Agree. I think most fish are beautiful in a way, even the "ugly ones".

What I really love about the fish under discussion here is, for a long time they had no clue why some rainbow trout became steelhead, and some didn't. (They still don't know 100%) Such an interesting story, and a regular rainbow and a steelhead just seem almost like another species - different size, behavior and even taste when you eat them.

You want to have fun, get two fresh water fish biologists in a room and ask them if steelhead and rainbow trout are different species. Everyone has a different opinion they believe in passionately.

People for a long time didn't know what the reproductive cycle of eels is like, because they travel all the way from the Atlantic ocean and back while maturing, so nobody had ever seen a juvenile. Too bad they're critically endangered.

Thank goodness Freud searched for those eel dicks.
