About this species

Species identity

Xiphias gladius, commonly known as the swordfish, is a large pelagic fish that typically reaches 2–3 meters in length. It lives in the open ocean and is capable of moving between surface waters and deeper layers. Its streamlined body and long, flat bill are adapted for fast swimming and striking prey.

Where it lives

Xiphias gladius is found in tropical, temperate, and some subtropical waters of the Atlantic, Pacific, and Indian Oceans. It is widely distributed across the global ocean, making it a highly migratory species.

It occurs from surface waters down to deeper zones, often moving vertically between warm surface layers and cooler depths.

This species prefers open ocean environments and is commonly associated with regions where ocean currents and temperature gradients concentrate prey.

Role in the ecosystem

Swordfish helps explain how marine food webs function through its ecological role, habitat use, and connection to broader ecosystem change.
