Ellen Clark (1915–1988) was an Australian carcinologist and naturalist, whose work focused on crustaceans and ants[1][2][3] Clark studied, named, described and published many of the Australian freshwater crayfish species.
[4][5] By 1939, she was reported to have identified more than half the known species of Australian crayfish.
[6][7][8][9] She conducted research about blood groups in crustaceans and made a significant contribution to the study of crayfish genera.
[10][11][12] She was the first woman to publish in the Memoirs of the National Museum of Victoria.
[13] Clark's work has had a lasting legacy and is still being debated in scientific papers.
