Sake in which Sea Monkeys hatch?

When I was a schoolchild, Sea Monkeys (small arthropod resembling a shrimp: Artemia salina) were sold by mail order. I hear that the actual product was a breeding kit including dried spawn of this creature, necessary feed, etc. I often saw advertisements for this product printed on the back covers of juvenile weekly magazines, but I'm not sure how popular it was among children.

The company selling this product hyped the Sea Monkey as a mysterious and monstrous creature, but it just looked like a tiny shrimp and never looked like a monkey in spite of its product name "Sea Monkey."

These days, I hardly hear the word "Sea Monkey," but I recently happened to get this word for the first time in long years.

At that time, I was drinking sake with friends at a table of the rest station run by Ozawa Syuzou. First, we get warmed regular sakes at the shop and shared them. Later, one guy opened the 1800-ml bottle he bought at the souvenir shop, and he gave us the sake. This sake was Sawanoi Kameguchishu Junmai Ginjirushi.

When we were drinking this sake, the guy who gave it to us said, "They look like Sea Monkeys!" The winter sunlight was penetrating into the sake bottle placed on the table. This sake was sparkling namazake (unpasteurized sake) and a lot of small bubbles was slowly rising up in the sake and shining in the sunlight. He meant that they looked like Sea Monkeys. Actually, I have never seen this creature with my eyes, but Sea Monkeys probably look like these small bubbles.
