Dolphins are our mammal cousins that got tired of the land and evolved back into the sea. They’re generally pretty cool and/or cheeky and quite intelligent. Hence it is appalling to hear that around 50 dolphins were massacred in the Kalpitiya area, apparently with dynamite. In the video above you can see dolphins in Brazil actually helping fishermen by herding fish and communicating. Around Kalpitiya dolphins are quite happy to swim with passing boats because they’re not scared of us. And they shouldn’t be. What a terrible and senseless thing.
