Distinguishing Features: Anatomy of Swordfish and Marlin

Let’s dive into the underwater world to see how swordfish and marlin differ. We’ll explore everything from their sleek bodies to where they live. First, we’ll look at their unique “swords” and bodies that make them top predators in the ocean.

Bill and Body Shape

Skin and Scale Variations

As they grow, swordfish lose their scales and teeth, unlike marlin. This unique change helps swordfish grow large and hunt diverse prey. Marlin keep their scales, which aids in their varied diet⁶.

Swordfish	Marlin
Maximum 177 inches (455 cm) in length⁵	Selective feeder on prey species⁶
Maximum 1,400 lbs (650 kg) in weight⁵	Feeds on a wider range of similarly sized prey⁶
Sexual maturity at 5-6 years of age⁵	Subtler meat taste often enjoyed raw⁶
Larger females, with specimens over 300 lbs (140 kg)⁵	Flamboyant dorsal fin for show in tropical waters⁵
