FUN FACTS
The crevalle jack is prey for many surface feeding carnivores, such as the striped marlin and sea birds. Caranx hippos was named in 1766 from the French word “carangue” which means a Caribbean fish, and hippos which is Greek for “horse.” It is an important sport fish and is exploited throughout its range. It is the most common large jack caught off the west coast of Florida. They may even make a distinctive grunt or croak sound when they are caught!
