Pseudalsophis occidentalis otherwise known as the Western Galapagos racer, is a species of snake of the family Colubridae.
The snake is found on Fernandina Island and Isabela Island in the Galápagos Islands,. [2]
The Galápagos Islands are an archipelago of volcanic islands in the Eastern Pacific, located around the Equator 900 km (560 mi) west of South America. They form the Galápagos Province of the Republic of Ecuador, with a Spanish-speaking 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 Leptotyphlopidae are a family of snakes found in North America, South America, Africa and Asia. All are fossorial and adapted to burrowing, feeding on ants and termites. Two subfamilies are recognized.
The Galápagos hawk is a large hawk endemic to most of the Galápagos Islands.
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.
Franz Steindachner was an Austrian zoologist, ichthyologist, and herpetologist. He published over 200 papers on fishes and over 50 papers on reptiles and amphibians. Steindachner described hundreds of new species of fish and dozens of new amphibians and reptiles. At least seven species of reptile have been named after him.
The Galápagos Islands are located off the west coast of South America straddling the equator. The Galápagos are located at the confluence of several currents including the cold Humboldt Current traveling north from South America and the Panama Current traveling south from Central America make the islands cooler and provide the perfect environment for the unique mix of wildlife that inhabits the islands.
Alsophis is a genus of snakes in the subfamily Dipsadinae of the family Colubridae. Species in the genus Alsophis are among those snakes commonly called "racers". Alsophis species are endemic to the Lesser Antilles in the Caribbean. One species in the genus Alsophis, A. antiguae, is one of the world's rarest known snakes. Snakes of the genus Alsophis are small and rear-fanged, and they are considered harmless to humans. This genus contains nine described species which are recognized as being valid. Several species once included in this genus have been placed in the genera Borikenophis and Pseudalsophis.
The Galápagos penguin is a penguin endemic to the Galápagos Islands, Ecuador. It is the only penguin found north of the equator. Most inhabit Fernandina Island and the west coast of Isabela Island. The cool waters of the Humboldt and Cromwell Currents allow it to survive despite the tropical latitude. The Galápagos penguin is one of the banded penguins, the other species of which live mostly on the coasts of Africa and mainland South America. It is one of the smallest species of penguin in the world. Because of their warm environment, Galápagos penguins have developed techniques to stay cool. The feathers on their back, flippers, and head are black, and they have a white belly and a stripe looping from their eyes down to their neck and chin. Each penguin keeps only one mate, and breeds year-round. Their nests are typically in caves and crevices as protection against predators and the harsh environment. The Galápagos penguin has a lifespan of about 15 to 20 years, but due to predation, life expectancy in the wild could be significantly reduced.
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
Pseudalsophis is a genus of snakes in the family Colubridae. The genus is endemic to South America. Out of the ten species, nine are endemic to the Galapagos Islands.
The Galapagos snake eel is an eel in the family Ophichthidae. It was described by David Starr Jordan and Charles Harvey Bollman in 1890. It is a marine, tropical eel which is known from the eastern central and southeastern Pacific Ocean, including Colombia, the Gulf of California, Costa Rica, and the Galapagos Islands in Ecuador. It dwells at a depth range of 3 to 30 metres, and inhabits reefs, preferring to live in areas bearing a mixture of boulders, gravel and sand. Males can reach a maximum total length of 71 centimetres (28 in).
Joseph Richard Slevin was an American herpetologist and the second curator of herpetology at the California Academy of Sciences, with which he was affiliated for over 50 years. He collected reptile and amphibian specimens from around the world, notably in the Galápagos Islands in a 17-month expedition, and was largely responsible for re-growing the academy's herpetological collection following its destruction in the 1906 San Francisco earthquake. He wrote or co-wrote nearly 60 scientific papers, and is commemorated in the scientific names of over a dozen species or subspecies of animals and plants.
The Galápagos racer is a colubrid snake in the genus Pseudalsophis that is endemic to the Galápagos Islands. It is a mildly venomous constrictor but it is not considered aggressive or harmful 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.
Pseudalsophis thomasi, or Thomas' racer, a species of snake in the family Colubridae. It is endemic to several islands in the Galápagos group.
Scolopendra galapagoensis, also known as the Galápagos centipede and Darwin's goliath centipede, is species of very large centipede in the family Scolopendridae. It is the only representative of the genus Scolopendra on the Galapagos Islands, among twelve other species of centipede present on the Islands. It is also found on mainland South America in Ecuador and Peru, and on Cocos Island in Costa Rica.
Pseudalsophis darwini, otherwise known as Darwin's racer, is a species of snake of the family Colubridae.
Pseudalsophis hephaestus, otherwise known as the Santiago racer, is a species of snake of the family Colubridae.
Pseudalsophis hoodensis, otherwise known as the Espanola racer, is a species of snake of the family Colubridae.
