I just read an article about a massive dolphin die off here. http://www.scientificamerican.com/article.cfm?id=massive-dolphin-die-off-in-peru-may-remain-a-mystery In Lima Peru a retired fisherman reported around 1,500 dolphins washing up dead on Peru’s northern coast. At first many experts didn’t believe it until they saw it. Experts say the causes could be acoustic impact from testing for oil or perhaps an unknown virus or other pathogen. Dr. Yaipen is one of the experts that has been studding this case, he has examined about 20 dead dolphins. From what he found they all showed middle-ear hemorrhage and fracture of the ear’s periotic bone, lung lesions and bubbles in the blood. To him, that suggests that a major acoustic impact caused injury, but not immediate death. Most of the dolphins were alive when they beached, or had died very recently. Now, the death toll could be as high as 2,800. Peru’s massive dolphin die-off is among the largest ever reported worldwide.
What are some other theories of how these dolphins are dying?
How can we stop this? What can we learn from this?
