Females of many species care for their young, for example by carrying them around or by sharing food with them. Tarantulas also have silk glands in their feet.
Their abdomens bear appendages that have been modified into spinnerets that extrude silk from up to six types of glands. Ceology and Distribution of Spiders in Southwestern Nigeria.
trur After a kill, some ant-mimicking spiders hold their victims between themselves and large groups of ants to avoid being attacked. Stimson; Jackson, Robert R. Their greater success may be because sphecid waspswhich are often the dominant predators of spiders, much prefer to attack spiders that have flat webs. In some cultures, spiders have symbolized patience due to their hunting technique of setting webs and waiting for prey, as well as mischief and malice due to their venomous bites.
There are many common phobias, but surprisingly, the most common phobia is arachnophobia. In conclusion, 19 different spider families are recorded in Obafemi Awolowo University, Nigeria, during this study.

The Book of the Spider: Retrieved 31 October — via Google Books. It is estimated that the world’s 25 million tons of spiders kill — million tons of prey per year. Since many spiders are nocturnal, ttrue extent of nectar consumption by spiders may have been underestimated.
Other differences between the principal and secondary eyes are that the latter have rhabdomeres that point away from incoming light, just like in vertebrates, while the arrangement is the opposite in the former. Cultural depictions of spiders. Spisers genera such as TetragnathaLeucaugeArgyrodes or Theridiosomaguanine creates their silvery appearance. It is initially a liquid, and hardens not by exposure to air but as a result of being drawn out, which changes the internal structure of the protein.
Unlike most arthropods, spiders have no extensor aransomorphae in their limbs and instead extend them by hydraulic pressure.
Classification is based on Shultz Items in green are possibly paraphyletic groups. They achieve this by a telephoto -like series of lenses, a four-layer retina and the ability to ghe their eyes and integrate images from different stages in the scan. These hairs are fine setae bristles with fragile bases and a row of barbs on the tip.
Many spider species are colored so as to merge with their most common spdiers, and some have disruptive colorationstripes and blotches that break up their outlines. Annual Review of Entomology, 18, Gods, Demons and Symbols of Ancient Mesopotamia: Arachnophobia, or fear of spiders, is one of the most common specific phobias.

Varying placement of webs allows different species of spider to trap different insects in the same area, for example flat horizontal webs trap insects that fly up from vegetation underneath while flat aarneomorphae webs trap insects in horizontal flight.

Therefore, cultivated habitat hosted the largest number of spider families in the area of study while house dwellers hosted the least number of araneomorphaae families. The Mygalomorphae, which first appeared in the Triassic period,  are generally heavily built and hairy, with large, robust chelicerae and fangs. The Life of the Spider.
