usually rare invertebrates, such as the Cladocera Eurycercus glacialis, to thrive. Other Cladocera common in turloughs include Alona affinis, Alonella excisa, Chydorus sphaericus, Eurycercus lamellatus and Simocephalus vetulus. A number of beetles that are rare or absent elsewhere in Ireland can be found in turloughs, such as Hygrotus quinquelineatus, Coelambus impressopunctatus, Graptodytes bilineatus, Agabus labiatus, and A. nebulosus. Other invertebrates can also occur, such as fairy shrimp, flatworms and snails.
