Comparative Analyses Reveal the Genetic Mechanism of Ambergris Production in the Sperm Whale Based on the Chromosome-Level Genome [PDF]
Animals, 2023 Sperm whales are a marine mammal famous for the aromatic substance, the ambergris, produced from its colon. Little is known about the biological processes of ambergris production, and this study aims to investigate the genetic mechanism of ambergris ...

Absorption spectra of sperm-whale ferrimyoglobin [PDF]
Biochemical Journal, 1966 1. Sperm-whale ferrimyoglobin was found to contain 0.308% of Fe, on a dry weight basis, corresponding to a molecular weight of 18130. The solid takes up moisture to an equilibrium state, and was then assayed to contain 0.280% of Fe. 2. Absorption spectra are presented for acidic ferrimyoglobin, Fe(+)(H(2)O), and its conjugate base, Fe-OH, as well as ...

The Sperm Whale and its Food [PDF]
Nature, 1896 THE services which H.S.H. the Prince of Monaco has rendered to the science of oceanography, during the last ten or twelve years, are familiar to every one interested in that department of research. First in the small schooner Hirondelle, with no power but the strong arms of his Breton crew, and later, in the large and perfectly equipped auxiliary steam

Characterization of Insulin and Glucagon Genes and Their Producing Endocrine Cells From Pygmy Sperm Whale (Kogia breviceps) [PDF]
Frontiers in Endocrinology, 2020 Insulin and glucagon are hormones secreted by pancreatic β and α cells, respectively, which together regulate glucose homeostasis. Dysregulation of insulin or glucagon can result in loss of blood glucose control, characterized by hyperglycemia or ...

The Novel Evolution of the Sperm Whale Genome. [PDF]
Genome Biol Evol, 2017 The sperm whale, made famous by Moby Dick, is one of the most fascinating of all ocean-dwelling species given their unique life history, novel physiological adaptations to hunting squid at extreme ocean depths, and their position as one of the earliest branching toothed whales (Odontoceti).
