Is a sea monkey real life animal?

Sea monkeys, also known as brine shrimp, are real-life animals. They are small crustaceans that live in saltwater. Brine shrimp can grow to a maximum size of two centimeters and have a lifespan of up to two years. They are found in various habitats, including salt lakes, coastal lagoons, and shrimp farms. Sea monkeys are used as a live food source for aquarium fish and for research purposes. They can be bought as kits, containing cysts that can be hatched in saltwater. As they grow, the brine shrimp feed on algae and other microscopic organisms.
