Time, pattern, and heterochrony: a study of hyperphalangy in the dolphin embryo flipper
SUMMARY The forelimb of whales and dolphins is a flipper that shows hyperphalangy (numerous finger bones). Hyperphalangy is also present in marine reptiles, including ichthyosaurs and plesiosaurs.Expand
Functional Morphology of the Nasal Complex in the Harbor Porpoise (Phocoena phocoena L.)
Toothed whales (Odontoceti, Cetacea) are the only aquatic mammals known to echolocate, and probably all of them are able to produce click sounds and to synthesize their echoes into aExpand
Quantitative neuroanatomy of the brain of the La Plata dolphin, Pontoporia blainvillei
SummaryThe brain of the La Plata dolphin, Pontoporia blainvillei, was studied with methods of quantitative morphology. The volumes and the progression indices of the main brain structures wereExpand
Morphogenesis of the brain in the harbour porpoise
Morphogenesis of the brain in a cetacean species has been investigated by means of reconstructions from serial sections of successive prenatal stages of the harbour porpoise (Phocoena phocoena). FourExpand
The dolphin brain—A challenge for synthetic neurobiology
Toothed whales (odontocetes) are a promising paradigm for neurobiology and evolutionary biology. The ecophysiological implications and structural adaptations of their brain seem to reflect theExpand
Evolutionary Morphology and Acoustics in the Dolphin Skull
Cetaceans are the most fascinating creatures in the animal kingdom. They adapted so perfectly to their aquatic habitat that it is hard to imagine they originated from typical tetrapod land mammals.Expand
Head morphology in perinatal dolphins: A window into phylogeny and ontogeny
In this paper on the ontogenesis and evolutionary biology of odontocete cetaceans (toothed whales), we investigate the head morphology of three perinatal pantropical spotted dolphins (StenellaExpand
Morphology of the pectoral girdle in the Amazon dolphin Inia geoffrensis with special reference to the Shoulder joint and the movements of the flippers
Studied the Shoulder girdle in the Amazon dolphin Inia geoffrensis in comparison with that of Tursiops truncatus and Phocoenaphocoena . In contrast to marine dolphins, in Inia the sternum takes partExpand
Neuroanatomy of Magnetoreception: The Superior Colliculus Involved in Magnetic Orientation in a Mammal
The neural substrate subserving magnetic orientation is largely unknown in vertebrates and unstudied in mammals. We combined a behavioral test for magnetic compass orientation in mole rats andExpand
Visual System Labeled by c-Fos Immunohistochemistry after Light Exposure in the ‘Blind’ Subterranean Zambian Mole-Rat (Cryptomys anselli)
The Zambian mole-rat (Cryptomys anselli) is a rodent that lives and forages underground, and under natural conditions is rarely, if ever, exposed to light. Its eye is organized as in other rodentsExpand
