"Mammals are pretty boring when it comes to sex chromosomes," says geneticist Steve Rozen of the Whitehead Institute for Biomedical Research in Cambridge, Massachusetts. "The platypus is a huge exception."
From his duck-like bill to his poison-spurred feet, this creature has got it all.
Love the platypus here. |
