The Incredibly Fast Sailfish

Daily Critter Facts, Fish Facts

Touted as being the fastest fish in the ocean, the sailfish, aka billfish, uses its speed and its long upper jaw to catch prey and hopefully avoid a sports fisherman. They also use their tall dorsal sail to aid in distracting prey in order to catch a meal. These bony fish can be found in all the oceans around the world, sans the colder Arctic and Antarctic waters. Due to their stable numbers and global populations, sailfish are listed as Least Concern by the IUCN.

First the Stats…

Scientific name: Istiophorus
Weight: Up to 220 lbs.
Length: Up to 10+ feet
Lifespan: Up to 15 years

Now on to the Facts!

1.) Sailfish prey on large bony fishes, crustaceans, and squid. They also work together, using their wonderful sails, to corral sardines and anchovies into tight fish balls in order to feast on more fish.

2.) They are preyed on by sharks, orcas, and mahi-mahi.

3.) There are 2 known species of sailfish: Indo-Pacific and Atlantic. But, since there are no mtDNA differences between the 2, most consider there being only 1 species.

4.) These fish are typically found in the epipelagic zone (the area from the surface to as deep as light penetrates).

5.) When caught by a fisherman, they tend to exhibit amazing breaches from the water.

But wait, there’s more on the sailfish!

6.) These fast growing fish reach sexual maturity in just 3 – 4 years.

7.) In the sailfish world, it’s the female who attracts the male. She does this by extending her dorsal fin, or sail, above the water.

Did you know…?
The sailfish may be able to swim at speeds of up to 68 mph!

8.) In what is called external fertilization, females release millions of eggs and the male then fertilizes said eggs.

9.) Females are larger than males.

10.) These amazing fish also use their long, pointed upper jaw to spear and tear at prey fish.

With over 50 years of critter experience to my credit and hundreds of zoology teaching hours to people around the world, I have amassed not only a continuing thirst for critter knowledge but a desire to teach others all I can about the majesty and wonder of our natural world. Critter Science is a culmination of such knowledge. I have hands on as well as book acquired intel on all kinds of critters. Whether they're on land, sea, or in the air. I will never say that I know everything about all animals. That's impossible, even for a savant. But, that being said, ask me any animal question and I'll answer it. If I don't know the answer, I'll get an answer for you!
