Delft Island is the only island in Sri Lanka where wild horses can be seen. The reason for this is that it was an island where horses were brought to the country by the colonial people for various purposes and later allowed to go wild. That is, not taking proper care of it. Later, the animals became extinct and became dwarfed due to lack of proper nutrition. (Some say horses are also part of a mixed animal). Delft Island is located in the Palk Strait of the Indian Ocean.
