Here's why:
* Habitat overlap: While both killer whales and swordfish are found in the ocean, their preferred habitats don't often overlap. Swordfish typically inhabit warmer waters, while killer whales are more commonly found in colder waters.
* Size and agility: Swordfish are large and strong fish, capable of reaching lengths of up to 15 feet and weighing up to 1,400 pounds. They are also known for their agility and speed, making them difficult prey for even a killer whale.
* Defensive mechanisms: Swordfish have a sharp, sword-like bill that they use to attack prey and defend themselves. This could be a deterrent to killer whales, who might be wary of encountering such a formidable opponent.
While it's not entirely impossible for a killer whale to eat a swordfish, it's not a common occurrence. They are more likely to target smaller, more vulnerable prey.
