Anura Sea Creature

The name, Anura, meaning "without tail," identifies one of these: with one exception (Ascaphus), adult frogs do not have tails. Anurans represent, by far, the most speciose, diverse, and widespread of the three extant amphibian orders. They are found throughout most of the world, except in polar regions, and some oceanic islands and extremely xeric deserts. Anuran diversity is greatest in the tropics. Twenty-five families are currently recognized, representing more than 4,000 species, with more being discovered regularly. This clade is also referred to as Batrachia and is placed in superorder Salientia.
