Colombo's zoo has a fine collection of animals, birds, reptiles and fish from all over the world, but in particular showcases the fauna of the island. The complex includes an aquarium, which is the only one of its kind in Asia displaying more than 500 varieties of aquatic life. There is also a walk-through aviary, reptile enclosure and butterfly park. One of the most popular attractions at the zoo are the daily elephant shows, which take place at 5.15pm.
