Remarkable consistency of spinal cord microvasculature in highly adapted diving odontocetes [PDF]

Frontiers in Physiology, 2022
Odontocetes are breath-hold divers with a suite of physiological, anatomical, and behavioral adaptations that are highly derived and vastly different from those of their terrestrial counterparts.

SEM study of Anisakis brevispiculata Dollfus, 1966 and Pseudoterranova ceticola (Deardoff and Overstreet, 1981) (Nematoda: Anisakidae), parasites of the pygmy sperm whale Kogia breviceps

Scientia Marina, 2002
Scanning Electron Microscopy (SEM) was used to study different topo-morphological characteristics of the architecture (cuticle, excretory pore, lips and adjacent structures, number and distribution patterns of caudal papillae and papillae-like structures)

KOGIA PUSILLA FROM THE MIDDLE PLIOCENE OF TUSCANY (ITALY) AND A PHYLOGENETIC ANALYSIS OF THE FAMILY KOGIIDAE (ODONTOCETI, CETACEA)

Rivista Italiana di Paleontologia e Stratigrafia, 1999
A partial skull of an odontocete cetacean from Middle Pliocene sediments of Monte Voltraio (Pisa Province, Tuscany, Italy) is examined. This fossil, erroneously referred to the family Ziphiidae and described in the past as holotype of the species ...

Pygmy sperm whale multi-omics data reveal hypoxia adaptations in deep-diving cetaceans [PDF]

BMC Biology
Background Deep-diving cetaceans tolerate acute hypoxia better than their terrestrial ancestors and shallow-diving counterparts. However, our poor understanding of how genetic factors, cellular functions, and physiological characteristics combine to ...

Survey of selected viral agents (herpesvirus, adenovirus and hepatitis E virus) in liver and lung samples of cetaceans, Brazil [PDF]

Scientific Reports
Hepatic and pulmonary lesions are common in cetaceans, despite their poorly understood viral etiology. Herpesviruses (HV), adenoviruses (AdV) and hepatitis E virus (HEV) are emerging agents in cetaceans, associated with liver and/or pulmonary damage in ...

Histochemical indications for a chemically complex signal produced by the cervical gill slit gland of the pygmy sperm whale (Kogia breviceps). [PDF]

Anat Rec (Hoboken)
Abstract The pygmy sperm whale (Kogia breviceps) possesses an exocrine gland associated with its false gill slit pigmentation pattern. The cervical gill slit gland is a compound tubuloalveolar gland that produces a holocrine secretion and displays maturational changes in size and secretory histology. While the morphology of the cervical gill slit gland
