Pflege und Haltung der Seekühe (Trichechus) nebst Beiträgen zu ihrer Biologie.
Pallasia (Dresden) 2(2): 58-67, 113-133, pls. 5-6; 2(3): 167-180, 213-230, 2 tabs. 2 figs.
–Perhaps the most elaborate anecdotal account of the captive biology of sirs. yet written. After listing and discussing 24 instances of manatees kept in captivity (59-63), Vosseler describes the capture and transport of two T. inunguis from Brazil to Germany, and gives detailed advice on transporting manatees by sea and land (63-67, 113-114). He then describes many aspects of the biology and life in captivity of the two Amazonian specimens in Hamburg, including: captive conditions (114-119), feeding (including coprophagy and eating meat and fish) and defecation (119-129), illnesses (129-133), growth and external measurements (167-173), supposed sexual dimorphism of the tail, flipper, and head (173-175), sexual behavior (175-180), characteristics of the epidermis (213-217), experiments on their senses of taste and smell (217-220), appearance of their eyes (220), hearing (220-221), movements, breathing, sleep, and locomotion on land (221-225). (Their subsequent fatal illnesses are described in Vosseler, 1930.) Notes that their feeding and activity are not exclusively nocturnal (226), and that manatees are compatible with other species in zoo exhibits (227); extols the value of sirs. to zoos and the relative ease of keeping them (228-230).
Finally and most unexpectedly, this work includes some (rather insignificant) observations and remarks on Dugong in German East Africa and the author's unsuccessful attempts to determine whether they use their tusks in feeding (225-226).
