Common Animal species - 2

REPTILES:

India has a wide variety of lizards, snakes and turtles, with a high level of endemism. The lizards include the common garden lizard, Fan throated l i z a r d , Chamelion, Skink, Common Monitor and Water Monitor. Some of these are threatened due to trade in reptile skins. Indian snakes include the Rock Python, Russell’s viper and the Vine snake. We rarely appreciate the fact that only a few species of snakes are poisonous and most snakes are harmless. The Star tortoise and Travancore tortoise are now rare. The Olive Ridley and Flapshell turtle are the well-known turtles of India. Many turtles are becoming increasingly rare due to poaching of adults and eggs. The crocodile is our largest reptile which is poached for its prized skin. The gharial is endemic to India and is highly threatened.

Amphibia:
 Most of the amphibians found in India are frogs and toads. These include several species like the Indian Bull frog, Tree frog, etc. These amphibians are mostly found in the hotspots in the Northeast and the Western Ghats. It is now thought that global warming and increasing lev-els of UV radiation may be seriously affecting amphibian populations in some areas.

Invertebrates:
Invertebrates include a variety of taxa that inhabit both terrestrial and aquatic ecosystems. Microscopic animals like protozoa and zooplankton form the basis of the food chain in aquatic habitats. Coral is formed by colonies of polyp like animals. Worms, molluscs (snails), spiders, crabs, jellyfish, octopus are a few of the better known invertebrates found in India.There are more than a million insect species on earth that are known to science. They include grasshoppers, bugs, beetles, ants, bees, butterflies and moths. India is rich in its butterfly and moth species.

 Marine Life:
 Marine ecosystems are most frequently associated with fish and crustacea like crabs and shrimp, which we use as food. The other species that are endangered include the marine turtles, which are reptiles, and whales that are mammals. There are a large number of species of freshwater fish found in our Indian rivers and lakes that are now threatened by the introduction of fish from abroad as well as due to being introduced from one river into another. Fish are also now seriously affected by pollution. Marine fisheries are being over harvested in our coastal waters and the fish catch has decreased seriously over the last few years. Mechanized boats with giant, small-meshed nets are a major cause of depleting this resource. There are many endangered fish such as the Mahseer which once grew to over a meter in length. Many species of marine animals such as the whales, sharks and dolphins that live in the Indian Ocean are now threatened by extinction due to fishing in the deep sea.
