Comparison of dolphins’ body and brain measurements with four other groups of cetaceans reveals great diversity

Ridgway, Sam H.; Carlin, Kevin P.; Van Alstyne, Kaitlin R.; Hanson, Alicia C.; Tarpley, Raymond J.
Brain, Behavior and Evolution (2016)

We compared mature dolphins with 4 other groupings of mature cetaceans. With a large data set, we found great brain diversity among 5 different taxonomic groupings. The dolphins in our…


Comparative anatomy of the bony labyrinth of extant and extinct porpoises (Cetacea: Phocoenidae)

Racicot, Rachel A.; Gearty, William; Kohno, Naoki; Flynn, John J.
Biological Journal of the Linnean Society (2016)

The inner ear anatomy of cetaceans, now more readily accessible by means of nondestructive high-resolution X-ray computed tomographic (CT) scanning, provides a window into their acoustic abilities and ecological preferences.…


Regression of the optic system in the Changjiang (Yangtze) finless porpoise (Neophoceana asiaeorientalis) as a result of lack of light

Chen, P.; Shao, Z.; Pilleri, G.
Investigations on Cetacea (1980)

(...) The research shows that the finless porpoise of the Changjiang (Yangtze river) presents an atrophy ofthe entire optic system - eye and eye muscle nerves, optic nerve, optic pathways.…


Observations on the baiji (Lipotes vexillifer) and the finless porpoise (Neophocaena asiaeorientalis) in the Changjiang (Yangtze) River between Nanjing and Taiyangzhou, with remarks on some physiological adaptations of the baiji to its environment

Zhou, K.; Pilleri, G.; Li, Y.
Investigations on Cetacea (1979)

Two species of dolphin inhabit the Changjiang (Yangtze): Lipotes vexillifer MILLER, 1918 (known as Baiji in Chinese) and the Finless porpoise, Neophocaena asiaeorientalis PILLERI and GIHR, 1972. Although quite a…


How the finless porpoise (Neophocaena asiaeorientalis) carries its calves on its back, and the function of the denticulated area of skin, as observed in the Changjiang River, China

Pilleri, G.; Chen, P.
Investigations on Cetacea (1979)

Finless porpoise mothers are able to carry their calves balanced securely on their back. This behaviour was frequently observed by the authors in the course of an expedition to the…


Ultrastructure of enamel and dentine in extant dolphins (Cetacea: Delphinoidea and Inioidea)

Loch, Carolina; Duncan, Warwick; Simões-Lopes, Paulo C.; Kieser, Jules A.; Fordyce, R. Ewan
Zoomorphology (2012)

Longitudinal and cross sections of teeth from 17 species of the Recent dolphins (Delphinoidea and Inioidea) were examined under scanning electron microscope to study the arrangement and ultrastructure of dental…


Comparative morphology of porpoise (Cetacea: Phocoenidae) pterygoid sinuses: Phylogenetic and functional implications

Racicot, Rachel A.; Berta, Annalisa
Journal of Morphology (2012)

High-resolution X-ray computed tomographic scans were used to examine pterygoid sinus morphology within extant porpoise species and one delphinid (Tursiops truncatus), in order to consider: 1) intraspecific and interspecific variation…
