Eurycercus longirostris
Eurycercus longirostris is a Holarctic cladoceran crustacean first described by Hann in 1982. A 2011 taxonomic revision synonymized E. vernalis with E. longirostris due to lack of morphological and genetic justification for their separation. The species has a broader distributional range than previously recognized and belongs to the subgenus Eurycercus (Eurycercus). As a member of the Eurycercidae family, it shares characteristics with other chydorid-like cladocerans including a rounded carapace and specialized feeding appendages.
