Tooth Cave Spider Facts - Photos - Earth's Endangered Creatures

The tooth cave spider the smallest of all known invertebrates and only found in the Edwards Plateau located in Travis County of Texas. Adults grow less than two millimeters in length. It is pale and cream in color and has long legs, and it has six eyes that are hardly visible.

The tooth cave spider can only thrive on the walls and ceilings of caves. It feeds on tiny microarthropods that are caught by hanging from a small tangle or sheet web using its long, thin legs. Its reproductive behavior is unknown.

The current population is estimated as less than 250. This species is threatened by loss of habitat due to urban development. Many of the caves that the species once dwelled in have been paved over or filled in, and contamination by pollutants have also posed a threat to the survival of the species. In an effort to save the species, a recovery plan has been developed which consists of further surveying, researching, protecting, and managing several caves where surviving populations are located.

Eight Species Declared Extinct But May Still be Out There

1. Tasmanian Tiger
The Tasmanian tiger is endemic to Australia. Although this species is called tiger (named for its stripes) and wolf (due to its canid-like appearance), it is not a member of the cat or wolf family. It is a member of the marsupial family. Other members of this family include kangaroos and koala bears.

The last known Tasmanian tiger died in a zoo in Hobart, Tasmania in 1936, but there have been hundreds of unconfirmed sightings, and a reserve has been set up in Southwestern Tasmania in the hopes that possible surviving individuals can have adequate habitat.
