Tampa pet store

My local Tampa pet store offers an unusual pet: spiders. Spider, the common name for about 34,000 species of arthropod animals having eight walking legs, anterior appendages bearing fangs and poison glands, and specialized reproductive organs on the second appendages of the male. They commonly make extensive use of silk that they spin. Like other arachnid species, spiders are terrestrial, although a few have adapted to freshwater life by trapping air bubbles underwater and carrying the bubbles with them. Spiders are numerous and occur worldwide. Although most are less than 0.4 in long, the largest has a body length of about 3.6 in, and spider leg spans can be much greater. On the abdomen are located modified appendages, the spinnerets, used in secreting silk. Spiders are generally carnivorous and feed only on living prey. They can crush it with processes on the pedipalps, and the chelicerae almost always have glands that can inject venom. The bite of some large spiders can be painful, but most species are too small to break human skin, and only a few are dangerous to humans. The latter are mainly the black widow spider and its close relatives, which are non-aggressive and bite humans only in defense. Their painful bite is followed by faintness, difficulty in breathing, and other symptoms; although the bite is seldom fatal, especially if it is inflicted on healthy adults, medical attention for it should be sought at once. The digestive system of spiders is adapted exclusively to taking up liquid food, because the animals generally digest their prey outside the body and then suck the fluid. The fairly complex brain is larger or smaller in certain parts, depending on whether the animal locates prey mainly by touch or vision.
