ЁЯФ╣ Why in News & Recent Development

Marine biologists published new acoustic research tracking the migration patterns and sensory role of the iconic spiral tusk in Narwhals (Monodon monoceros) amid rapid Arctic sea-ice loss.

ЁЯФ╣ Anatomical Features & Tusk Function

Narwhals are medium-sized toothed whales (Family Monodontidae, closely related to Belugas). Males possess an elongated, spiral left canine tooth that grows into a tusk up to 3 metres (10 feet) long. The tusk contains millions of sensory nerve endings, functioning as a hydrodynamic sensor to detect changes in water temperature, salinity, and pressure.

ЁЯФ╣ Habitat, Distribution & Conservation Status

Narwhals inhabit the icy coastal waters and fjords of the Arctic Ocean (Greenland, Canada, Norway, and Russia). They are classified as Near Threatened (IUCN Red List) and listed in CITES Appendix II. Major threats include Arctic warming, underwater acoustic pollution from shipping, and oil exploration.
