Would an eagle eat a swordfish?
No, swordfish live in deeper waters than an eagle would hunt in. Besides, no eagle is capable of carrying a swordfish to land, let alone lift it out of the water or even catch it. If you mean to suggest a carcass that drifted onto the beach, maybe, if it was fresh enough to be appealing to such a bird.
Why do swordfish fight each other?
Swordfish often fight each other for the right to mate with females or for territory. These fish are very large and very territorial and will often even fight with humans who enter their area.
