"After nearly four days of a dead manatee rotting away in the Caloosahatchee, I've been here all morning and you can see that FWC officers are investigating and cutting open the manatee to figure out what caused its death. A dead manatee was found Saturday morning in the water near Fort Myers Shores. It's since been removed, but Sean Anderson tells me this isn't the first time a manatee has washed up near the rocks this summer. It was pretty sad. I mean, it's like the second one we've seen. I don't know why they keep turning it up like that, but I mean, it's not a good sight anyone likes to see. Molly Lugie is a mammal marine biologist. Florida Fish and Wildlife records show 94 manatees have died in Lee County alone this year. The best way to determine the cause of death is with a necropsy. See, we cut open the animal, we look at every organ, see what could be going on, anything abnormal, what looks abnormal, and then we collect those samples and they're shipped off for analysis. Lugie says it can still take some time to learn the cause of death. The leading threats to manatees are human-related activities and harmful algal blooms like red tide, which we are not experiencing in our Gulf Coast."
