Harold von Braunhut[1] claimed that “The species now grown in labs and widely used in today’s Sea-Monkey kits are called Artemia NYOS (for New York Ocean Science). They are hybrid species of brine shrimp within the genus Artemia, but you can just call them Super Sea-Monkeys”. However, the claim is hearsay quoted by Tim Walsh in his book “Timeless Toys: Classic Toys and Playmakers who Created Them” allegedly from an interview with Harold.[2] The creation of a new species is a scientific claim and today there is no scientific proof or public documentation for this claim. A scientific claim is made through a peer review process within a scientific organization. We cannot ask Harold or Anthony directly since Harold died at the age of 77 on Nov. 28 2003 at his home in Indian Head, Md.,[3] and Anthony D’Agostino, Marine Biologist, died on June 20, 2017 at Stony Brook University Hospital at the age of 86.[4] This claim may be just an Urban Legend about Sea-Monkey.
