- Although the flesh of the almaco jack is considered quality table fare, the species has been associated with ciguatera poisoning, a seldom fatal stomach irritation.
- The almaco jack is susceptible to tapeworm parasites in the caudal peduncle area, but the meat can be eaten safely if affected portions are cut away.
Jolthead porgy (Calamus)
The head of the jolthead porgy is distinctive from other porgies by its less rounded, sharp slope. Joltheads are silvery in color with yellowish brown areas on top and blue highlights above the eyes. They have very large eyes located at the top of the head. They are also larger than most of the porgy species. They have a long, spiny dorsal fin followed by a secondary dorsal fin and a long anal fin.
As an omnivorous fish, the jolthead porgy feeds on whatever is available in its habitat, including algae and smaller fish. They get their name from their habit of using the large head to bump and jolt clams and other mollusks out of their hiding places.
Jolthead porgies can be found in temperate waters in the Atlantic. Closer to the United States, they can be found off all Florida coasts and around the Bahamas.
Jolthead porgies prefer water above grass beds and around offshore reefs and patches. They are primarily bottom-dwellers and can be found in depths 20 to 30 feet.
- The world record jolthead porgy weighed 23 pounds, 4 ounces.
