* Size and Strength: Orcas are much larger and stronger than narwhals. An adult orca can weigh up to 10 tons, while a narwhal weighs around 1.5 tons. Orcas are apex predators known for their hunting prowess.
* Tusk: While the narwhal's tusk is a unique and impressive feature, it's not a weapon designed for attacking large prey. It's primarily used for display, fighting other narwhals, and possibly for foraging.
* Diet: Narwhals primarily feed on fish and squid, while orcas have a diverse diet that includes seals, fish, and other marine mammals.
While a narwhal might try to defend itself if attacked by an orca, it's highly improbable that it would be successful.
