"The most remarkable organs perceptable on the abdomen of the spiders are the <em>spinnerets</em>, by means of which they spin their curious and often beautiful webs, which have attracted the attention and excited the admitation of mankind in all ages. These spinnerets are little teat-like organs, placed close to the extremity of the abdomen, on its lower surface." &mdash; Goodrich, 1859

"The Tarantula is a large spider, with a body about an inch in length; its bite was formerly supposed to produce Tarantism, and doubtless in some cases, produces disagreeable symptoms. It is a native of Italy, but varieties, or closely allied species, are found throughout the S. of Europe. The tarantulas of Texas and adjacent countries are large species of Mygale."&mdash;(Charles Leonard-Stuart, 1911)

Spiders (order Araneae) are air-breathing chelicerate arthropods. Trapdoor spiders, of family Ctenizidae, are medium-sized mygalomorph spiders that construct burrows with a cork-like trapdoor made of soil, vegetation and silk. The Trapdoor Spider is difficult to see when it is closed because the plant and soil materials effectively camouflage it. The trapdoor is hinged on one side with silk. The spiders, which are usually nocturnal, typically wait for prey while holding onto the underside of the door with the claws on their tarsi. Prey is captured when insects, other arthropods, or small vertebrates venture too close to the half-open trapdoor at night. The spider detects the prey by vibrations and when it comes close enough, the spider leaps out of its burrow and captures it.

"Restoration of Triarthrus Becki, Green, as determined by Beecher from specimens obtained from the Utica Slates (Ordovician), New York. A, dorsal; B, ventral surface. In the latter the single pair of antennae springing up from each side of the camerostome or hypostome or upper lip-lobe are seen. Four pairs of appendages besides these are seen to belong to the cephalic tergum. All the appendages are pediform and bi-ramose; all have a prominent gnathobase, and in all the exopodite carries a comb-like series of secondary processes." &mdash; The Encyclopedia Britannica, 1910
