Texas Brown Tarantula (Aphonopelma spp.)
Manchaca, Texas (23 March 2007)

Photography by Laurie Anne D.

The species cannot be determined from this specimen, but its location, its basic anatomy, and its uniform brown color, makes it a member of the genus Aphonopelma.  The fourteen species of this genus that are native to Texas look very much alike, but differ in microscopic aspects that are not discernible with ordinary vision.

The carapace is large and leathery in appearance. Legs are stout and hairy, and the abdomen is covered with thick, brown, often urticating (capable of producing allergic or irritating reactions in susceptible individuals) hairs.

When threatened, this tarantula turns to face the threat, lifts its front legs in a threatening posture, and articulates its fangs in preparation for biting.  Despite its fierce appearance, the bite is not considered dangerous, and tarantulas make excellent pets when properly cared for and handled with care.  Females of this genus often live as long as 25 years in captivity, though males live no more than a few months.

Tarantulas migrate at certain times in the year, during which time they may turn up just about anywhere in Texas

Many thanks to Laurie Anne for these photos....
