The National Flag is a horizontal tricolour of deep saffron (kesaria) at the top, white in the middle and dark green at the bottom in equal proportion. The ratio of width of the flag to its length is two to three. In the centre of the white band is a navy-blue wheel which represents the chakra.The top saffron colour, indicates the strength and courage of the country. The white middle band indicates peace and truth with Dharma Chakra. The green shows the fertility, growth and auspiciousness of the land.Its design is that of the wheel which appears on the abacus of the Sarnath Lion Capital of Ashoka. Its diameter approximates to the width of the white band and it has 24 spokes. The design of the National Flag was adopted by the Constituent Assembly of India on 22 July 1947.It is really amazing to see the various changes that our National Flag went through since its first inception. It was discovered or recognised during our national struggle for freedom. The evolution of the Indian National Flag sailed through many vicissitudes to arrive at what it is today.
The state emblem is an adaptation from the Sarnath Lion Capital of Ashoka. In the original, there are four lions, standing back to back, mounted on an abacus with a frieze carrying sculptures in high relief of an elephant, a galloping horse, a bull and a lion separated by intervening wheels over a bell-shaped lotus. Carved out of a single block of polished sandstone, the Capital is crowned by the Wheel of the Law (Dharma Chakra).
In the state emblem, adopted by the Government of India on 26 January 1950, only three lions are visible, the fourth being hidden from view. The wheel appears in relief in the centre of the abacus with a bull on right and a horse on left and the outlines of other wheels on extreme right and left. The bell-shaped lotus has been omitted. The words Satyameva Jayate from Mundaka Upanishad, meaning \’Truth Alone Triumphs\’, are inscribed below the abacus in Devanagari script.
The Indian peacock, Pavo cristatus, the national bird of India, is a colourful, swan-sized bird, with a fan-shaped crest of feathers, a white patch under the eye and a long, slender neck. The male of the species is more colourful than the female, with a glistening blue breast and neck and a spectacular bronze-green tail of around 200 elongated feathers. The female is brownish, slightly smaller than the male and lacks the tail. The elaborate courtship dance of the male, fanning out the tail and preening its feathers is a gorgeous sight.
Lotus (Nelumbo Nucipera Gaertn) is the National Flower of India. It is a sacred flower and occupies a unique position in the art and mythology of ancient India and has been an auspicious symbol of Indian culture since time immemorial.
India is rich in flora. Currently available data place India in the tenth position in the world and fourth in Asia in plant diversity. From about 70 per cent geographical area surveyed so far, 47,000 species of plants have been described by the Botanical Survey of India (BSI).
National Aquatic Animal
River Dolphin is the National Aquatic Animal of India. This mammal is also said to represent the purity of the holy Ganga as it can only survive in pure and fresh water. Platanista gangetica has a long pointed snout and also have visible teeth in both the upper and lower jaws. Their eyes lack a lens and therefore function solely as a means of detecting the direction of light. Dolphins tend to swim with one fin trailing along the substrate while rooting around with their beak to catch shrimp and fish. Dolphins have a fairly thick body with light grey-brown skin often with a hue of pink. The fins are large and the dorsal fin is triangular and undeveloped. This mammal has a forehead that rises steeply and has very small eyes. River Dolphins are solitary creatures and females tend to be larger than males. They are locally known as susu, because of the noise it makes while breathing. This species inhabits parts of the Ganges, Meghna and Brahmaputra rivers in India, Nepal, Bhutan and Bangladesh, and the Karnaphuli River in Bangladesh.
River dolphin is a critically endangered species in India and therefore, has been included in the Schedule I for the Wildlife (Protection) Act, 1972. The main reasons for decline in population of the species are poaching and habitat degradation due to declining flow, heavy siltation, construction of barrages causing physical barrier for this migratory species.
