How do narwhals hunt or find its food?

Narwhals primarily hunt by using echolocation to locate their prey, which includes fish and squid, in the dark waters of the Arctic. They dive to significant depths, often exceeding 1,500 meters, and can hold their breath for up to 25 minutes while searching for food. Once they detect their prey, they use their long tusks and agile bodies to catch and consume it. Social hunting strategies may also be employed, particularly when targeting larger schools of fish.
