Marlins and swordfish might look similar at first with their large sizes and sword-like bills, making them easy to confuse. Yet, these two fish species have distinct traits that differentiate them from each other.
In the article, you will discover details like the main differences between marlin and swordfish, including physical differences, and examples of each in sentences.
The Main Difference between Marlin and Swordfish
Marlin vs. Swordfish: Overview
Understanding Marlin
Marlins are distinct fish characterized by their spear-like snout or bill and a pronounced dorsal fin that can resemble a crest. Our fellow marlins are equipped with a long upper jaw, used effectively to catch their prey, primarily consisting of squid and smaller fish. With bodies built for speed, marlins are some of the ocean’s most impressive predators.
Understanding Swordfish
When we look at swordfish, we’re examining a different class of ocean wanderers. These fish are known for their migratory patterns, traversing vast oceans and diving to significant depths as the seasons shift. Adult swordfish are identifiable by their round bodies and the loss of scales as they mature, differentiating them from the marlin with a dorsal fin shape that is more akin to a shark‘s.
Marlin vs. Swordfish: Physical Differences
To better understand the physical characteristics that set marlins and swordfish apart, we’ve compiled a table detailing their distinctive features. Let’s dive into those differences:
| Feature | Marlin | Swordfish |
|---|---|---|
| Bill | Sharply pointed, spear-like | Broad, flat, and shorter |
| Dorsal Fin | Prominent crest-like, elongated fin | Tall, sickle-shaped fin |
| Body Shape | More elongated | More round and robust |
| Scale Type | Dense, bony scales | Lose all scales as adults |
| Size | Large; can grow very big | Typically smaller than marlin |

Related Confused Animal Terms
Marlin vs. Sailfish
Marlins and sailfish share the family Istiophoridae, which can lead to confusion. We distinguish them by the sailfish’s smaller size and its characteristic dorsal fin, which is much larger and stretches down the length of the back, resembling a sail more than that of a marlin.
Swordfish vs. Sailfish
Although swordfish and sailfish have elongated bodies and long bills, they belong to different families—Xiphiidae and Istiophoridae, respectively. Swordfish are solitary with a rounder body, whereas sailfish prefer schools and showcase their sail-like dorsal fin.
Swordfish vs. Narwhal
Despite both possessing long, protruding features, swordfish and narwhals are distinct; a swordfish has a flat, sword-like bill, while a narwhal’s “horn” is actually a spiral tusk. Narwhals are Arctic cetaceans from the Monodontidae family, unrelated to swordfish.
Swordfish vs. Sawfish
Confusion arises here due to their similar names and long snouts, but a sawfish’s snout has teeth protruding from the sides, looking like a saw blade. Swordfish, on the other hand, have a smooth, pointed bill. Sawfish are rays from the Pristidae family, not fish closely related to swordfish.
