The Merlion is THE symbol of Singapore. The Singa-Laut (in Malay) is the singaporean equivalent of the Eiffel Tower for Paris (or Las Vegas). If you visit the small country, you will definitely have your picture taken in front of it, and a bunch a souvenir with this creature with the head of a lion and the body of a fish.
Used as a trademarked symbol of the State-City since 1966 (3 years after its independence from the United Kingdom), the Merlion is so popular that 5 of them are present throughout the Southeast Asian island city-state. The most famous ones are, first in the Merlion Park, near the Singapore CBD, both the original statue/fountain and a two-metre-tall cub statue standing behind it (as the picture shows), and then in Sentosa Island, a 37 metre-tall replica, that tourists can actually climb into.
