"Even as a Red Tide algae bloom is wiping out a record number of manatees in southwest Florida, a mysterious ailment is killing dozens more manatees on the state's east coast. So far, state biologists have been unable to pinpoint the cause."
"Pat Rose, a former government manatee biologist who is now executive director of the Save the Manatee Club, said he could not recall another time when manatees were being killed in such numbers on both coasts at the same time.
Since last July, 55 manatees showing similar symptoms have died in the Indian River Lagoon area — 25 in just the past month, according to Kevin Baxter, a spokesman for the state's Fish and Wildlife Research Institute in St. Petersburg."
