Troglocaris

Genus of crustaceans

Troglocaris is a genus of freshwater shrimp in the family Atyidae. These stygobitic, whitish and eyeless shrimp are found in Southern Europe. Although locally very common, the small ranges of the individual species make them highly vulnerable to habitat loss, for example by water extraction. Their underground habitat is often extremely stable; for example, the Vipavska jama cave in Slovenia is home to a population of T. anophthalmus, and its water only varies from 10 °C (50 °F) in the winter to 11 °C (52 °F) in the summer. In some Dinaric caves, notably Vjetrenica, as many as three species may occur together.
