First Record of a Presumed Risso's Dolphin Calf Associated With a Bottlenose Dolphin in the Mediterranean Sea

Ecology and Evolution
Risso's dolphins Grampus griseus and common bottlenose dolphins Tursiops truncatus typically occur in distinct habitats in the Mediterranean Sea. Along the Catalan coast (north‐eastern Iberian Peninsula), bottlenose dolphins are frequently observed ...

Toxoplasma gondii in cetaceans of Brazil: a histopathological and immunohistochemical survey

Revista Brasileira de Parasitologia Veterinária
Toxoplasmosis is a parasitic disease caused by the protozoan Toxoplasma gondii. In cetaceans, T. gondii infection is a significant cause of morbidity and mortality. Despite the worldwide range and broad cetacean host record of T.

Persistent Organic Pollutants and Mercury in Genetically Identified Inner Estuary Bottlenose Dolphin (Tursiops truncatus) Residents of the Guayaquil Gulf, Ecuador: Ecotoxicological Science in Support of Pollutant Management and Cetacean Conservation

Frontiers in Marine Science, 2020
The bottlenose dolphin is one of the most common cetaceans found in the coastal waters, estuaries, and mangroves of Ecuador. However, its population size is gradually declining in the Gulf of Guayaquil, and anthropogenic factors including habitat ...

Radiographic Assessment of Bone Maturation: A Tool to Estimate Sexual Maturity in Common Dolphins (Delphinus delphis)?

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Accurate inference of sexual maturity is fundamental to interpreting marine mammal life histories and population structure. Using Bayesian logistic regression models with a hierarchical ordinal (HOF‐style) parameterisation and canonical analysis of principal coordinates (CAP), we evaluate skeletal metrics in the pectoral flippers of common ...

Life History Parameters of Indian Ocean Humpback Dolphins Sousa plumbea Off KwaZulu‐Natal, South Africa

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT For the effective conservation of coastal cetaceans, such as Indian Ocean humpback dolphin, Sousa plumbea, currently listed as “Endangered” by the International Union for the Conservation of Nature (IUCN), information on its life history is urgently required.

Investigating the relative influence of genetic drift and natural selection in shaping patterns of population structure in Delphinids (Delphinus delphis; Tursiops spp.) [PDF]

, 2010
Speciation models relying on geographic barriers to limit gene flow gather widespread consensus, but are insufficient to explain diversification in highly mobile marine organisms.

Assessment of the genetic diversity of Atlantic bottlenose dolphin (Tursiops truncatus) strandings in the Mississippi Sound (USA).

PLoS ONE
The common bottlenose dolphin (Tursiops truncatus) is a key marine mammal species in the Gulf of Mexico, playing an essential role as a top predator. This study investigates the genetic diversity and population structure of bottlenose dolphins stranded ...

Balancing Aerobic and Anaerobic Metabolism, and Its Effect on Recovery Time in Freely‐Diving Steller Sea Lions (Eumetopias jubatus)

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT As breath‐hold divers, marine mammals must coordinate their use of both aerobic and anaerobic metabolism to maximize their time at depth. One indication of the relative reliance between these two energy‐producing systems is the aerobic dive limit (ADL), defined as the dive duration where post‐dive blood lactate concentrations surpass resting ...

Atypical residency of short-beaked common dolphins (Delphinus delphis) to a shallow, urbanized embayment in south-eastern Australia [PDF]

Royal Society Open Science, 2016
Short-beaked common dolphins (Delphinus delphis) are typically considered highly mobile, offshore delphinids. This study assessed the residency of a small community of short-beaked common dolphins in the shallow, urbanized Port Phillip Bay, south-eastern
