Sea horses! A big thing for kiddies in the late 50s.
I call BS on this. Shrink in size of species tends to be a product of scarcity of food. (For example see North Korean’s decline in average height).
If temperature had anything to do with it then why are African Elephants still so large today?

I remember sea monkeys being advertized for years.
