Branchinecta brushi is a species of fairy shrimp found at an altitude of 5,930 m (19,460 ft) in the Chilean Andes.
The type specimens of B. brushi were collected on December 13, 1988 by Charles F. Brush during an attempt to break the world record for the world's highest SCUBA dive. This attempt took place in a small pool, 12 by 6 metres (39 ft × 20 ft) across, 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.
B. brushi was collected, along with some other species, from below 5 centimetres (2.0 in) of ice. The specimens were stored in 70% ethanol at the Peabody Museum of Natural History and the United States National Museum for nearly 20 years before being re-examined; the species was eventually described in 2010, and given the specific epithet brushi to commemorate Brush.
Males are 10–16 millimetres (0.39–0.63 in) long, while females are only 9–13 millimetres (0.35–0.51 in). In common with other fairy shrimp, the males bear complex structures on their second antennae, which are used in mating.B. brushi closely resembles Branchinecta valchetana, from which it differs in the form of the antennae and the gonopods.
