History of National Sea Monkey Day
The history of Sea Monkeys began in 1957 when Harold von Braunhut discovered brine shrimp, Artemia salina, being sold as pet food. Partnering with marine biologist Dr. Anthony D’Agostino, he developed a special formula to create an environment for these shrimp to thrive. Initially marketed as “Instant Life,” they were later renamed “Sea Monkeys” due to their tail’s resemblance to a monkey’s tail. Their popularity soared in the 1960s, thanks to creative comic book advertising.
