The jack-knifefish or spotted drum (Equetus lanceolatus) is a small fish, typically between 6 and 9 inches, that can occasionally be found on coral reefs in the middle western Atlantic Ocean, in the Caribbean, the Gulf of Mexico, Florida and the Bahamas.
When jack-knifefish are young, they generally lives in rocks and coral hidden from predators. Generally they inhabit reef areas.
Jack-knifefish are carnivorous fish that feed on crabs,shrimp and small invertebrates.
This species of fish can live with other types of small fish, as it is not aggressive. Like other fishes of its family, it can produce "croaking" or "drumming" sounds.
Jack-knifefish are typically black and white or dark brown and white.
