	Pseudalsophis Biserialis The Galápagos racer (''Pseudalsophis biserialis'') 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 ''Pseudalsophis thomasi'', or Thompson's racer, a species of snake in the family Colubridae. It is endemic to several islands in the Galápagos group. Etymology The genus name ''Pseudalsophis'' comes from the name of a genus of Caribbean snakes ''Alsophis'' due to their superficial similarities, combined with the Greek word ''pseudo'' meaning false. The specific name is in honor of the herpetologist Robert A. Thomas. Description Diurnal snakes, active throughout the day with the exception of hot midday hours. They can be found in rocky areas, deciduous forest, and dry grassland habitats. Foraging predators they feed on small animals such as lava lizards, geckos, and possibly invertebrates. Snakes are mildly venomous enough to endanger small prey items but not enough to harm a human. Thompson's Racers have no natural predators however they are preyed upon by introduced black rats.

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. Early life Slevin was born in San Francisco, California, and attended St. Ignatius High School. His father, Thomas E.
