WConolophus marthae, the Galápagos pink land iguana, is a species of lizard of the family Iguanidae. This critically endangered iguana is native only to the Wolf Volcano in northern Isabela Island of the Galápagos (Ecuador). It has a pink body with some dark stripes, prompting some to call it the pink iguana or the Galápagos rosy iguana. The species was first discovered in 1986 and was identified as a separate species, distinct from the Galápagos land iguana, early in 2009. This species is the only example of ancient diversification in the genus Conolophus and is one of the oldest events of divergence ever recorded in the Galápagos.

WThe 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. 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 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.
WMegaoryzomys curioi, also known as the Galápagos giant rat, is an extinct species of sigmodontine rodent, known only from Santa Cruz Island in the Galápagos Islands. It likely met its demise when European settlers introduced invasive species to the island. It is the only species in the genus Megaoryzomys. Its relationships are currently unclear; it has been placed in both Oryzomyini and Thomasomyini in the past.
WMicrolophus albemarlensis, the Galápagos lava lizard, also known as the Albemarle lava lizard, is a species of lava lizard. It is endemic to the Galápagos Islands, where it occurs on several islands in the western archipelago: the large islands Isabela, Santa Cruz, Fernandina, Santiago and Santa Fe, as well as several smaller islands: Seymour, Baltra, Plaza Sur, Daphne Major and Rábida. It is the most widespread of the Galápagos species of Microlophus, the others only occurring on single islands. Some authors however, consider populations on Santiago, Santa Cruz, and Santa Fe to be distinct species. The species is commonly attributed to the genus Microlophus but has been historically placed in the genus Tropidurus.

WThe Galápagos racer is a colubrid snake in the genus Pseudalsophis that is endemic to the Galápagos Islands. It is a mildly venomous constrictor and is considered not aggressive and harmless to humans. The two subspecies are the eastern and western racers, the latter being larger, longer, and darker than the former. The western subspecies specializes in hunting fish, while both subspecies eat small reptiles, eggs, rodents, and bird hatchlings. The Galapagos racer is near threatened due to recently introduced species that feed on snake eggs, including pigs, rats, mice, and cats. It is one of only three species of snakes on the Galápagos Islands, and it was first described in 1860. In November 2016, a video clip from the BBC series Planet Earth II showing a group of Galápagos racers hunting marine iguana hatchlings became a viral trend.

WThe Volcán Wolf giant tortoise, also known as the Wolf Volcán giant tortoise, is a species of Galápagos tortoise native to the north side of Ecuador's Isabela Island. It is most commonly found on the northern, western, and southwestern slopes of Volcán Wolf, the volcano that it is named for. Having evolved to live in a specific environment, C. becki only occupies an estimated range of about 263 square kilometers. An estimated 1,150 Volcán Wolf giant tortoises inhabit Volcán Wolf.
WThe western Santa Cruz tortoise is a species of Galápagos tortoise endemic to Santa Cruz Island in the Galápagos. They are found only on the southwestern slopes of the island, with an estimated range of 141 sq. kilometers. There are approximately 3400 individuals in the wild, and have seen rising numbers in population, despite being critically endangered. MtDNA evidence shows that there are actually three genetically distinct populations on Santa Cruz Island. They are characterised by a black, oval carapace that is domed, higher in the centre than in the front, and broad anteriorly.
WXylocopa darwini, the Galápagos carpenter bee, is one of only three species of bees found in the Galápagos Islands, to which it is endemic. This species is sexually dimorphic, is found on 75% of the largest islands, and is known for its complex behavior. As the only native bee, Xylocopa darwini serves as an important primary pollinator within the plant-pollinator network of the archipelago.
