The West Indian manatee (Trichechus manatus) is a manatee, and the largest surviving member of the aquatic mammal order Sirenia (which also includes the dugong and the extinct Steller's sea cow).
The West Indian manatee is a species distinct from the Amazonian manatee (T. inunguis), and the African manatee (T. senegalensis). Based on genetic and morphological studies, the West Indian manatee is divided into two subspecies, the Florida manatee (T. m. latirostris) and the Antillean or Caribbean manatee (T. m. manatus). However, recent genetic (mtDNA) research suggests that the West Indian manatee actually falls out into three groups, which are more or less geographically distributed as: (1) Florida and the Greater Antilles; (2) central and northern South America; and (3) northeastern South America.

“Biography is a very definite region bounded on the north by history, on the south by fiction, on the east by obituary, and on the west by tedium.”
—Philip Guedalla (1889–1944)
“This, it will be remembered, was the scene of Mrs. Rowlandson’s capture, and of other events in the Indian wars, but from this July afternoon, and under that mild exterior, those times seemed as remote as the irruption of the Goths. They were the dark age of New England.”
—Henry David Thoreau (1817–1862)
