People do not usually think about spiders when they think about endangered species. Endangered species are animals that are in danger of dying out. Spiders are small and have lots of babies. People think that this means they cannot die out. This is not true. One endangered spider is the Kauai cave wolf spider. It is only found in a few caves on an island of Hawaii. This spider's main kind of food is hard to find. This is one of the reasons why there are so few of these spiders. Another reason is that the female might lay as few as fifteen eggs at a time. Most female wolf spiders lay many more eggs at a time. Many other spiders are endangered for the same reason.

What is the main idea of the passage?

Only six populations of the Kauai cave wolf spider, also called the blind spider by locals, are known to exist. They are only known to occur in a small number of caves within a lava flow that covers an area of 10.5 km2 in the Kloa-Poip region of Kauai, Hawaii.There are currently only six populations of the endangered Kaua'i cave wolf spider, also known as the blind spider by locals, which is native to Kauai's Koloa Poipu region in the Hawaiian Islands.

The Kauai cave wolf spider has vivid orange legs and a reddish-brown carapace, as well as a total length of 12.7 to 19.0 millimeters (0.5 to 0.75 inches).

The Kauai cave amphipod, Spelaeorchestia koloana, one of its main prey species, is only known from nine populations and grows to a maximum length of 10 mm (0.4 in). These eat decaying plant material. In 1973, a wolf spider was found in a cave on Kauai. Loss of habitat and degradation of the species' cave are the main threats it faces 1973. The primary threat to the species is habitat loss and degradation brought on by human activities connected to development and agriculture in its cave habitat. Chemical and biological pest controls, which are frequently used to get rid of insects like ants and cockroaches, have also put them in danger.
