Pictures from the underwater life in the Galápagos Islands, Ecuador: Green Sea Turtle and Galapagos Fur Seal.
Green Sea Turtle (Chelonia mydas) in the Galápagos Islands, Ecuador.
Sea turtles are reptiles whose ancestors evolved on land and returned to the sea to live about 150 million years ago. Sea turtles are excellent divers.The green turtle is a large, weighty sea turtle. Adult green sea turtles grow to 1.5 metres (5 ft) long and can weigh up to 227 kg (500 pounds).
Green sea turtles get their name from the color of their body fat, which is green from the algae or limu they eat. While juvenile green turtles eat jellyfish and other invertebrates, adult green sea turtles eat only plants.
Green sea turtle is listed as an endangered species. Its range extends throughout tropical and subtropical seas around the world, with two distinct populations: the Atlantic green turtle, normally found off the shores of Europe and North America, and the Eastern Pacific green turtle, which has been found in coastal waters from Alaska to Chile.
Galapagos Fur Seal (Arctocephalus galapagoensis) in the Galápagos Islands, Ecuador.
The Galápagos fur seal is the smallest of otariids. At maturity, males are up to 1.5 m (5 ft) long and weigh 64 kg (141 lb) on average. The Galápagos fur seal feeds primarily on fish and cephalopods.
Like Sea lions, fur seals are fin-footed mammals with amazing abilities in water. Their agility in water contrasts to their clumsy waddling on land. Some people find them difficult to distinguish from sea lions, but there are many differences that aid identification. They are smaller in overall size and the head is broader and shorter.
