[2] In the UK, there are just two known populations: in a pool and adjacent area in the Caerlaverock Wetlands in Scotland, and a temporary pond in the New Forest.

[5] The putative Lower Permian subspecies from France has also been redescribed as a separate notostracan taxon, Heidiops permiensis.

The latter is a very rare reproductive mode in animals, in which populations are made of hermaphrodites, with a small proportion of males.

Fertilized females or hermaphrodites produce diapausing eggs or cysts, able to survive decades in the sediment of the ponds and lakes they inhabit.

In 1801, Louis Augustin Guillaume Bosc made the first officially recognised species description of Triops cancriformis.

In 1909, Ludwig Keilhack used the correct name "Triops cancriformis (Bosc)" in a field identification key of the freshwater fauna of Germany.
