Tiliqua scincoides
When a blue-tongued skink is threatened, it puffs up its body, hisses, and flashes a wide, cobalt-blue tongue in a startle display that works on predators and surprised gardeners alike. Big, slow, and broad-headed, it hauls itself through leaf litter eating snails, beetles, and fallen fruit, and it gives birth to live young rather than laying eggs — up to a dozen fully-formed babies at a time.
