Manatees are chronically threatened by boat strikes in Florida's waterways, requiring speed zones and awareness to prevent trauma and death.
Boat strikes cause severe trauma - propeller lacerations through body mass, blunt force trauma from hull impact, and fractures from glancing collisions. Injured manatees suffer through wound infections, inability to swim normally, and secondary starvation if movement is impaired. The chronic nature of the problem - nearly every adult bearing scars - indicates a system-wide welfare failure where individual suffering is normalized. Speed zone enforcement and boater education are direct welfare interventions.
