A pioneering survey of deep-diving and off-shore cetaceans in the northern South China Sea.

Integrative Zoology, 2020
A pioneering boat-based survey was conducted in 2019, to gather baseline information regarding the presence, composition, relative abundance, and spatial distribution of deep-diving and off-shore cetaceans in the northern South China Sea (SCS).

Cetacean café coronary

Journal of Clinical Forensic Medicine, 2003
The carcass of a young adult male Indian Ocean Bottlenose dolphin (Tursiops cf aduncus) was found floating in an estuary near Adelaide, South Australia. An autopsy revealed that death had been caused by obstruction of the upper aerodigestive tract by a 660 mm Cobbler Carpetshark (Sutorectus tentaculatus).

Candidiasis in captive cetaceans

Journal of the American Veterinary Medical Association, 1982
Summary Disseminated Candida albicans infections were found or suspected in 4 captive cetaceans. Ketoconazole at a dosage of 2.5 mg/kg, bid, administered orally for 18 days, followed by 8 biweekly oral doses of levamisole hydrochloride at the rate of 9 mg/ kg, resulted in regression of clinical signs of candidiasis in an adult male Atlantic bottlenose ...

Characterization of cetacean Numt and its application into cetacean phylogeny

Genes & Genomics, 2015
The translocations of mitochondrial DNA into chromosomal DNA (nuclear mitochondrial DNA, Numt) are ubiquitous in eukaryotes including yeasts, plants, and animals. The features of Numt and the recent sequencing technology can facilitate an expanded application of Numt into a valuable phylogenetic marker for unresolved taxa.

Prostatic Lesions in Odontocete Cetaceans

Veterinary Pathology, 2018
The prostate is the only accessory male genital gland described in cetaceans. Although few studies describe the gross and histologic anatomy of the prostate in cetaceans, there is no information on pathological findings involving this organ. The prostate glands of 45 cetaceans, including 8 different odontocete species ( n = 44) and 1 mysticete, were ...

Ingestion of microplastics by fish and other prey organisms of cetaceans, exemplified for two large baleen whale species.

Marine Pollution Bulletin, 2019
Knowledge on microplastic (MP) ingestion by cetaceans is difficult to obtain. We infer the potential for MP uptake by cetaceans from the occurrence of MP in prey species.

Behavioural Ecology of Cetaceans

2002
The study of behavioural ecology examines the ways in which a species maximises its survival (and ultimately, its reproductive success) through optimal strategies of behaviour. It asks questions about the functions of behaviours, rather than describing behavioural mechanics, which is the domain of classical ethology (Krebs and Davies, 1991). In general,

The cetacean brain

Cetaceans can be considered the pinnacle of evolution in terms of brain size, with the iconic sperm whale (Physeter macrocephalus) sporting the largest brain in known evolutionary history. In this chapter, we explore behind the scenes of cetaceans encephalization quotient, understanding how an ensemble of increasingly multidisciplinary, comparative ...

Cetacean visual pigments

Vision Research, 1971
Abstract Visual pigments from marine cetaceans, as in other mammals, are homogeneous and based on the retinal-l chromophore, but show a wider range in absorption maxima. Maxima range from 497 to 486 nm and for one species to 481 nm, but with less certainty. This distribution correlates best with the dominant hue present in the habitat of each species.

On the revolution of cetacean evolution

Marine Genomics, 2018
The order of Cetacea with 88 species including Odontoceti (or toothed whales) and Mysticeti (or baleen whales) is the most specialized and diversified group of mammals. The blue whale with a maximum recorded length of 29.9 m for 173 t of weight is the largest animal known to have ever existed, and any dolphin's brain is most powerful and complex than ...
