What is "littlehead porgy"

The Littlehead porgy, Calamus proridens is an ocean-going species of gamefish of the family, Sparidae. It is only found in the western portion of the tropical Atlantic Ocean where they are often caught and used as food.

The Littlehead porgy was described in 1884 by the ichthyologists David Starr Jordan and Charles Henry Gilbert, who were both professors (Jordan later became president) of Stanford University.
