Okay you brainiacs, here's a question I am puzzling over. I have read that hooligan are a type of smelt, and I thought capelin are as well. And then Alaska also has rainbow smelt and longfin smelt. The question is this: how come there is no similarity in their latin names? Or am I mistaken in my belief that they are all smelt?
Capelin: Mallotus villosus
Hooligan: Thaleichthys pacificus
Rainbow smelt: Osmerus mordax
Longfin smelt: Spirinchus thaleichthys
Also, are these the only smelt produced in Alaska or are there others?
