Age, growth, and reproduction of the finless porpoise, Neophocaena phocaenoides, in the coastal waters of western Kyushu, Japan
Shirakihara, Miki; Takemura, Akira; Shirakihara, Kunio
Marine Mammal Sci (1993)
In the coastal waters of western Kyushu, Japan, a total of 97 incidentally taken or stranded finless porpoises, Neophocaena phocaenoides, was collected for studying age, growth and reproduction. An additional…

Law, T. C.; Blake, R. W.
Marine Mammal Sci (1994)
(...) Several researchers have obtained accurate speed data on unconfined cetaceans using a variety of techniques. Hui (1989) analyzed video tapes of Delphinus delphis and Stenella attenuata filmed from a…
Development, sexual dimorphism, and individual variation in the skeleton of the finless porpoise, Neophocaena phocaenoides, in the coastal waters of western Kyushu, Japan
Yoshida, Hideyoshi; Shirakihara, Miki; Takemura, Akira; Shirakihara, Kunio
Marine Mammal Sci (1994)

Echolocation rates of two harbor porpoises (Phocoena phocoena)
Akamatsu, Tomonari; Hatakeyama, Yoshimi; Kojima, Takahito; Soeda, Hideo
Marine Mammal Sci (1994)
The rate of occurrence of click trains of two harbor porpoises (Phocoena phocoena) were counted during 14 nights. We developed an echolocation signal detection system that was harnessed to a…
Paedomorphic ossification in porpoises with an emphasis on the Vaquita (Phocoena sinus)
Mellor, Liliana; Cooper, Lisa Noelle; Torre, Jorge; Brownell, Robert L.
Aquatic Mammals (2009)
Heterochrony, the change in timing of developmental processes, is thought to be a key process shaping the numerous limb morphologies of tetrapods. Through a delayed offset in digit development, all…
