This amazing creature also known as a “sea cow” was protected under the Endangered Species Act of 1973 as well as the Florida Manatee Sanctuary Act of 1978. They are gentle, slow moving sea creatures that inhabit the coastal waters here in Florida. Ranging in size from 800-1200 pounds. Although protected their biggest threat are boaters. Because they move so slow, they are often injured unintentionally by boat propellers. Many coastal regions throughout the state have “manatee zones” where by law, speed must be reduced to a minimum in order to help prevent injuries.
