Is a swordfish teeth sharp?
Full grown swordfish have no teeth.
A swordfish protects itself with its "sword", because it has no other useful weapon, such as teeth and claws. For example:a shark uses its teeth for protection and an octupus uses its ink spray so its enemies won't see them but a swordfish uses its sword-like nose to defeat its enemies and predators. 2 male swordfish will have a swordfight, while only one swordfish under attack will try and stab its enemy.
