Do narwhals kill each other

Answer 1

Yes, it's possible that Narwhals indeed kill each other. Male narwhals have been found, dead and alive, with scars and wounds to the heads and tusks. Males engage in what tends to be called playful tusking. But perhaps that gets carried away at times.

Answer 2

There have been incidents where narwhals have been observed engaging in aggressive behavior towards each other, which may result in injuries or fatalities. This behavior is usually related to competition for mates or resources, rather than intentional killing. Overall, narwhals are not known to be inherently violent towards each other.
