Assessing the Welfare of Cetacea
2017Most of the species from the order Cetacea appear to possess advanced cognitive abilities and close social networks and are also likely to experience different affective states comprising of more than just basic emotions. Welfare describes a balance of positive and negative affective states experienced by an individual, and this balance is a good ...

Retino-hypothalamic Connexions in Cetacea
Nature, 1964THE existence of retino-hypothalamic neural connexions in mammalian forms has long been controversial. The more recent investigations of Blumcke1 in the cat and guinea pig, of Frey2 in the guinea pig and of Knoche3,4 in man, dog and rabbit strongly suggest that a bundle of fibres leaves the optic pathway at a chiasmatic level and passes dorsalward into

The Diverse Sensory Specializations of Cetacea
The FASEB Journal, 2020Cetaceans (whales, including dolphins and porpoises) have many unique sensory adaptations that enable them to perceive and respond to stimuli underwater. These adaptations include audition, vocalization, vision, balance, chemoreception, and somatosensation.Cetaceans generate and receive sounds at both ends of the frequency spectrum, and use these ...

Cetacea are natural knockouts for IL20
Immunogenetics, 2018The Cetacea infraorder comprises a very unique group within the mammalian lineage. While sharing common ancestors with terrestrial mammals, their exclusive dependence on aquatic environments makes them attractive models to explore the landscape of molecular shifts in radical habitat transitions.

Classification and Molecular Phylogeny
2007Myths, legends, hunting, and natural history, having a common and often mixed origin, provide the evidence that allows us to investigate the past relationships between man and cetaceans. This contribution is not meant to be an exhaustive analysis. Rather, it is intended as an integrated approach to elucidate the reasons for and the nature of these ...

Studies on the fetal development of the gubernaculum in cetacea
The Anatomical Record, 1995AbstractBackground. Adult cetacean males, like non‐mammalian vertebrates and other testicond mammals, have intra‐abdominal testes. There is no evidence of a processus vaginalis in them. Testicondia in cetaceans is considered secondary as they are judged, evolutionarily, the descendants of terrestrial mammals (ungulates) with testis descent.

The Nasal Structures of Adult Cetacea
1999In adult cetaceans (Fig. 50, 51) only some of the embryonic cartilaginous structures of the nasal skull are preserved as cartilage. The cartilaginous tissue either ossifies to form independent skull bones, or it becomes integrated into the bony tissue of the dermal bones, or it is dissolved and resorbed.
