Australian freshwater crocodile with its mouth agape in response to a threat. The palatal valve at the back of the throat is clearly visible (normally used to prevent influx of water down the throat when the crocodile is underwater). The narrow jaws and sharp teeth provide indications of the diet of this species, which is biased towards fish. However, freshies take a wide variety of prey items, with the normal exception of larger mammals. With most crocodiles, numerous small prey items make up the majority of the diet.
