Scientific Committee Meeting Documents (2005)
In the first part of this report we present our results, so far, derived from the application of passive acoustic techniques to study the habitat use of vaquita. In the…
A history (1990-2015) of mismanaging the vaquita into extinction – A Mexican NGO’s perspective
Cantú-Guzmán, Juan Carlos; Olivera-Bonilla, Alejandro; Sánchez-Saldaña, María Elena
Journal of Marine Animals and Their Ecology (2015)
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…

Belanger, Michael; Askin, Nesime; Wittnich, Carin
Journal of Marine Animals and Their Ecology (2015)
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…
Construction of ethogram of the captive Yangtze finless porpoises, Neophocaena phocaenoides asiaeorientalis
Xiao, J.; Wang, D.
Acta Hydrobiologica Sinica (2005)
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…
Growth and reproduction of the finless porpoise in southern China
Jefferson, T. A.; Robertson, K. M.; Wang, J. Y.
The Raffles Bulletin of Zoology (2002)
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
Jefferson, T.A.; Hung, S.K.
Mammalian Species (2004)
(...) 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…

Reeves, Randall R.; Jefferson, Thomas A.; Kasuya, Toshio; Smith, Brian D.; Wang, Ding; Wang, Peilie; Wells, Randall S.; Würsig, Bernd; Zhou, Kaiya
Biology and Conservation of Freshwater Cetaceans in Asia (2000)
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…
Homosexual and masturbating behaviors in a group of captive Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis)
ZHANG, Changqun; ZHENG, Yang; PLATTO, Sara; HAO, Yujiang; WANG, Ding
Acta Theriologica Sinica (2015)
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 populations of Neophocaena in Chinese waters
Gao, Anli; Zhou, Kaiya
Acta Theriologica Sinica (1995)
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 populations of Neophocaena in Chinese waters
Gao, Anli; Zhou, Kaiya
Acta Theriologica Sinica (1995)
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…
