    What is exactly that says.. species x is different to species y?

    Sounds like a daft question.. but take for example EBJDs. They’re the same shape of fish as the “normal” JD, but they’re an entirely different colour.. in fact colour scheme. Why are they still taxonomically recognised as the same species?

    The classic way is that members of a given species can interbreed and produce fertile offspring mate but it’s a bit of a fuzzy subject and there are several schools of thought. Since starting the site I’ve read an awful lot of description papers for fish and many authors seem to define species on the basis of morphological characters which for me is where a lot of the confusion comes in. <img src="style_emoticons//rolleyes.gif” style=”vertical-align:middle” emoid=”:rolleyes:” border=”0″ alt=”rolleyes.gif” /> Bring on the DNA tests!! <img src="style_emoticons//biggrin.gif” style=”vertical-align:middle” emoid=”:D” border=”0″ alt=”biggrin.gif” />
