The Antiguan racer is a slender, light-brown snake that grows to about a metre long. It is completely harmless to people — it only eats small lizards and frogs. The name 'racer' comes from the way it moves quickly through the leaf litter on the forest floor when it feels surprised.
The main reason this snake became so rare is that rats were accidentally brought to the islands on ships long ago. Rats eat snake eggs, and because the Antiguan racer lays its eggs on the ground, the nests were very easy for rats to find and destroy. Conservation teams worked very hard to remove rats from Great Bird Island, and the snake population began to recover almost immediately.
Scientists count the snakes every year by carefully catching and releasing them. Each snake gets a tiny mark so it can be recognised next time. When the count showed the numbers growing, it was a big celebration — proof that conservation really works when people try hard enough.
The Antiguan racer is a symbol of hope for wildlife across the Caribbean. Schools on Antigua learn about it, and children help by taking part in beach clean-ups that protect the snake's coastal habitat. Being so rare makes each individual snake incredibly important.
