Swordfish are often referred to as piscivores creatures. This means that they prey on other fish species such as the barracuda, herrings, mackerels, tuna, cods, bluefish, and even squids. Two things they rely on to hunt are their swords and speed.

Researchers have found that their remarkable swimming speed enables them to outswim most other fish in the water. The swordfish will use its sword-shaped bill to stun and incapacitate their prey before they consume them. When they are young, swordfish will typically stick to a diet of zooplankton.
