The Galápagos Islands are an archipelago of volcanic islands in the Eastern Pacific, located around the Equator 900 km (560 mi) west of the mainland of South America. They form the Galápagos Province of the Republic of Ecuador, with a population of slightly over 33,000 (2020). The province is divided into the cantons of San Cristóbal, Santa Cruz, and Isabela, the three most populated islands in the chain. The Galápagos are famous for their large number of endemic species, which were studied by Charles Darwin in the 1830s and inspired his theory of evolution by means of natural selection. All of these islands are protected as part of Ecuador's Galápagos National Park and Marine Reserve.
The Galápagos fur seal is one of eight seals in the genus Arctocephalus. It is the smallest of all eared seals. It is endemic to the Galápagos Islands in the eastern Pacific. The total estimated population as of 1970 was said to be about 30,000, although the population has been said to be on the decline since the 1980s due to environmental factors such as pollution, disease, invasive species, and their limited territory. Due to the population having been historically vulnerable to hunting, the Galápagos fur seal has been protected by the Ecuadorian government since 1934
The Galápagos Islands xeric scrub, also known as the Galápagos Islands scrubland mosaic, is a terrestrial deserts and xeric shrublands ecoregion that covers the Galápagos Islands. The Galápagos Islands are volcanic in origin, and remote from continents and other islands. The ecoregion is well known for its unique endemic species, including giant tortoises, birds, and marine iguanas, which evolved in isolation to adapt to islands' environments.
The marine iguana, also known as the sea iguana, saltwater iguana, or Galápagos marine iguana, is a species of iguana found only on the Galápagos Islands (Ecuador). Unique among modern lizards, it is a marine reptile that has the ability to forage in the sea for algae, which makes up almost all of its diet. Marine iguanas are the only extant lizard that spends time in a marine environment. Large males are able to dive to find this food source, while females and smaller males feed during low tide in the intertidal zone. They mainly live in colonies on rocky shores where they bask after visiting the relatively cold water or intertidal zone, but can also be seen in marshes, mangrove swamps and beaches. Large males defend territories for a short period, but smaller males have other breeding strategies. After mating, the female digs a nest hole in the soil where she lays her eggs, leaving them to hatch on their own a few months later.
Puerto Ayora is a town in central Galápagos, Ecuador. Located on the southern shore of Santa Cruz Island, it is the seat of Santa Cruz Canton. The town is named in honor of Isidro Ayora, an Ecuadorian president. The town is sometimes mistakenly referred to as Santa Cruz. Puerto Ayora is the most populous town in the Galápagos Islands, with a population of 12,696.
San Cristóbal Island, also known as Chatham Island, is the easternmost island in the Galápagos archipelago, as well as one of the oldest geologically. It is administratively part of San Cristóbal Canton, Ecuador.
Isabela Island is the largest of the Galápagos Islands, with an area of 4,586 km2 (1,771 sq mi) and a length of 100 km (62 mi). By itself, it is larger than all the other islands in the chain combined, and it has a little under 2,000 permanent inhabitants. The island straddles the equator.
Santa Cruz Island, also known as Indefatigable Island and by other names, is the most populous and second-largest island in the Galápagos Islands, Ecuador. Situated in the middle of the group, Santa Cruz is a shield volcano with an area of 986 km2 (381 sq mi) and a maximum altitude of 864 m (2,835 ft). The seat of Santa Cruz Canton is Puerto Ayora on Santa Cruz. The island's total population is around 18,000 with those living in smaller villages chiefly working in agriculture and cattle raising.
Santa Fe Island, also known as Barrington Island, is a small island of 24 square kilometres (9.3 sq mi) which lies in the middle of the Galápagos Archipelago in Ecuador. Visitor access is by a wet landing in Barrington Bay on the northeastern side of the island.
The Galápagos Marine Reserve (GMR) lies a thousand kilometres from the Ecuadorian mainland and covers an area of around 133,000 km2 (51,000 sq mi). The Galápagos Islands and the surrounding waters represent one of the world’s most unusual ecosystems and are rich areas of biodiversity. Recently granted UNESCO World Heritage Site status, the Galápagos Marine Reserve is the largest marine reserve in a developing country and the second largest reserve in the world.
Galápagos National Park was established in 1959. It began operation in 1968, and it is Ecuador's first national park and a UNESCO World Heritage Site.
The Galápagos land iguana is a very large species of lizard in the family Iguanidae, and one of three species of the genus Conolophus. It is endemic to the Galápagos Islands off of Ecuador's Pacific coast, inhabiting the dry lowlands of Fernandina, Isabela, Santa Cruz, North Seymour, Baltra, and South Plaza islands.
The Tropical Eastern Pacific is one of the twelve marine realms that cover the coastal waters and continental shelves of the world's oceans. The Tropical Eastern Pacific extends along the Pacific Coast of the Americas, from the southern tip of the Baja California Peninsula in the north to northern Peru in the south. It is bounded on the north by the Temperate Northern Pacific realm, and on the south by the Temperate South America realm.

Typhina coronata is a species of sea snail, a marine gastropod mollusk in the family Muricidae, the murex snails or rock snails.
Tortuga Bay is located on the Santa Cruz Island, about a 20-minute water-taxi ride from the main water taxi dock in Puerto Ayora. There is also a walking path, which is 1.55 miles (2,490 m) and is open from six in the morning to six in the evening. Visitors must sign in and out at the start of the path with the Galapagos Park Service office. Tortuga Bay has a gigantic, perfectly preserved beach that is forbidden to swimmers and is preserved for the wildlife where many marine iguanas, galapagos crabs and birds are seen dotted along the volcanic rocks. There is a separate cove where you can swim where it is common to view white tip reef sharks swimming in groups and on occasion tiger sharks
