A five-foot long dolphin weighing more than 150 kgs washed ashore the Marina beach in Chennai. It appeared to have died from serious head injuries. The range officer who examined the body said that it could have died due to an injury from a trawler. Supraja Dharini, the founder of an NGO called Tree foundation says that this is the third such incident in Chennai in the past three months. She said that in-depth studies must be carried out to study the migration patterns of marine animals in the region and the threats they face.
