The twenty-two species of Galapagos reptiles belong to five families: tortoises, marine turtles, lizards/iguanas, geckos and snakes. Twenty are endemic to the archipelago and many are endemic to individual islands.

The Islands are well-known for their giant tortoises ever since their discovery and play an important role in the development of Charles Darwin's theory of evolution. The name "Galapagos" originates from the Spanish word “galapago” meaning “saddle.”

REPTILE SPECIES IN THE GALAPAGOS

SEA BIRD SPECIES IN THE GALAPAGOS

The Galapagos archipelago is surrounded by thousands of miles of open ocean which provide seabirds with a prominent place in the fauna of the Islands. There are 19 resident species (5 are endemic), most of which are seen by visitors. There may be as many as 750,000 seabirds in Galapagos, including 30% of the world's blue footed boobies, the world's largest red footed booby colony and the largest concentration of masked boobies in the world (Harris, 1984).

MAMMAL SPECIES IN GALAPAGOS

Oceanic Islands are typically lacking in mammals and the Galapagos are no exception. Only six species of mammals are native to the Islands. The absence of large predators probably accounts for the fearlessness of the other native species towards humans. Most mammals arrived on either rafts, vegetation or by swimming.

Whales (7 species)
Dolphins (3 species)

PLANTLIFE IN THE GALAPAGOS

The Islands lie in the Pacific Dry Belt, so most of the archipelago's land area is covered by semi-desert or desert vegetation. Only the higher parts of the larger Islands receive enough rain to be considered tropical and lush. There are roughly 600 native taxa (species, subspecies and varieties) of vascular plants (42% are endemic) and some 190 species introduced by humans. It is easier to identify most plant species and also makes it easier to understand evolutionary relationships because the flora is so species poor. Here we list the more common and better known plant species, grouped together according to ecological zones.

MARINE LIFE IN GALAPAGOS

A snorkeling or diving opportunity in Galapagos should not be missed. Here you'll find a bizarre mixture of cold and warm water species. The main concentration of fish species occurs between the surface and 60 feet! Snorkelers should be good swimmers and know basic snorkeling techniques. Divers must be experienced and frequent divers. Some sites may have strong currents. Water temperatures will be cooler July to November when a wet suit would be practical. Sharks are common in Galapagos, however, there is no record of a shark attack on a human being in Galapagos waters.

Almost 300 species of fish have been identified in Galapagos. This is by no means a comprehensive list. You will find the most commonly seen species in abundance and of ecological importance. Most of Galapagos fish species (54%) have their closes affinity from the Panamic province. Fishes from the Indo-west Pacific area amount to about 12%, 7% from Peru-Chile province, 5% from the East Pacific offshore Islands and 23% are endemic to Galapagos.

INTERTIDAL MARINE LIFE

Echinoderms - Sea Urchins, sea star, sea cucumbers, sand dollars
Crustaceans - barnacles, crabs (Sally lightfoot), lobsters, shrimp
Molluscs - snails, chitons, shellfish, squid and octopus
