Aldabra giant tortoise
Large tortoises are among the longest-lived animals. Some individual Aldabra giant tortoises are thought to be over 200 years of age, but this is difficult to verify because they tend to outlive their human observers. Adwaita 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 Calcutta Zoo in 1875. At his death in March 2006 at the Kolkata (formerly Calcutta) Zoo in India, Adwaita is reputed to have reached the longest ever measured lifespan of 255 years (birth year 1750). Today, Jonathan, a Seychelles giant tortoise ("A. g. hololissa"), is thought to be the oldest living giant tortoise at the age of years and Esmeralda is second at the age of years, since the death of Harriet at 176, a Galapagos giant tortoise. Esmeralda is an Aldabra giant tortoise.
Galapagos hawk
The Galapagos hawk is similar in size to the red tailed hawk ("Buteo jamaicensis") and the Swainson's hawk ("Buteo swainsoni") of North America, but the size is variable across the islands as is recorded for many animals native to the Galapagos. They appear to be somewhat more heavily built than those well known mainland species, and going on average weights, this species is the second heaviest "Buteo" in the Americas, behind only the ferruginous hawk. The Galapagos hawk can range from in length from beak to tail with a wingspan of . The smallest hawk sizes recorded are on Marchena Island, where males average and females average . Intermediate in size are the hawks of Santiago Island, on which males weigh an average of while females average . Largest known are the hawks on Española Island, which are amongst the largest "Buteo" known anywhere, with males averaging and females averaging . The adult hawk has various colouring within the species. The adult Galapagos hawk is generally a sooty brownish black colour; the crown being slightly blacker than the back. Its feathers of the mantle are partially edged with paler brown, grey, or buff, with their white bases showing to some extent. Their tail coverts are also barred with white.The tail itself is silvery grey above, with about ten narrow black bars; below it is quite pale. The wing feathers are paler on inner webs, barred with white.
