Tadpole

Description:

Tadpoles are young amphibians that usually live in the water, though some tadpoles may be terrestrial.[1] During the tadpole stage of the amphibian life cycle, most respire by means of autonomous external or internal gills. They do not usually have arms or legs until the transition to adulthood, and typically have dorsal or fin-like appendages and a tail with which they swim by lateral undulation, similar to most fish. As a tadpole matures, it most commonly metamorphosizes by gradually growing limbs (usually the legs first, followed by the arms) and then (most commonly in the case of frogs) outwardly absorbing its tail by apoptosis. Lungs develop around the time of leg development, and tadpoles late in development will often be found near the surface of the water, where they breathe air. During the final stages of external metamorphosis, the tadpole's mouth changes from a small, enclosed mouth at the front of the head to a large mouth the same width as the head. The intestines shorten to make way for the new diet. Most tadpoles are herbivorous, subsisting on algae and plants. Some species are omnivorous, eating detritus and, when available, smaller tadpoles.

Habitat:

Tadpoles live in lakes, ponds, creeks, streams and small water pools that have developed due to rainfall, residing in nutrient-rich, murky brown or greenish-colored water.

Notes:

I found this tadpole at school.It located in the pound at the garden near the canteen.It looked dark and small body with less mass.From my reserch I found that this tadpole will grow to be Common Bush Frog
