Many people enjoy catching them as sporting fish in tropical areas. However, some species like the white marlin are endangered. This is because of overfishing in the oceans.

These fish have very special bodies for swimming. They have long, thin bodies and a spear-like snout. This snout is often called a bill.

Many marlins also have a long, stiff fin on their back. This fin can look like a crest. It can even look like a sail. This is why the name Istiophorus means "sail" in Greek.

Marlins can even change their color. They light up their stripes just before they attack their prey.

Scientists have studied these fish for a long time. George Kearsley Shaw first named the species Istiophorus platypterus in 1792.
