Looking for Tarantulas

I wish I photoed a tarantula; not yet! I will keep my eyes open for the 3-4 inch tarantulas that grow here in the Sonoran Desert.

I did walk past a tarantula’s web the other day, but no 8-legged creature was seen by me! Tarantulas are nocturnal hunters and spend a lot of time in their burrow so I guess I am not surprised to not see one.

Desert tarantulas live in a deep burrow and line the entire floor of their enclosure with silk and surround their entrance with a silken “welcoming mat”. Tarantulas do not have great eyesight so the “welcoming mat” helps when it vibrates like guitar strings, yet it is not for capturing prey. Unlike other spiders with webs to catch insects, tarantulas take on an active approach to feeding by subduing and killing the prey themselves. When the tarantula is alerted to the presence and location of the intruding beetle, grasshopper, small lizard or mice, it will attack and kill by injecting venom through its fangs into its prey. Since they have no teeth, it is the venom that liquefies the prey and the tarantula uses its sucking stomach to draw in the meal.

Who keeps the tarantula population in check? Coyotes and foxes.

There are 4 dozen species of tarantulas in the USA and Mexico, so hopefully at some point I can capture a photo of one. In the meantime, keep an eye open for more “welcoming mats”!
