Thanks to DNA testing, a new species of bottlenose dolphin has been discovered in the waters off southern Australia. It is only the second new dolphin to be discovered in 50 years. I always thought examining a moth's genitalia to tell which species it was seemed a bit far to go but when you have to check it's DNA that seems a bit like cheating to an old-fashioned guy like me. As yet the species has not been named.
