Boeckella palustris is a species of copepod that lives in South America. It inhabits shallow pools, including the highest body of water ever to have yielded a crustacean, at an altitude of 5,930 m (19,460 ft) in the Andes. It was described independently by two scientists in 1955, using material brought back by different European expeditions to the same region.
Males of B. palustris are 1.5–2.3 millimetres (0.059–0.091 in) long, and females 1.9–2.8 mm (0.075–0.110 in). The antennules are relatively short.B. palustris can be distinguished from other members of the genus Boeckella by the form of the fifth leg in males.
Boeckella palustris has a Páramo–Punan distribution, being found in southern Peru, and close to the border between Bolivia and Chile. It lives in "small, shallow bodies of water", a habitat it shares with Boeckella calcaris.
Boeckella palustris shares the record for the crustacean living at the highest altitude with the fairy shrimp Branchinecta brushi; both were found on December 13, 1988 in the same pool at an altitude of 5,930 metres (19,460 ft) near the summit of the stratovolcano Cerro Paniri (22°05′S 68°15′W / 22.08°S 68.25°W) in the Antofagasta Region of Chile. The only higher record, which claimed that Branchinecta paludosa occurred at 97,000 feet (30,000 m) is "almost certainly a typographical error".
