What do swordfish use their "swords" for?

Answered by HeidiDewar
Answer:

One of the swordfish’s favorite targets is squid. The swordfish’s razor-sharp nose, high-functioning brain and eyes compete against the squid’s lightning-fast reflexes. The swordfish use their sword to stun or kill their prey before they swallow them. They have also been reported to use their sword against much larger animals like whales or even in defense against manned submersibles. In 1967, a swordfish attacked Alvin, the deep-sea submersible.
