National Sea Monkey Day – May 16, 2022

National Sea Monkey Day falls on May 16 every year to celebrate these little creatures. Sea Monkeys were created in a lab many years ago but since then they’ve become a common household pet. Many of us have happy memories of awaiting the delivery of our first Sea Monkeys in the mail. They are really popular with children and adults alike and, at one point, they were even heavily marketed by comic books.

History of National Sea Monkey Day

It was back in 1957 when, during a visit to a pet store, Harold von Braunhut became fascinated with a species of brine shrimp called Artemia salina, which was being sold as pet food. He later partnered up with a marine biologist, Dr. Anthony D’Agostino, to bring the sea monkey to life. Together, they developed a proper mix of nutrients and chemicals in dry form that can be added to plain water to create an environment conducive to the shrimp’s growth.

Sea Monkeys were initially sold under the name ‘Instant Life’ and later given the name ‘Sea Monkeys’ owing to the fact that they have a monkey-tail-like shape, making them resemble monkeys of the sea rather than shrimps. They were a very popular pet from the ’60s onwards and they usually came with a special mini aquarium that was used to hatch them and for them to live and grow in.

These small creatures have gained much popularity over the years and even found a name in pop culture. They’ve been showcased in television shows including “South Park,” “The Simpsons,” and “Desperate Housewives.”
