Present day endemic aquatic fauna includes amphipods, hemipterans and springtails. The diet consists of various arthropods, including mites, springtails, ants, and insect larvae. Many invertebrates thrive in snow, including spiders, wasps, beetles, snow scorpionflys and springtails. Below ground, nematodes and springtails also consume fungal tissue. Therefore, their diet includes tiny springtails, midges, and aphids. Examples include chemotrophic bacteria, some species of flatworms, springtails, and cavefish. Crickets, spiders, pseudoscorpions, mites, and springtails may live their full lifecycles in the cave. They feed on fruit flies, small crickets, moths, and springtails. The goldcrest takes a wide variety of prey, especially spiders, caterpillars, bugs, springtails and flies. Examples include fleas, springtails, and Thysanura. They are found among rocky debris, feeding on tiny, stray springtails and flies. Juveniles have a similar diet but include flies and springtails. The Collembola (or springtails) are very abundant in terrestrial environments. Sminthurides is a genus of globular springtails in the family Sminthurididae. Folsomia is a genus of elongate-bodied springtails in the family Isotomidae.
