Strange attractor of a narwhal (Monodon monoceros).
PLoS Computational Biology, 2022 Detecting structures within the continuous diving behavior of marine animals is challenging, and no universal framework is available. We captured such diverse structures using chaos theory.

Biology and Cultural Importance of the Narwhal
Annual Review of Animal BiosciencesThough narwhal have survived multiple ice ages, including 2.5 Ma and the last interglacial period with warming temperatures, Arctic climate change during the Anthropocene introduces new challenges. Despite their evolutionary connection to Arctic Pleistocene fossils, narwhal archeocete ancestors from the Pliocene ( Bohaskaia monodontoides ) and Miocene

How adaptable are narwhal? A comparison of foraging patterns among the world's three narwhal populations [PDF]
Ecosphere, 2013 How organisms will fare in the face of climate change depends on their behavioral adaptability to changing conditions. Adaptability in foraging behavior will be particularly critical as food web changes are already occurring in Arctic regions. Stomach contents from narwhals (Monodon monoceros) in the Baffin Bay (BB) population have suggested that ...

Singulonics: narwhal-shaped wavefunctions for sub-diffraction-limited nanophotonics and imaging
ELightThe diffraction limit, rooted in the wave nature of light and formalized by the Heisenberg uncertainty principle, imposes a fundamental constraint on optical resolution and device miniaturization.

Evidence of stereotyped contact call use in narwhal (Monodon monoceros) mother-calf communication.
PLoS ONE, 2021 Narwhals (Monodon monoceros) are gregarious toothed whales that strictly reside in the high Arctic. They produce a broad range of signal types; however, studies of narwhal vocalizations have been mostly descriptive of the sounds available in the species'

Frontiers in Marine Science, 2021 Deep diving air-breathing species by necessity must balance submergence time and level of exercise during breath-holding: a low activity level preserves oxygen stores and allows longer duration submergence whereas high activity levels consume oxygen ...

A review of the Strongylophthalmyia coarctata subgroup (Diptera, Brachycera, Strongylophthalmyiidae) from China, with the descriptions of three new species [PDF]
ZooKeys, 2023 The species belonging to the Strongylophthalmyia coarctata subgroup of the S. punctata group (Diptera: Brachycera: Strongylophthalmyiidae) from China are reviewed. Six species are recognized, including three new species: S. corniculata sp.

Polar bear attack on a juvenile narwhal
Fauna Norvegica, 1990 A juvenile female narwhal Monodon monoceros landed at Pond Inlet had several sets of scratches on the posterior part of the body. They were probably made by a polar bear Ursus maritimus in the course of an unsuccessful attack.
