 in the 2014 Nikon Small World Photomicrography competition was awarded to Dr. Robert Siwanowicz for this stunning confocal image of a brine shrimp. Brine shrimp are a popular research organism in laboratories because of the ease of rearing and producing large numbers in small spaces at low cost. Brine shrimp are often used to test the effect of chemicals on aquatic organisms. They are one of several arthropods that have been selected for space travel.

Brine shrimp are crustaceans that inhabit saline inland lakes. Under adverse conditions, they can produce eggs that can be stored dry for over a year. This property allows them to hitch rides on other animals and colonize new lakes. Brine shrimp are a food source for fish and produce high densities only in the absence of fish predators. Aquarium hobbyists find brine shrimp to be a good live food for tropical fish.
