Answer 1

11) Red tide a type of toxic algae that produces toxin known as brevrtoxin, the manatees can take in some seawater that contains toxins and causes respiratory irritation.

Ans-Congestion and Edema in the respiratory tract.

12) Calves.

15) Florida Fish and Wildlife

16) Georgia to Alabama

17) Atlantic Coast region.
