See it in the wild: Darwin's Racers can be seen with ~10% certainty in Punta Espinoza in Fernandina Island. 4 The specific epithet darwini honors Charles Darwin. Galápagos, Ecuador.Įtymology: The generic name Pseudalsophis, which comes from the Greek words pseudo (meaning “false”) and Alsophis (a genus of Caribbean snakes), refers to the similarity between snakes of the two genera. Although the bite of this snake is harmless, its needle-sharp teeth can cause bleeding and considerable pain.Special thanks to David Salazar-Valenzuela and Eric Osterman, our two official protectors of the Darwin's Racer, for symbolically adopting this species and helping bring the Reptiles of Galápagos project to life.ĭistribution: Pseudalsophis darwini is endemic to Isabela Island, Fernandina Island, and Tortuga Islet, which collectively account for an area of 5,313 km 2, although Darwin's Racers probably occur on a much smaller area.Black Racers never coil around their prey to suffocate them before devouring them. Although Black Racers share some characteristics common to constrictor snakes, the scientific name ‘ constrictor’ given to this species is a misnomer.The baby Black Racers have a survival rate of around forty percent, which signifies that, generally, only about eight babies get to survive through the first year of their life.The Black Racer cannot become a good pet because it can never get over its nervous disposition. These snakes have also become very uncommon in Michigan. However, the Canadian province of Ontario has given it some legal protection, because of the gradual decrease in its count. This species of snake is pretty much abundant in some places. The IUCN Red List has included this snake under the ‘least concern’ status. The creatures can live up to 10 years both in the wild, as also in captivity. The black racers can often use the same den for many years. The snakes bask outside of the den for weeks beforehand. Their hibernation mostly occurs in rock crevices or old burrows by the hillsides. These snakes hibernate in large numbers and with other species of snakes. Like most other snake species, the black racers hibernate in underground shelters during the coldest winter months (around late October), and emerge in mid-March. The baby Black Racer mostly survives by the process of camouflage. The adult snakes do not feed their babies nor protect them. During birth, the juvenile Black Racers are 6 inches long. The total number of baby black racers that can take birth at a time is a wide range varying between 3 and 32. Male Black Racers become sexually ready between the age of 1 and 2 years, whereas the female’s age of sexual maturity is between 2 and 3 years. Their breeding season extends from June to early July. The mating season of these serpents is the springtime, mostly between late April and the first half of June. Moltingīlack Racer snakes usually shed their skin once a year. This speed in locomotion has been particularly possible for their natural smooth skin and scales. Their ability to move a climb at incredible speeds comes handy since they often live in areas with human habitation, and are daytime hunters. When in danger, the snake vibrates its tail in dense grass generating a sound similar to a rattle snake’s rattles. The adults have a characteristic defense mechanism. Because these snakes dwell mostly in grassy or woody areas, they are often found in a curled position, resembling a fallen branch. Baby Black Racers camouflage themselves according to their places of habitat.
