A team of scientists has discovered 123 new varieties of animals, insects and plants on the South East Asian Island since 2007, after a pact was signed to ensure the safety of the Iceland.

The discovery includes that of color-changing frogs, world's longest stick insect as well as a slug shooting "love darts".

The list of the discovered species has been released this Thursday by the World Wildlife Fund (WWF) in order to spot Earth Day. The move has been carried out by WWF with the aim of generating awareness on the importance of protecting the areas having dense biodiversity.

Director of the campaigns at WWF, David Norman shared that there are a number of interesting facts associated with the smaller species found.

"About half of all synthetic drugs have a natural origin -- these are commercial drugs based on plants and sometimes animals. So we can't afford to lose species", he said.

The total number of new varieties of plants found in Borneo over the last three years is greater than the total of all the remaining categories combined. In total, 67 new plant species have been discovered in addition to the 29 invertebrates, 17 new varieties of fish, one bird, five amphibians and five reptiles.
