Texas Cave Life

Texas caves are the home to a number of different and interesting cave related species. Some of the species such as the Raccoon visit the cave from time to time, however, they largely live outside. Others such as the cave cricket live in the cave but come out at night to eat. The rare cave beetle, the Rhadine Persephone never leaves the cave.
Here are a few of the Texas cave creatures.
