What is Saint Lucia racer?

Saint Lucia racer is the world’s rarest species of snake, with fewer than 18 surviving in the wild found in east Caribbean island of St.Lucia. Populations of the small, non-venomous snake suffered rapid declines after mongooses were introduced from India in the late 19th Century. They were actually declared extinct in 1936 but an individual was discovered in 1973 and was very recently claimed by discovery of 11 of them in 2012.
