Habitat Istiophorus are saltwater fish. They like to live in the warmer south Atlantic and Pacific where the water is dramatically warmer. There are two main species of sailfish. The first more well known sailfish is the Atlantic sailfish. The other is the Indo-Pacific sailfish. Both types love to live in open water where the temperature range from 70 to 80 degrees Fahrenheit. They also tend to stay away from land in deep open water but keep close to surface.
Appearance Sailfish can appear as many colors ranging from a dark blue to a grey. These colors can be manipulated based on the situation the fish is in. It also has a white belly.

They then swim slowly with their dorsal fins up above the surface of the water. The males follow the females around usually by themselves or with a couple other males. A large female can release over 4 million eggs into the water. Sailfish grow very quickly at the beginning of their lives. Within a year one can grow up to 4 to 5 feet
