Spider behavior Spider behavior Spider behavior refers to the range of behaviors and activities performed by spiders. Spiders are air-breathing arthropods that have eight legs and chelicerae with fangs that inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all other groups of organisms which is reflected in their large diversity of behavior. Almost all known spider species are predators, mostly preying on insects and on other spiders, although a few species also take vertebrates such as frogs, lizards, fish, and even birds and bats. Spiders' guts are too narrow to take solids, and
Ticks of domestic animals or more, respectively, whilst questing on the vegetation. Thus it is usually not practical to control them by pasture management. In addition, farmers find the priority to provide their stock with good feed often conflicts with the regimes for pasture rotation for tick control. Ticks affecting dogs and other companion animals around private houses are reduced by clearing of vegetation and leaf litter, mowing grass short, and fencing out deer and other wild animals that bring in ticks. Compared to other arthropods of veterinary and medical importance most species of ticks are long-lived over their whole life-cycle. "Ixodes" species in
