Artemia, commonly known as brine shrimp, are small aquatic crustaceans that live in salty water bodies like salt lakes and salt ponds. They have a simple body structure with a segmented body, compound eyes, and feathery legs used for swimming and filtering food particles from the water. Artemia can survive in extreme conditions with high salinity where most other animals cannot live. They are often used as live food in aquaculture and aquarium industries because they are rich in nutrients and easy to culture. Artemia also produce dormant eggs called cysts that can survive drying and hatch when placed in water again.
