Care for Nature on Singapore stamps .



Singapore Post issued the stamps depicted 4 speciesi.e: Copper cheeked frog, Green crested lizard, Green Turtle and Water monitor which have to be concern as part of the environment care.

Green turtles are the largest of all the hard-shelled sea turtles with a comparatively small head. Adult green turtles are unique among sea turtles in that they are herbivorous, feeding primarily on seagrasses and algae. This diet is thought to give them greenish coloured fat. A green turtle's carapace (top shell) is smooth and can be shades of black, gray, green, brown, and yellow. Their plastron (bottom shell) is yellowish white. The green turtle is globally distributed and generally found in tropical and subtropical waters along continental coasts and islands between 30° North and 30° South. Green turtles are protected by various international treaties and agreements as well as national laws. Green turtles are listed in Appendix I of the Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES), which means that international trade of this species is prohibited.





Green Crested Lizard or named Bronchocela cristatella is an agamid lizard found in Southeast Asia: Malaysia, Singapore, Indonesia, Philippines, South Thailand, South Myanmar and India (Nicobar Islands). It is found in forests as well as parks and rural areas. In Singapore its range is declining, as it is in competition with the introduced Calotes versicolor (Changeable Lizard). The males have a crest on the neck and a very long thinly tail (75% of total length). The body length is around 13 cm, and the total length is around 57 cm. They have special distinctive characters like a dark ring around the eye and a dark spot at the back of the head. Also they can change body colour from a bright green to darker brown when threatened.

Copper cheeked frog is a highly common species that can be found in secondary to primary rainforest, from lowland to upper-level rainforest. This species can easily be identified by its distinct dark brown tympanum. It has relatively long toes, which end in rounded tips. The species is best identified by its white lips and brownish tympanum (external ear-drum). The Copper cheeked frog is nocturnal and be found perched on the vegetation and rocks along streams. Copper cheeked frog ranges from Southern Thailand, throughout Malaysia and forested parts of Singapore, to the islands of Borneo, Sumatra, Java, Bali and Sulawesi.

Water monitor or named Varanus salvator is a large species of monitor lizard. Water monitors are one of the most common monitor lizards found throughout Asia, and range from Sri Lanka, India, Indochina, the Malay Peninsula and various islands of Indonesia, living in areas close to water. Water Monitors are carnivores, and have a wide range of foods. They are known to eat fish, frogs, rodents, birds, crabs, and snakes. They have also been known to eat turtles, as well as young crocodiles and crocodile eggs. Water monitors can be defensive, using their tail, claws, and jaws when fighting. They are excellent swimmers, using the raised fin located on their tails to steer through water.
