texas Brown tarantula, (also known as Oklahoma Brown tarantula or Missouri tarantula), is one of the most common species of tarantula thriving in the southern-most United States today. Texas Browns can grow in excess of a four inch leg span, and weigh more than 3 ounces as adults. The body is dark brown in color. Shades may vary between individual tarantulas and is more distinct after moult.
Life Cycle
Female A. hentzi can lay up to 1,000 eggs. The eggs are positioned securely in a web, which remains in the tarantula burrow, and guarded by the female. Eggs hatch in 45 to 60 days. Once spiderlings leave the egg sac, it's not unusual to stay with the females for up to a week or possibly longer before dispersing to make their own burrows.
Females have been known to live up to 30 years. But considering no studies have lasted so long, the lifespan is presumed to be longer. Males rarely live over 1 year...
