Hylarana Temporalis - Growth and Development

Growth and Development

The tadpoles of bronzed frogs start appearing in the streams by October till March. They are at least 11–14 mm long at metamorphosis and weigh about 100–170 mg. The larval duration varies from 90–120 days. The dorsal side of the tadpoles bear a muddy green/white/yellowish or olive brown colour while their lateral side is usually muddy. They carry a triangular snout with a single, sinistral and lateral spiracle. Tail fin is transparent and pointed with moderately developed musculature. Slight pigmentation is visible on the skin of tail muscles and tail fins. The height of the dorsal fin is greater than the ventral fin. The teeth are blunt with the dental formula 2(2)/3(1). A characteristic yellowish brown strip is formed on the dorsal side between the snout and the posterior tip. On the lateral side, a black strip runs from the anterior to the posterior side of the body. Within a week of metamorphosis, small bronzed coloured strips appear on either sides of the lower jaw, between the snout and the posterior point of the forelimbs. The bronzed strips are interrupted below the forelimbs.

Famous quotes containing the words growth and, growth and/or development:

    Cities force growth and make men talkative and entertaining, but they make them artificial. What possesses interest for us is the natural of each, his constitutional excellence. This is forever a surprise, engaging and lovely; we cannot be satiated with knowing it, and about it; and it is this which the conversation with Nature cherishes and guards.
    Ralph Waldo Emerson (1803–1882)

    Interpretation is the evidence of growth and knowledge, the latter through sorrow— that great teacher.
    Eleonora Duse (1858–1924)

    The Cairo conference ... is about a complicated web of education and employment, consumption and poverty, development and health care. It is also about whether governments will follow where women have so clearly led them, toward safe, simple and reliable choices in family planning. While Cairo crackles with conflict, in the homes of the world the orthodoxies have been duly heard, and roundly ignored.
    Anna Quindlen (b. 1952)
