A tarantula has four pairs of legs and two additional pairs of appendages. Each leg has seven segments which, from the prosoma out, are: coxa, trochanter, femur, patella, tibia, tarsus and pretarsus, and claw. Two or three retractable claws are at the end of each leg. These claws are used to grip surfaces for climbing. Also on the end of each leg, surrounding the claws, is a group of hairs. These hairs, called the scopula, help the tarantula to grip better when climbing surfaces like glass. The fifth pair are the pedipalps which aid in feeling, gripping prey, and mating in the case of a mature male. The sixth pair of appendages are the chelicerae and their attached fangs. When walking, a tarantula's first and third leg on one side move at the same time as the second and fourth legs on the other side of his body. The muscles in a tarantula's legs cause the legs to bend at the joints, but to extend a leg, the tarantula increases the pressure of blood entering the leg.
FANTASTIC shot! Look at all those little bristles...
Can you feel the pain? Can you taste the cold creepy vibration running from the base of your backbone to the rear of your neck?
You can't? Oh well, try to imagine eight legs like the one in this photo moving on your back's naked skin....
Try to stand still and reflect on how is it possible that a little creature like an harmless spider can awake our disgust or terror....
It's amazing that it's possible, and maybe it is the same reason why we feel in peace when we look at the sea in the evening... maybe, could it be the remains of that wild/animal part of every one of us that claims it's rights on our life?
think about it sometimes, think about this just before crushing an ant or any other bug under your shoe... (yes, including mosquitoes)
Awesome shot as well!
