manatees, aquatic mammals inhabiting florida’s rivers and coastal waters, swim close to the surface and are frequently killed in collisions with boats. to address the problem, boat traffic in manatee-populated waters is being required to maintain very low speeds. unfortunately, manatees are unable to hear low-pitched sounds and a boat’s sound lowers in pitch as the boat slows. therefore, this approach may in fact make things worse rather than better.

Fast-moving boat traffic can disturb or harm water hyacinth beds because the water hyacinth that manatees feed on develops best in water that is practically motionless.

In the scenario described in the question, it is said that manatees cannot hear the sluggish boats' low-pitched sounds, which could lead to more crashes and fatalities.

The response, if accurate, raises doubt about the findings since it makes sense for the boats to slow down even though the likelihood of hitting a manatee increases because the hyacinth that manatees eat grows best in calm water.
