Short-Beaked Echidna, Tasmania, AustraliaIt’s a little messy down there in the undergrowth, but that’s the way echidnas like it. These Australia natives seem to always have that snout in the ground routing around for ants. Echidnas are monotremes, one of the three groups of living mammals — the other two being marsupials and placentals. Platypus are also monotremes and like the echidna they do something that no other mammal does — they lay eggs. I photographed this one in northern Tasmania while on a hike. Nikon D810 with Nikkor 200-400mm lens (at 400mm) ISO 800, f/4 at 1/200th of a second.
