tadpole शब्द के हिंदी अर्थ का उदाहरण:

জজজ इनमें अधिकांश अपनी बेंगची (tadpole) अवस्था में गलफड़ों द्वारा ओर वयस्क अवस्था में फुफ्फुसों द्वारा श्वसन करते हैं, किंतु कुछ जीवन पर्यंत गलफड़ों द्वारा ही श्वसन करते हैं।

tadpole's Usage Examples:

The tadpole of the North American bull-frog measures six inches, and that of the Chilian Calyptocephalus gayi seven and a half inches.

If in the course of the first twenty-four hours this larva meet with a tadpole it attaches itself at once and undergoes further development.

In the former case the larva creeps along the tadpole until it reaches the branchial opening into which it darts, fixes its sucker, and then throws off its cilia.

A tadpole is the larva of a tailless Batrachian after the loss of the external gills and before the egress of the fore limbs (except in the aberrant Xenopus) and the resorption of the tail.

The hind limbs appear as buds at the base of the tail, and gradually attain their full development during the tadpole life.

tadpole stage.

Erasmus Darwin, the grandfather of Charles Darwin, set forth ',in' Zoonomia a much more definite theory of the relation of variation to evolution, and the following passage, cited by Clodd, clearly expresses it: "When we revolve in our minds the metamorphoses of animals, as from the tadpole to the frog; secondly, the changes produced by artificial cultivation, as in the breeds of horses, dogs and sheep; thirdly, the changes produced by conditions of climate and season, as in the sheep of warm climates being covered with hair instead of wool, and the hares and partridges of northern climates becoming white in winter; when, further, we observe the changes of structure produced by habit, as shewn especially by men of different occupations; or the changes produced by artificial mutilation and prenatal influences, as in the crossing of species and production of monsters; fourth, when we observe the essential unity of plan in all warmblooded animals - we are led to conclude that they have been alike produced from a single living filament."

It is absurd to call the larva of a newt or of a Caecilian a tadpole, nor is the free-swimming embryo of a frog as it leaves the egg a tadpole.

In accordance with this view there would be also some probability in favour of regarding the collar nerve-tube of the Enteropneusta as the equivalent of the cerebral vesicle only of Amphioxus and the Ascidian tadpole, and also of the primary forebrain of vertebrates.

TADPOLE, a term often, but wrongly, applied indiscriminately to all Batrachian larvae.
