Frog
Frogs and the similar toads are a large family of hundreds of species of batrachian amphibians, with a nearly worldwide distribution, absent only from high latitudes and remote oceanic islands. Even in deserts, species such as the water-holding frog, which is used as a drinking bottle by Australian aborigines, are to be found, buried deep below the ground between the infrequent rains.
Frogs in Science
Frogs have often been the subject of scientific experiment, whether in high school science class dissections or Voltaire's 1766 experiments, in which he discovered that frogs hear with their legs.[Citation Needed] The discovery that a frog's leg will kick if an electrical shock is applied to it was the scientific basis behind the reflex tests now common in doctors' offices.[Citation Needed]
Frogs in the Bible
One of the seven plagues of Egypt was of Frogs.
Leviticus declares them unclean to eat.
