Spider adaptations include sticky webs, venom, quick movement and various anatomical adaptations. The specific adaptations that help spiders survive depend on the species. Some spiders have developed additional coloration adaptations, such as warning colors or camouflage, while others have developed behavioral adaptations.Know More
Most spiders spin sticky webs which they use to capture insects. Their venom paralyzes the prey. Spider venom also works as a digestive enzyme, which dissolves the insides of the prey, allowing spiders to drink the nutrients. The venom can also work as a preservative. In this case, spiders can wrap the insect in their web for storage and later consumption.
Spider anatomy allows for locomotive adaptations. Because of their eight legs made up of seven segments each, spiders can move quickly and adeptly. Certain spiders, such as the common house spider, have special adaptations to their hind legs. They have six to 10 comb-like bristles that they use to fling their silk over their prey to wrap and preserve their victims.
Funnel web spiders, on the other hand, have adapted to the harsh desert conditions of Australia. Rather than rely on webs to trap prey, they aggressively attack other insects. Sturdy, powerful legs aid this adaptation, as do the small hairs that grow all over their legs and bodies.
Some spiders, such as sand spiders, have developed camouflage colors so that they blend into their surroundings. Others, such as the black widow, have bright warning coloration, which scares off other organisms.Learn more about Spiders
