Der Manati, Trichechus senegalensis, im Rio Geba, Guinea-Bissau.
Natur und Museum (Frankfurt a. M.) 125(12): 402-409. 1 tab. 9 figs. Dec. 1, 1995.
–Repr.: Säugetierk. Mitt. 44(3): 121-128, 1999. Presents results of two surveys by boat and interview (including the successful use of sonar to detect submerged manatees), with some notes on the natural history of African manatees. (The survey team included personnel from the Toba Aquarium in Japan, which soon thereafter acquired African manatees from this region for display.) Despite their continued hunting by gun and net, Schuhmann regards manatees as abundant in Guinea-Bissau, having detected the presence of 109 along 140 km of river; but his extrapolation of this figure to a guesstimate of some 10,000 manatees in the entire country seems excessive.
