General Habitat and Food Preferences An oceanic species, the Swordfish is primarily a midwater fish found at depths of 650 to almost 2000 feet.

These fish are most often solitary in nature.

They feed primarily on sardines, squids, flying fish, and other medium-sized fishes.
Did You Know? The Swordfish has a large bundle of tissue which insulates and warms the brain. This "brain heater" allows the fish to swim in cold water.

The Swordfish sometimes uses it sword by slashing its prey and injuring it making it easier to catch and eat. They do not use their sword as a spear.
Common Lures and Baits Swordfish are often seen basking on the surface during the day but many times won't bite bait trolled past them.

Drift fishing at night using large squid is often employed. Small light sticks are often added just above the hook.
Typical Sizes Caught Swordfish are commonly caught in the range of 75 to 100 pounds by anglers.
