The name was changed to the more fanciful version in 1962, and they were marketed heavily to kids — especially through comic books, and magazines for kids, where they appeared alongside other gimmicks like X-ray glasses.
The product was a huge success, despite the fact that the Sea-Monkeys — in reality, brine shrimp — disappointed millions of kids by not looking even remotely like the characters on the product package. (At the bottom of many of the ads, it did say “Caricatures shown not intended to depict Artemia salina,” but how many kids read the fine print?)

Shrimp that play games
From the Austin American-Statesman (Texas) November 1, 1976
One of the most unusual aquatic pets is the strain of artemia (brine shrimp) that Harold Braunhut has developed and marketed as Sea Monkeys.
A starter set can cost as little as a dollar. The little shrimp hatch instantly in 12 ounces of purified water, are born about the size of this comma, and within four weeks they grow to about 1/3-inch, with feathery little tails and swimmerets. Fully grown, they reach a maximum of two inches.
Sea Monkeys would be little more than a curiosity, except for a unique talent: They react to light and swim upstream against currents.
Braunhut has used these characteristics to create an instruction book of fascinating tricks to put the shrimp through, and his Transcience Corp. markets a series of racing games in which human players guide their Sea Monkeys by controlling the rate of the current flow.
A deluxe set to breed 100 shrimp includes the instruction book, good for several months, and ready-to-hatch dry eggs and retails for around $2. The racing games (speedway, ski trails, cycle race, fox hunt) are $10 each.
