Adaptive features of aquatic mammals' eye [PDF]
Anatomical Record, 2007 AbstractThe eye of aquatic mammals demonstrates several adaptations to both underwater and aerial vision. This study offers a review of eye anatomy in four groups of aquatic animals: cetaceans (toothed and baleen whales), pinnipeds (seals, sea lions, and walruses), sirenians (manatees and dugongs), and sea otters.

Passive electroreception in aquatic mammals
Journal of Comparative Physiology A, 2012Passive electroreception is a sensory modality in many aquatic vertebrates, predominantly fishes. Using passive electroreception, the animal can detect and analyze electric fields in its environment. Most electric fields in the environment are of biogenic origin, often produced by prey items.

Evoked Potential Audiometry in Aquatic Mammals
Advances in Experimental Medicine and Biology, 2012Investigation of the influence of noise on the hearing of aquatic mammals requires appropriate methods of audiometry to assess any temporal or permanent hearing sensitivity shift. The auditory evoked potential (AEP) method is widely used for this purpose. It does not require long training of the subject, is not time consuming, and therefore may be used

Collective decision-making in aquatic mammals
Mammal Review, 2023 ABSTRACTCollective decision‐making is an essential part of day‐to‐day life for group‐living animals. These decisions can be unshared (e.g. leadership) or shared (e.g. consensus).Aquatic mammals face particular challenges when making collective decisions, including a three‐dimensional habitat that can make group coordination and collective navigation a ...

Conservation of Amazonian aquatic mammals
Aquatic Conservation: Marine and Freshwater Ecosystems, 2021Abstract Aquatic mammals worldwide are highly threatened in freshwater ecosystems where they are affected by direct human activities (e.g. hunting) as well as indirect human alteration of freshwater ecosystems (e.g. dams, mining activity). Although aquatic mammals of the Amazon Basin are experiencing many growing threats, little is known about the ...

Cone visual pigments of aquatic mammals
Visual Neuroscience, 2005It has long been hypothesized that the visual systems of animals are evolutionarily adapted to their visual environment. The entrance many millions of years ago of mammals into the sea gave these new aquatic mammals completely novel visual surroundings with respect to light availability and predominant wavelengths.

Morbillivirus infections in aquatic mammals
Journal of Comparative Pathology, 1998Morbillivirus infections which were not documented in aquatic mammals until 1988, have caused at least five epizootics in these species during the last 10 years. Affected populations include European harbour seals (Phoca vitulina) and grey seals (Halichoerus grypus) in 1998, Baikal seals (Phoca siberica) in Siberia from 1987-1988, striped dolphins ...

Surfactant from diving aquatic mammals
Journal of Applied Physiology, 2004Diving mammals that descend to depths of 50-70 m or greater fully collapse the gas exchanging portions of their lungs and then reexpand these areas with ascent. To investigate whether these animals may have evolved a uniquely developed surfactant system to facilitate repetitive alveolar collapse and expansion, we have analyzed surfactant in ...

Effects of endocrine disruptors in aquatic mammals
Pure and Applied Chemistry, 2003In the last few decades, various studies have shown that aquatic mammals are sensitive to the toxicological effects of certain xenobiotic compounds, including the large class of endocrine-disrupting chemicals (EDCs). Since some EDCs, particularly organochlorines, tend to bioaccumulate and biomagnify in the aquatic food chain, various aquatic mammals ...

Morbillivirus Infections in Aquatic Mammals: A Brief Overview
Journal of Veterinary Medicine Series A, 2005SummarySince 1987, at least eight morbillivirus infection (MI) epidemics have caused mass mortality of several free‐living pinniped and cetacean populations around the world. The responsible agents, all belonging to the genus Morbillivirus (family Paramyxoviridae), have been characterized as either ‘canine distemper virus’ strains, infecting pinnipeds,
