On the Origins of Freshwater Amazonian Stingrays

  • We are currently upgrading MFK. thanks! -neo
good Read, and like others have said. These types of discussions I like, however like coyotethug says hte people with the most knowledge dont share here. However I do not discurage these types of discussions as we can all learn more about our animals and how to BEST care for them based off of some debates and make our own decisions. Like the substrate vs no substrate.
 
Don't get me wrong, I love this type of debate when appropriate. But this type of post usually means someone is fishing for a compliment. If you need someone to tell you how smart you are then your really not that smart. Smart people don't need others to tell them how smart they are, they know already.

I find the Amazonian stingrays to be amazing creatures, and I find that learning about the fish that I keep is a worthwhile endeavor. Sharing a passion for fish seems to be the point of this forum. Science and knowledge also seem to be a point of this forum. Perhaps I should change the topic to better meet your expectations. From now on, I would prefer that we discuss which flake food would be better for my goldfish.

Also, when you refer to the state of another person, use either the contraction "you're" or "you are". Otherwise, you're really not that smart. You can take your insinuation and shove it up your ass.

Science is best left to the people doing the experiments. Our men and women in lab coats and in the field are the people to whom we should consult for the answers. Lay people should defer to scientists. This is exactly the idea for which I advocate.

The post is meant to share the amazement I have with how these fish came to exist in the Amazon in the first place. I doubt that anyone who has ever studied the subject scientifically would comment. I am simply sharing their ideas. I find that it is worth doing so because these ideas inspire discussion. I have no idea and am not qualified to answer which route evolution did take, but I think that both hypotheses are interesting and noteworthy.
