# Niphargus

Niphargus Schiødte, 1849 è un genere di piccoli crostacei ipogei (che vivono nelle grotte e nelle falde acquifere), simili nell'aspetto ai gamberetti, diffusi in Eurasia.

## Descrizione

Come la gran parte degli organismi troglobi, i crostacei del genere Niphargus sono privi di occhi e di colore bianco.

## Distribuzione e habitat

L'areale del genere si estende in Europa, dalla penisola iberica a ovest e dalla Gran Bretagna a nord, sino all'Asia Minore e al Medio Oriente. L'Italia, con oltre 60 differenti specie note, è uno dei centri di maggiore biodiversità.
Molte delle specie del genere Niphargus sono endemismi con areale molto ristretto, addirittura a singole grotte. Ad esempio Niphargus costozzae (endemica dei Covoli di Costozza, nei Colli Berici, descritta per la prima volta nel XX secolo da Schellenberg) oppure il Niphargus galvagnii (nella grotta di Castello Tesino, in Trentino).
