As omnivores, shrimp consume many different kinds of animal and plant species, but primarily feed on small fish, algae, plant particles and plankton. They will also eat decaying plants and will scavenge parts of dead animals such as snails, clams and fish, and will even eat other shrimp.
With over 2,000 known species, shrimp are found in almost every aquatic environment in the world, whether it is salt, brackish or fresh water. Shrimp travel together in schools and live on ocean floors and river beds throughout the world. They are classified as having a conservation status of "protected" and typically live for one to two years. The most common predators they face every day are crabs, fish and whales.
