Branchinecta paludosa is a species of freshwater fairy shrimp[1] with a Holarctic distribution.

[2] B. paludosa is widely distributed in the Arctic tundra of Eurasia, chiefly above latitudes of 60° north.

[3] It reaches its northern limit, 77° north at Ivanov Bay in the Novaya Zemlya archipelago.

[4][5] Further populations exist as far south as the Tatra Mountains on the Polish–Slovakian border at about 49° north.

[3] After hatching, young B. paludosa spend 20–30 days as larvae, before reaching sexual maturity between the end of July and middle of August.
