Troglocaris anophthalmus
Troglocaris anophthalmus
''Troglocaris anophthalmus'' is a species of freshwater shrimp in the family Atyidae. It lives in karstic caves in Bosnia and Herzegovina, Croatia, Italy and Slovenia. Although morphologically similar across its 500-kilometre range, molecular phylogenetics suggests that there are four or five cryptic lineages with more restricted ranges, although one such lineage does range unusually widely for a troglobite – over 300 kilometres .
Like other underground-living animals, this shrimp lacks pigment and eyes. The carapace length is typically about 0.5–0.9 cm .
It was originally described by Vincenz Kollar as ''Palaemon anophtalmus'' , but this name was considered to be a ''nomen nudum'' for a long time. This name is, however, accompanied by a description, and predates Dormitzer's junior synonym ''Troglocaris schmidtii''.
