Sonar Device May Prevent Manatee-Boat Collisions

Researchers are developing a sonar system to help boaters steer off a collision course with the Florida manatee (Trichechus manatus Linneaus). The technology could be the difference between population growth and decline in the endangered species.

In 2002, 95 of the 305 recorded manatee deaths resulted from boat collisions, making it the leading cause of death for the slow-moving animals. The remaining manatee population is estimated to be less than 3,300, according to conservation groups.
