Behavioural responses of captive common dolphins Delphinus delphis to a ‘Swim-with-Dolphin’ programme

Applied Animal Behaviour Science, 2003
Abstract We monitored the effects of a ‘Swim-with-Dolphin’ (SWD) programme on the behaviour of three female common dolphins. They were studied from January 1999 to July 1999 at Marineland, Napier, New Zealand. Before, during and after SWD sessions we recorded: (1) the use of a refuge area, (2) the frequencies and location of surfacing and (3) the ...

Tetraphyllidean Cysticerci in the Peritoneal Cavity of the Common Dolphin

Journal of Wildlife Diseases, 1997
Cysticerci of the cestodes Monorygma grimaldii and Phyllobothrium delphini were encountered during necropsy of an adult common dolphin (Delphinus delphis) found dead on the southeastern coast of Australia. Monorygma grimaldii cysticerci were found within highly organized retroperitoneal cysts, whereas P.

Spatial segregation and interspecific killing of common dolphins (Delphinus delphis) by bottlenose dolphins (Tursiops truncatus)

acta ethologica, 2021
We described the spatial segregation of two species of cetaceans, the common dolphin and the bottlenose dolphin. We also document the first direct observation of interspecific killing of a common dolphin by bottlenose dolphins and of interspecific necrophilia in cetaceans. The study was conducted from 2014 to 2019 in the Ria de Arousa (Northwest Spain).

Common dolphin morphotypes: Niche segregation or taxonomy?

Journal of Zoology, 2011
In the extensive geographical distribution of the common dolphin, several morphotypes of uncertain taxonomic status, identified by the relative length of their rostra, have been established. We investigated variation in skull morphometrics and isotopic signatures of carbon and nitrogen (δ13C and δ15N) in individuals from the subtropical waters of the ...

MORBILLIVIRUS INFECTION IN STRANDED COMMON DOLPHINS FROM THE PACIFIC OCEAN

Journal of Wildlife Diseases, 1998
From August 1995 to August 1997, six of 18 common dolphins (Delphinus delphis) that stranded along beaches of southern California (USA) tested antibody positive for dolphin morbillivirus (DMV). Titers ascertained by virus neutralization ranged from 1:50 to 1:910 while those determined by ELISA ranged from 1:80 to 1:195.

FETAL OMPHALOCELE IN A COMMON BOTTLENOSE DOLPHIN (TURSIOPS TRUNCATUS)

Journal of Zoo and Wildlife Medicine, 2013
A routine pregnancy ultrasound examination of a 30-yr-old, multiparous, common bottlenose dolphin, Tursiops truncatus, detected an approximately 16-wk (gestational age) fetus with an omphalocele, an abdominal wall defect at the base of the umbilical cord. Throughout the pregnancy, ultrasound allowed for identification of the omphalocele contents, which

Changes in the occurrence of common dolphins, striped dolphins and harbour porpoises in the English Channel and Bay of Biscay

Journal of the Marine Biological Association of the United Kingdom, 2008
Regular monitoring of the status of cetacean populations is essential for conservation, policy and management. By using a passenger ferry as a scientific research platform, this study provides information on seasonal, annual and longer-term changes in the occurrence of three cetacean species along a relatively fixed transect through the English Channel
