Conservationists in Brazil are scrambling for answers after four or five dead dolphins have washed up on beaches every single day since mid-December. Experts are now examining the carcasses that have been learnt, and trying to deduce what is behind this sudden and grisly mass die-off.
At the time of writing, it is thought that at least 102 dead dolphins have been discovered over the past month. The lawsuit of their deaths still remains unclear, and although some have seemingly been at sea for a while, others search relatively fresh, with no obvious signeds of trauma.
“We’ve never suffered this before. It’s a tragedy, ” Leonardo Flach, chief coordinator of local NGO Boto Cinza Institute, told ABC News. “Every day we are finding four or five dolphin bodies. One daylight we will find dolphin bodies that are male and adults, and the next day, girl and puppies. But the majority of countries are scrawny and with deep scalp lesions. I’ve ever seen anything like that.”
Local conservation NGOs are worried that this might point to a bacterial or viral infection spreading through the group, but at this stage , nothing is really known. If it is something infectious, then Flach is severely worried about the future of specific populations. As dolphins are naturally social souls, the potential for it to spread is high.
There are only thought to be around 800 dolphins in the Bay of Sepetiba, which is located some 70 kilometers( 45 miles) west of Rio de Janeiro. The person of cetaceans off this fragment of sea-coast is thought to be one of the highest concentrations in the world, constituting the deaths among over 10 percentage a massive blow to the dolphins.
The liquids off this spot of coast, being so close to such a major municipality and frequented by ships, are known to be highly polluted already. But even so, conservationists in the region often merely come across around five dead swine a month, let alone five a day. In most cases, they have died due to being caught in cyberspaces, pollution, or illegal hunting.
Those at the Boto Cinza Institute are now trying to pres the local authorities to officially remember the dolphins in the inlet as an endangered species, as well as set up a marine sanctuary in the area. This, they hope, will help safeguard the future of the dolphins, and save them from disappearing altogether.
