Billfish & Cudas

Istiophoriformes

Billfish are characterized by their large prominent bills, (or rostra), spear-like nose, and their large body size, while Barracudas, also large, are known for their menacing appearance and ferocious behavior.

 Barracudas are actually a surprisingly large family with 28 species of Cuda.

Many people mistakenly call all Billfish, "Swordfish." But Swordfish are actually the only species in their family, Xiphiidae, while Marlin and Sailfish make up the family, Istiophoridae.

Billfish & Cudas Info:

Size -Average 10ft but can reach up to 16ft.

Billfish are characterized by their large prominent bills, (or rostra), spear-like nose, and their large body size, while Barracudas, also large, are known for their menacing appearance and ferocious behavior.

Found worldwide in tropical to temperate waters in the open ocean. Billfish can primarily be found in the Atlantic, and Barracudas tend to live near the surface in coral reefs and sea grasses in both the Pacific, and Atlantic Oceans.

They feed mostly on Bony Fish, Crustaceans, and Cephalopods.

Marlins and Swordfish are highly migratory and pelagic. 

They have been known to spear boats but this behavior is believed to be accidental.

They are highly valued game fish and sought after by port fishermen.

Barracudas have been reported to mistakenly bite a swimmer on occasion, but it would be a reach to declare them a true danger or threat to humans.

There are 12 species of Billfish divided into two families and 28 species of Barracuda in its single family.

They are apex predators feeding on a wide variety of prey.

They are closely related to mackerels and tuna.
