(Pallas, 1793) [1]

Unlike other species of tadpole shrimp, Lepidurus arcticus is known to coexist with fish, such as Arctic char,[4] brown trout[6] and European whitefish.[5] Furthermore, they exist in water temperatures much colder (4–7 °C or 39–45 °F) than the other species of its order.[9] About 14 °C seems to be the upper thermal threshold for where in which waters it can live.[10] It is a common predator of Daphnia pulex.[11]
