Molecular Evidence of a Captive-Born Intergeneric Hybridization Between Bottlenose and Risso’s Dolphins: Tursiops truncatus × Grampus griseus
Natural hybridization occurs rarely in mammals, but it is thought to have the potential to produce viable hybrid offspring in cetaceans more easily than in other mammals. Among cases of cetacean hybridization, hybrids between bottlenose dolphins (Tursiops truncatus) and Risso’s dolphins (Grampus griseus) have been documented in both the wild and in captivity. However, until now, no molecular ev...
متن کاملHearing measurements from a stranded infant Risso's dolphin, Grampus griseus.
An infant Risso's dolphin (Grampus griseus) was rescued from the beach in Southern Portugal, and an audiogram was measured using auditory evoked potentials (AEP) and envelope following response (EFR) techniques for frequencies from 4 to 150 kHz. The stimuli used were custom sinusoidally amplitude-modulated (SAM) tone-bursts, and the AEP responses were collected, averaged and analyzed to quantif...
متن کاملRISSO'S DOLPHIN (Grampus griseus): Western North Atlantic Stock

Off the northeast U.S. coast, Risso's dolphins are distributed along the continental shelf edge from Cape Hatteras northward to Georges Bank during spring, summe...
متن کاملRISSO'S DOLPHIN (Grampus griseus): Western North Atlantic Stock
STOCK DEFINITION AND GEOGRAPHIC RANGE Risso's dolphin is distributed worldwide in tropical and temperate seas. Risso's dolphins generally have an oceanic range, and occur along the Atlantic coast of North America from Florida to eastern Newfoundland (Leatherwood et al. 1976; Baird and Stacey 1990). Off the northeast USA coast, Risso's dolphin is distributed along the continental shelf edge from...
متن کاملThe Cochlea of the Dolphin, Tursiops truncatus: General Morphology.
The anatomy of the cochlea of the dolphin Tursiops truncatus was studied in a number of specimens after fixation by vital perfusion, cellodin embedding, and serial sectioning. The results reveal the general structural relations and cellular detail up to the limits of light microscopy. A description is given of the variations of structure along the course of the cochlea, in which there are many ...
