The population of the critically endangered vaquita has decreased alarmingly to less than 100 individuals due to by-catch in legal and illegal fisheries of totoaba, shrimp, shark, and others in…
The vaquita (Phocoena sinus) is a small and very elusive porpoise that ranges in a limited geographical area in the Gulf of California, Mexico. Despite various efforts to conserve this…
Quantitative study of behavior should be preceded by precise description and definition of behavior. Therefore, an ethogram, which includes the comprehensive descriptions of the characteristic behavior of a species, should…
We studied the growth and reproduction of finless porpoises in southern China, based on 86 specimens collected as strandings or fisheries bycatches in Hong Kong, southern Fujian Province, and Taiwan.…
(...) Neophocaena phocaenoides is the only member of the family Phocoenidae without a dorsal fin (Fig. I ). In its place is a low, geographically-variable dorsal ridge (sometimes inappropriately called…
The population of finless porpoises (Neophocaena phocaenoides) that inhabits China’s Yangtze River is unique. All other known populations of the species are distributed principally in marine waters. This population is…
Similar to terrestrial mammals, male-female sexual behavior is significant for the survival and continuation of certain cetacean species. However, non-reproductive mating behaviors, i.e. homosexual behaviors and masturbation, are widespread in…
Geographical variations of postcranial skeleton among the Yangtze, Yellow Sea and South China Sea populations of the finless porpoise, Neophocaena phocaenoides, in Chinese waters were studied with t-test, covariance analysis…
Geographical variations of skull among the Yangtze, Yellow Sea and South China Sea populations of the finless porpoise, Neophocaena phocaenoides, in Chinese waters were studied using 42 skull measurements based…
