The swordfish is found and caught often during an NJ Deep Sea fishing trip. We have caught swordfish from 50 pounds up to 285 pounds.

The swordfish is primarily swims at depths of 650-1970 feet and water temperatures of 64 to 71°F. Although mainly a warm-water species, the swordfish has the widest temperature tolerance of any billfish, and can be found in waters from 41-80°F. The swordfish is commonly observed in surface waters.

Here is some information for those of you interested in scientific terms and additional details:

Family: Xiphiidae (sole member of this family)

Genus and Species: Xiphias gladius

Description: Translated to English, the Latin term gladius means "sword", referring to the long sword-like bill. This fish can swim to depths of 2,100 feet or greater, where the water temperature may be just above freezing. One adaptation which allows for swimming in such cold water is the presence of a "brain heater," a large bundle of tissue associated with one of the eye muscles, which insulates and warms the brain. Blood is supplied to the tissue through a specialized vascular heat exchanger, similar to the counter current exchange found in some tunas. This helps prevent rapid cooling and damage to the brain as a result of extreme vertical movements.
