Anaspidesidae is a family of freshwater crustacean that is endemic to Tasmania, Australia.
This group of crustaceans are considered living fossils.
[1] They are commonly and collectively known as the Tasmanian anaspid crustaceans.
However, genus name Anaspis was preoccupied by the insect genus, Anaspis Geoffroy, 1762,[3] and therefore, in 2017, the family was renamed to Anaspidesidae by Shane Ahyong and Miguel A.
[3][4] Anaspiesids have stalked eyes, long antennae and antennules, and a slender body with no carapace.
