Anat. Rec. 259(1): 41-51. 6 figs. + cover illus. May 1, 2000.
—Describes the anatomy of the respiratory diaphragm, redefines or renames some structures in the manatee that differ from other mammals,and discusses the diaphragm's role in buoyancy control. In manatees, the transverse septum between heart and liver is separate from the diaphragm, which does not attach to the sternum. Intestinal gas may possibly be manipulated within the abdomen to help control buoyancy and pitch.

2000Sexual dimorphism in vestigial pelvic bones of Florida manatees (Trichechus manatus latirostris).
Florida Scientist 63(3): 177-181. 2 figs. Summer 2000.
—Examination of 65 male & 64 female pelvic bones showed that dimorphic features develop in ones from animals larger than 225 cm total body length, corresponding with the onset of sexual maturity in males. Those of males increase in size & weight faster than those of females. Pelvic bones of females longer than 300 cm decrease slightly in size & weight.

—ABSTRACT: The auditory anatomy of the Florida manatee (Trichechus manatus latirostris) was investigated using computerized tomography (CT),three-dimensional reconstructions, and traditional dissection of heads removed during necropsy. The densities (kg/m3) of the soft tissues of the head were measured directly using the displacement method and those of the soft tissues and bone were calculated from CT measurements (Hounsfield units). The manatee's fatty tissue was significantly less dense than the other soft tissues within the head (p< 0.05). The squamosal bone was significantly less dense than the other bones of the head (p< 0.05). Measurements of the ear bones (tympanic, periotic, malleus, incus, and stapes) collected during dissection revealed that the ossicular chain was overly massive for the mass of the tympanoperiotic complex.
