【Abstract】 Twenty dead finless porpoises (Neophocaenaa phocaenoides) are got from the coastal waters between Xiamen and Zhangpu, Fujian Province. According to the prickles on the back, it is obvious that two subspecies. N. p. phocaenoides (81. 0 % ) and N. p. sunameri (19. 0 % ) occur simultaneously in this area. The morphology and population structure are studied, and blubber and inner organs are weighed. Furthermore, the stomach contents are analyzed carefully.更多还原
