It has recently come to my attention that there is a fish called a dolphin, and it is also known as mahi-mahi or dorado.
Why in the world would they name a fish the same name as a completely different animal?
In trying to decipher what was going on, I found several… ahem… interesting websites.
One claimed that it is related to the dolphin, but is not a mammal.
Many (including this one) claimed that is is a dolphin as compared to a porpoise.
Now, I’m pretty sure that (mammal) dolphins are distinct from porpoises, right? I’m guessing that because most of the sites were either about cooking or catching them, they weren’t interested in such distinctions.
Here’s a fairly good description of it.
But the question remains. Why name a fish a dolphin?
