Cetaceans display numerous anatomic and physiologic adaptations to life in a dense, three-dimensional medium. Their bodies have changed radically from those of their terrestrial ancestors, yet their behaviors and types of social organization are broadly similar to those of animals on land.

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, 1982Summary 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, 2015The 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.

Behavioural Ecology of Cetaceans
2002The 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,

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 ...

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, 2018The 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 ...

The ethmoid and presphenoid of cetaceans
Journal of Morphology, 2016ABSTRACTA cribriform plate, a perpendicular plate, and two lateral masses are major components of the ethmoid bone of mammals. Notwithstanding the noticeable bone, virtually sitting in the center of the skull, extensive modifications of the skull of modern cetaceans, especially odontocetes (toothed whales), and the lack of clarity as to what ...
