Daphina

Daphnia, commonly known as water fleas, are oftentimes found in vernal pools. Belonging to the taxonomic order Cladocera, these small planktonic crustaceans earned their common name from their swimming pattern, which resembles a jumping flea. Distinguishing anatomical characteristics for Daphnia include a bivalved carapace, pair of antennae which is used for swimming, and compound eyes. These crustaceans are filter feeders and continually move their legs, five or six pairs which are located in the ventral gap in the carapace, to collect fine particles of zooplankton, algae, or detritus. Once the particles are collected a bolus, or small ball, is formed from these materials and ingested. The outer carapace covering is usually transparent which allows for one to observe the beating heart, digestive system, and any eggs which may be present. Daphnia also serve are a main food source in a vernal pool ecosystem as aquatic invertebrates and salamander larvae rely on this species for survival. More . . .
