Cardiomyopathy in stranded pygmy and dwarf sperm whales

Journal of the American Veterinary Medical Association, 1985
SUMMARY Necropsy and histologic examinations were performed in 23 pygmy sperm whales (Kogia breviceps) and 6 dwarf sperm whales (Kogia simus) that had been stranded singly or in cow-calf pairs along the southeastern coastline of the United States.

GASTROINTESTINAL LEIOMYOSARCOMA IN A PYGMY SPERM WHALE (KOGIA BREVICEPS)

Journal of Zoo and Wildlife Medicine, 2013
An adult male pygmy sperm whale (Kogia breviceps) was stranded within a tidal pool on Fernandina Beach on the north Florida Atlantic coast (USA) and expired soon after discovery. Necropsy findings included a small intestinal mass markedly expanding the intestinal wall and partially obstructing the lumen.

Composition of milk of the pygmy sperm whale (Kogia breviceps)

Comparative Biochemistry and Physiology Part A: Physiology, 1978
Abstract 1. 1. A 315cm lactating female pygmy sperm whale, Kogia breviceps , accompanied by a 156cm female calf stranded on south Miami Beach, Dade County, Florida, on 13 March 1974, were used in the experiment. 2. 2. A sample of milk from the lactating female contained less fat and more lactose than most cetecean milks previously analyzed.

Long-term monitoring of Physeteroidea (sperm whales, dwarf, and pygmy sperm whales) in the Central and Western Pacific

Journal of the Acoustical Society of America, 2016
The superfamily Physeteroidea includes three extant species: the sperm whale (Physeter macrocephalus), the dwarf sperm whale (Kogia sima), and the pygmy sperm whale (K. breviceps). Despite extreme difference in size between the Kogia spp. and their large Physeter relative, all three share ecological and acoustic traits relating to their deep-diving ...

Kogia breviceps (Pygmy sperm whale)

1974
Skin and lung biopsies were grown from a male specimen washed ashore 1971 in San Diego, California, USA, identified as this species by skull preparation and body conformation. The karyotype of the female was donated by Dr. Debbie Duffield, Los Angeles, California. It came from cornea preparations of a specimen captured in the Atlantic Ocean in 1972.

223 DESCRIPTION OF GENITALIA AND SPERM RECOVERED POSTMORTEM FROM A PYGMY SPERM WHALE, KOGIA BREVICEPS

Reproduction, Fertility and Development, 2005
A pygmy sperm whale (Kogia breviceps; adult male; 350 kg) was stranded and died on a beach near Cabo Bustos (Asturias, North of Spain) on March 12th, 2005. Finding specimens of this species is a rare event on Spanish shores, although this whale is not considered endangered. Postmortem examination was performed 24 h later.

Influence of mercury and selenium chemistries on the progression of cardiomyopathy in pygmy sperm whales, Kogia breviceps

Chemosphere, 2012
More than half of pygmy sperm whales (Kogia breviceps) that strand exhibit signs of cardiomyopathy (CMP). Many factors may contribute to the development of idiopathic CMP in K. breviceps, including genetics, infectious agents, contaminants, biotoxins, and dietary intake (e.g. selenium, mercury, and pro-oxidants). This study assessed trace elements in K.

Bilateral Polycystic Kidneys and Focal Renal Cystadenoma in a Pygmy Sperm Whale (Kogia breviceps)

Journal of Wildlife Diseases, 2019
An adult male pygmy sperm whale ( Kogia breviceps) stranded alive at a beach in Florida, US, in 2016. Main postmortem examination findings included bilateral multifocal variably sized renal cysts, focal renal cystadenoma, and mild dilation of the renal pelvises. The role of these renal lesions in the stranding of this whale is unknown.

Neuron numbers in sensory cortices of five delphinids compared to a physeterid, the pygmy sperm whale

Brain Research Bulletin, 2005
With its large mass and enormous gyrification, the neocortex of whales and dolphins has always been a challenge to neurobiologists. Here we analyse the relationship between neuron number per cortical unit in three different sensory areas and brain mass in six different toothed whale species, five delphinids and one physeterid. Cortex samples, including
