According to:
http://www.otterproject.org/site/pp.asp?c=8pIKIYMIG&b=256015
"Why are California sea otters dying? Sea otters die from a long list of causes including entanglement in fishing nets, gun shot, boat strike, and shark bite. But, the largest and most unusual cause of death is 'disease'. About 50% of all mortality is due to a variety of diseases. Otters are being inflicted with diseases from land, being washed into the ocean from sewage and non-point sources. Also, sea otters have huge chemical contaminant loads (DDT, PCB, and butyltins); there is considerable and growing evidence that the otter's immune system is weakened. So, an immune system weakened sea otter is swimming in a thickening soup of disease."
