How Long do Sea Monkeys Live?

Sea Monkey

Most people have heard of sea monkeys, but not everyone knows how long these little creatures actually live. Here’s a short overview of sea monkey biology and how long you can expect your sea monkeys to live.

Sea Monkey Biology

Sea monkeys are a type of brine shrimp that can be found in salt lakes around the world. Unlike other types of shrimp, sea monkeys have the ability to go into a state of suspended animation when conditions are not ideal for their survival. This means that they can effectively “hibernate” until the conditions improve.

As a result of this unusual biology, sea monkeys have a lifespan that is much longer than other types of shrimp. In fact, sea monkeys can live for up to 5 years in captivity! However, the average lifespan of a sea monkey is somewhere between 2-3 years.

How to prolong your Sea Monkey’s life

There are a few things you can do to help your sea monkeys live long and prosperous lives.

  • First and foremost, it’s important to provide them with a clean and spacious tank. A larger tank will give them more room to swim and explore, which will help reduce stress levels.
  • Second, be sure to feed your sea monkeys a diet that is high in calcium. This will help keep their shells strong and prevent disease.
  • Finally, avoid overfeeding your sea monkeys as this can lead to health problems down the road.


With proper care and attention, your pet sea monkeys can enjoy long lifespans of up to 5 years! By providing them with a spacious and clean tank, feeding them a nutritious diet, and avoiding overfeeding, you can help ensure that your beloved pets have happy and healthy lives.
