Sea-Monkeys are a trademarked brand given to a variant of brine shrimp or Artemia salina. These cute critters were first marketed in 1957 by Harold von Braunhut (who also invented X-Ray specs) as "Instant Life". The name was changed to the much cuter sounding to "Sea-Monkeys" in 1962. The name "Sea-Monkeys" was chosen because of their playfulness, like monkeys. Exaggerated advertisements and packaging depicted smiling creatures, underneath these pictures was a disclaimer that stated, "Caricatures shown not intended to depict Artemia."
