and allah has created every animal from water of them there are some that creep on their bellies some that walk on two legs and some that walk on four. allah creates what he wills for verily allah has power over all things.
والله خلق كل دابة من ماء فمنهم من يمشي على بطنه ومنهم من يمشي على رجلين ومنهم من يمشي على أربع يخلق الله ما يشاء إن الله على كل شيء قدير
