Sea-Monkeys
Initially, Sea-Monkeys were called “Instant Life.” But its name was soon changed to match their salt-water habitat. It was also the perfect name because of the resemblance of the animals’ tails to actual monkeys. In case you didn’t know, Sea-Monkeys were a type of shrimp sold in the form of eggs. They became popular with children in the ’60s and ’70s, thanks to some smart comic book marketing. These things also caught the attention of NASA’s John Glenn, who took some into space with him.
