India Stamps Issue On Aldabra Giant Tortoise



















The Aldabra Giant Tortoise (Geochelone gigantea), from the islands of the Aldabra Atoll in the Seychelles, is one of the largest tortoises in the world. This species is widely referred to as Geochelone gigantea

The carapace is a dark blue or black color with a high domed shape. It has stocky, heavily scaled legs to support its heavy body. The neck of the Aldabra Giant Tortoise is very long, even for its great size, which helps the animal to exploit tree branches up to a meter from the ground as a food source.

Similar in size to the famous Galapagos Giant Tortoise, its carapace averages 120 cm (47 inches) in length. The average weight of a male is around 250 kg (551 pounds), but one male at the Fort Worth Zoological Park weighs over 360 kg (793 pounds). Females are generally smaller than males, with average specimens measuring 90 cm (35 inches) in length and weighing 150 kg (330 pounds).

The main population of the Aldabra Giant Tortoise resides on the islands of the Aldabra Atoll in the Seychelles. The atoll has been protected from human influence and is home to some 152,000 giant tortoises, the world's largest population of the animal. Another isolated population of the species resides on the island of Zanzibar. The tortoises exploit many different kinds of habitat including grasslands, low scrub, mangrove swamps, and coastal dunes.







Large tortoises are among the longest-lived animals on the planet. Some individual Aldabra Giant Tortoises are thought to be over 100 years of age, but this is difficult to verify because they tend to outlive their human observers. Adwaitya (The One and Only) was reputedly one of four brought by British seamen from the Seychelles Islands as gifts to Robert Clive of the British East India Company in the 18th century and came to Kolkata Zoo in 1875. At its death in March 2006 at the Kolkata (formerly Calcutta) Zoo in India, Adwaitya is reputed to have reached the longest ever measured life-span of 255 years (birth year 1750), although the accuracy of this is disputed due to a lack of contemporary records. Today, Esmeralda is thought to be the oldest living Giant Tortoise at 170 years old, since the death of Harriet at 176, a Galapagos giant tortoise. Esmeralda is an Aldabra Giant Tortoise.
