How to Identify Black Jack Fish

Video Transcript

The fish that we are going to identify now is the Black Jack. Black Jacks are fairly large, pelagic or open ocean dwelling fish but they can commonly be seen over reefs near deep water drop-offs. Black Jacks are usually dark gray in color and they have a steeply sloping forehead unlike most other jacks that are more bullet shaped. Black Jacks also have long anal and dorsal fins. Black Jacks are not very common in most of the waters around Florida, the Bahamas or the Caribbean, but can commonly be seen in some locations such as around Providence Isle and the Turks and Caicos Islands. Black Jacks are carnivores and can be observed rapidly swimming through schools of Silversides, feeding on the small fish as they dive through the school. Unlike Horse-Eye Jacks commonly seen in large schools, most Black Jacks that I have seen have been alone or in small groups of three or four fish. Black Jacks will often swim close by divers once or twice which some authorities speculate may be due to curiosity about the diver's bubbles. Snorkelers will not likely see this fish, since they only frequent reefs close to deep water drop-offs and don't venture into the shallows. Black Jackes are generally one to three feet long. That's the Black Jack.
