Answer: d) none

Olive ridley sea turtle

Olive ridley sea turtle

  • Also known as the Pacific ridley sea turtle.
  • Distribution: found in warm and tropical waters, primarily in the Pacific and Indian Oceans.
  • Olive ridley turtles are best known for their behaviour of synchronized nesting in mass numbers.
  • In the Indian Ocean, the majority of olive ridleys nest near Gahirmatha in Odisha.
  • The coast of Odisha in India is the largest mass nesting site for the olive ridleys.

What’s the difference between turtles and tortoises?



  • Lives in water
  • Lives on land
  • Come to land to lay eggs
  • Everything happens on land
  • Good swimmers
  • Bad swimmers
  • Carnivores (flesh eating)
  • Herbivores (plant eating)
Terrapins are almost a combination of turtles and tortoises. They live in water, mostly small dams or ponds; however they can also live on land.

‘Near Threatened’ Reptiles

Sispara day gecko (Cnemaspis sisparensis)

Sispara day gecko

  • Distribution: Endemic to Western Ghats, and found in Sispara, Nilgiris, Kavalai near Cochin.
  • Threats: Habitat conversion and modification.

‘Critically Endangered’ Fish

The Pondicherry Shark (Carcharhinus hemiodon)

Pondicherry Shark

  • Distribution: Indian Ocean – from Gulf of Oman to Pakistan, India and Sri Lanka.
  • In scattered localities spanning India to New Guinea. Also been recorded at the mouth of the Hooghly river.
  • Threats: Large, expanding, and unregulated commercial fisheries in inshore localities and habitats.

The Ganges Shark (Glyphis gangeticus)

Ganges Shark

  • It occurs in the turbid waters of the Ganga river and the Bay of Bengal.
  • The small eyes suggest that it is adapted to living in turbid water (just like dugong), while the slender teeth of the species suggest that it is primarily a fish-eater.
  • Distribution: It occurs in India and possibly in Pakistan. The Ganga river system and Hooghly river mouth are its known habitats.
  • Threats: Major fisheries targeting sharks. Other probable threats include overfishing, pollution, increasing river use and construction of dams and barrages.

Large-tooth Sawfish (Pristis microdon)

Large-tooth Sawfish

  • Distribution: Western part of the Indo-Pacific (East Africa to New Guinea, Philippines and Vietnam to Australia).
  • In India, it is known to enter the Mahanadi river, up to 64 km inland, and also is very common in the estuaries of the Ganga and Brahmaputra.
  • Threats: The principal threat to all sawfish are fisheries. Their long tooth-studded saw makes them extraordinarily vulnerable to entanglement in any sort of net gear.
  • When sawfish are caught in by catch, they often end up being traded because of the very high value of their products (meat is high quality and fins and saws extremely valuable in international trade).
  • Major habitat changes include construction of dams over rivers, siltation, pollution from industries and mining operations.

Long-comb Sawfish or Narrow-snout Sawfish (Pristis zijsron)

Long-comb Sawfish or Narrow-snout Sawfish

  • This species was reported as frequently found in shallow water. It inhabits muddy bottoms and also enters estuaries.
  • Distribution: Indo-Pacific region including Australia, Cambodia, China, India, Indonesia and Malaysia.
  • Threats: This species has been damaged intensively, both as a target species and as incidental by catch in commercial, sport or shark-control net fisheries, as well as for aquarium display. As a result, it has become severely depleted in recent decades, and now appears to have been extirpated from many parts of its range.

‘Endangered’ Fishes

Knife-tooth Sawfish (Anoxypristis cuspidata)

Knife-tooth Sawfish

  • Distribution: Widespread in western part of the Indo-Pacific region, including Red Sea.
  • Threats: Similar to Long-comb Sawfish.

  • Distribution: Endemic to India. Spread along the coastal savannah, tropical lowland rain forests and montane forests up to an altitude of 2000 m above mean sea level.
  • Threats: Major threats causing the disappearance of this species is habitat alteration and degradation.

Gooty Tarantula, Metallic Tarantula or Peacock Tarantula (Poecilotheria metallica)

Gooty Tarantula, Metallic Tarantula or Peacock Tarantula

  • It was first found in Gooty (Ooty/Udagamandalam).

  1. 1, 2 and 3 only
  2. 1, 3 and 4 only
  3. 2 and 4 only
