Toads

Toads are differentiated from frogs by the presence of parotoid glands, which take the shape of lumps at the back of their heads. Their skin also tends to take a warty appearance and coupled with a larger size, classify them loosely from frogs. Nevertheless, the distinctions are sometimes unclear. Some species tend to be terrestial while others burrow. Toads are also able to secrete a toxin through their parotoid glands when stressed. Is is not true that all toads are large, as some Malaysian species are no bigger than a thumb. Also, large toads tend to be less active in movement while smaller species with long hind legs can be agile jumpers.
