Ecology: Instream habitat: Fairy shrimps occur in temporary freshwater’s including, pools, ditches, rock holes, and ponds.
Feeding ecology: Anostracans are planktonic filter feeders, using a groove between the bases of the thoracic legs to filter microscopic organisms from the water.
Habit: Anostracans characteristically swim with their ventral surface uppermost.
Life history: Males use the enlarged antennae to grasp females during copulation. Eggs are resistant to desiccation and are activated by the presence of water. Branchinella can develop from resting eggs to a dense population quickly after inundation. Nuisance blooms can occur.
