What are Sea Monkeys?
Sea monkeys are tiny living creatures that look like small swimming dots in water and are often sold as pet kits for kids. Even though the name sounds magical, sea monkeys are actually a type of brine shrimp, a real aquatic animal that has existed on Earth for millions of years.
They hatch from eggs when added to water, grow slowly, and swim using small leg-like appendages. Their unusual movement and long tails make them appear playful—almost like tiny underwater acrobats.
What Are Sea Monkeys Made Of? (The Real Science)
👉 Sea monkeys are brine shrimp (Artemia).
Brine shrimp are:
- Crustaceans (related to shrimp and crabs)
- Microscopic when young
- Able to live in salty water
- Famous for surviving harsh conditions
Their eggs, called cysts, can stay dormant (asleep) for years—sometimes even decades—until they are placed in water.
Why Are They Called “Sea Monkeys”?
This is one of the most searched questions about sea monkeys.
Sea monkeys were given this name for marketing reasons, not scientific ones.
They are called sea monkeys because:
- Their long tails look like monkey tails
