Daphnia is a genius of small crustaceans that live in fresh water. Daphnia are important for food to fish and other aquatic organisms. They are also important in detecting changes in water chemistry because of their sensitivity.
Daphnia are transparent in color and have one compound eye and one eyespot. They also have two pairs of antennae: one for olfactory, and another for swimming. They also have "armor" for protection against predators. The "helmet" and tail spine usually arise when daphnia live in environments with predators.
This specimen was found in a sample from Proctor Lake, taken with a zooplankton net in an area where the depth was about 13 feet deep.
