Abstract Open-flow oxygen and carbon dioxide respirometry was used in Neumünster Zoo (Germany) to examine the energy requirements of six Asian small-clawed otters (Amblonyx cinerea) at rest and swimming voluntarily under water. Our aim was to compare their energy requirements with those of other warm-blooded species to elucidate scale effects and to test whether the least aquatic of the three otter species differs markedly from these and its larger relatives. While at rest on land (16 °C, n… 
Biology and Ecology of Asian Small-Clawed Otter Aonyx cinereus (Illiger, 1815): A Review
The Asian small-clawed otter is the smallest among the 13 extant species of otters. It has a large distribution range extending from India in South Asia through Southeast Asia up to Taiwan and
Swimming metabolic rates vary by sex and development stage, but not by species, in three species of Australian otariid seals
The seals in this study appear to operate at their physiological optimum during submerged swimming, however, the higher metabolic rates of young and female fur seals and sea lions may limit their scope for increasing foraging effort during times of resource limitation.

Despite the high energetic costs of a semiaquatic existence, these animals represent modern analogs of evolutionary intermediates between ancestral terrestrial mammals and their fully aquatic descendants, and indicate which potential selection factors and mechanical constraints may have directed the evolution of more derived aquatic forms.
The study aimed to ascertain the proximate cause of ‘begging’ behaviour in a group of captive Asian short-clawed otters (Aonyx cinereus). Two alternative hypotheses were tested by manipulating
Variation in digestive efficiency of captive North American river otters (Lontra canadensis) on various diets.
To further understand energy handling by river otters on diets used in zoologic institutions and to better provide the nutrient dense diets this active species requires, additional studies quantifying energetic parameters for captive otters of various genders, ages, and reproductive conditions on other diet types are needed.
A non‐aquatic otter (Mammalia, Carnivora, Mustelidae) from the Late Miocene (Vallesian, MN 10) of La Roma 2 (Alfambra, Teruel, Spain): systematics and functional anatomy
A mosaic of features strongly suggests the possibility that the aquatic lifestyle of otters could have appeared after the initial development of the distinctive dental morphology of this specialized group of mustelids.
Diving behaviour and activity patterns of the invasive American mink, Neovison vison
This is the first study to use HMM to classify the dives of a semi-aquatic animal, and the first to use TDR temperature records to identify mammalian activity patterns, generally applicable to animals that make rapid transitions between environments and have thus far been difficult to study.
Pedalling downhill and freewheeling up; a penguin perspective on foraging
Passive ascents during prey capture appear to be an important mechanism for Magellanic penguins to capture fast- moving prey with minimal energy expenditure.
The potoroos differ from bettongs in their preference for more humid regions, whereas Aepyprymnus, although favoring similar habitat , has a greater mass than the betton gs.


Energy metabolism of underwater swimming in river-otters (Lutra lutra L.)
A still-water swim channel in conjunction with open-flow oxygen and carbon dioxide respirometry was used to examine the energy requirements of river-otters swimming voluntarily underwater in Neumünster Zoo and found that they had higher energy requirements when the animals were feeding in the channel.
Energy Requirements of Beavers (Castor canadensis) Swimming Underwater
Although beavers must compromise form and function to operate on water and on land, their energy requirements while diving amount to only 1.65 times the resting metabolic rate and compare well with those of accomplished swimmers such as aquatic mammals and birds.
Energetic requirements of under-water swimming in pygoscelid penguins were studied in Antarctica, using respirometry together with a 21 m long swim canal and externally attached devices recording the
Energy requirements of Adélie penguin (Pygoscelis adeliae) chicks
The energy requirements of Adélie penguin chicks were analysed with respect to body mass and various forms of activity and two relationships are proposed for the pooled data, one for minor activities and one for walking.
Diving energetics in king penguins (Aptenodytes patagonicus).
Dive duration in wild king penguins and the energetic cost of swimming in a 30m long swim channel were determined at Ile de la Possession, Crozet Archipelago, using external data loggers and respirometry, respectively, indicating that the aerobic dive limits of this species could be higher and oxygen consumption lower than previously reported.
The metabolic cost of swimming in marine homeotherms.
The work shows the metabolic Costs of propulsion and thermoregulation in a swimming homeotherm to be interlinked and suggests differing costs of propulsion for different modes of swimming.
Energy requirements of freely diving muskrats (Ondatra zibethicus)
The metabolic costs of spontaneous diving in the muskrat were estimated from measurements of oxygen consumption, using a purpose-built open-circuit respirometer, and suggest that underwater exercise is accompanied by an increase in energy expenditure.
Metabolism and Thermoregulation in the Sea Otter
The sea otter is the largest of the Mustelidae, being rivaled only by the giant Amazonian otter (Pteronura brasiliensis), itself threatened with extinction.
Swimming and Diving in Tufted Ducks, Aythya Fuligula , with Particular Reference to Heart Rate and Gas Exchange
During voluntary diving in tufted ducks there is a balance between the cardiovascular responses to forced submersion and to exercise in air (tachycardia and vasodilatation in active muscles), with the bias towards the latter.

Thermoregulation during swimming and resting in water was investigated for the North American mink in summer and winter pelage by measuring total heat production, heat storage, and minimum thermal conductance, and patterns of cooling for carcasses, the taxidermic mount, and swimming mink were similar.
