The echidna is a carnivore which lives on a diet of insects. The egg is incubated for another 10 days before the tiny offspring hatches with the aid of an egg tooth and fleshy bulb (caruncle)—structural holdovers from the creature’s reptilian ancestry. Their long, cylindrical snouts can detect the small electrical currents put out by their prey. The Animal Diversity Web team is excited to announce ADW Pocket Guides!
