Narwhal
Monodon monocerosAlso known as Unicorn of the Sea, Narwhale, Moon Whale
Narwhals navigate the dense pack ice of the high Arctic, using an incredibly sophisticated echolocation system to find breathing holes and hunt in pitch-black depths. Their most famous feature, a long spiral tusk found primarily on males, is actually a modified tooth packed with millions of nerve endings that can detect changes in water temperature and salinity. These social whales travel in tight-knit pods, communicating through a complex repertoire of clicks, squeaks, and whistles.

LC
Observe from a safe distance on guided vessel tours to avoid disrupting their sensitive acoustic communication.
Extremely vulnerable to climate change, which reduces sea ice cover, and acoustic pollution from shipping and industrial activity.
Never approach pods in motorized vessels; rely on experienced local guides who follow strict marine mammal viewing guidelines.- Listen Closely: Use a hydrophone during boat tours to hear their diverse array of clicks and whistles.
- Watch the Ice: Look for their mottled grey backs surfacing in narrow cracks of pack ice during spring migrations.
- Respect the Quiet: Keep boat engines at idle speed to prevent interfering with their highly sensitive echolocation.
