A new giant tortoise
species has been identified on the Galapagos Islands, making 11 existing
species in total. It is now believed that 15 species of giant tortoise lived on
Galapagos Islands, with four species extinct, leaving 11 remaining. Galapagos
Islands – Insulae de los Galopegos –
means Islands of the Tortoises.
A team of Ecuadoran
scientists identified the new giant tortoise species after genetic testing (The Telegraph, October 22, 2015). It was
originally thought that the two giant tortoise populations on the Santa Cruz
island of the Galapagos Islands were the same species, but after testing, two
separate species were identified.
The population of
giant tortoises living on the eastern side of Santa Cruz island is a different
species, said research leader Gisella Caccone from Yale University. The
researchers have called the new species Chelonoidis
donfaustoi – distinct from the other species, Chelonoidis nigra. The
new species was named in honour of
Fausto Llerena who looked after the famous Lonesome George, the last known
survivor of his species. Lonesome George was a male giant tortoise from the
Pinta island of the Galapagos Islands, who died in June 2012.
Ecuadoran scientist,
Washington Tapia, said there are about 250-300 of the new species of giant
tortoise. Research commenced in 2002 when two scientists noticed a difference
in the formation of the shells of both populations of giant tortoises. They
took genetic samples and in 2005 the preliminary results suggested that the
eastern tortoises were a different species. It has now been confirmed.
The head of the
Galapagos National Park, Alejandra Ordonez, said that research is ongoing to
determine the exact distribution of the new species and their nesting areas. The
Galapagos archipelago of volcanic islands is 1,000 kilometres (620 miles) west
of Ecuador in the Pacific Ocean. In 1979 the Natural Reserve became UNESCO’s
first World Heritage Site.
