Roughies, flashlightfishes, and squirrelfishes live all over the world.
Squirrelfishes live in shallow, tropical reefs. Roughies live in dark ocean waters 1 mile (1,600 meters) deep. The fishes that live in shallow waters usually hide under a coral overhang, in a cave, or under another structure during the day.
Roughies, flashlightfishes, and squirrelfishes eat small fish and various invertebrates (in-VER-teh-brehts), which are animals without a backbone. The shallows dwellers feed mainly at night, although some feed on invertebrates passing through their daytime retreats.
Roughies, flashlightfishes, and squirrelfishes are important in the pet business. Orange roughy is fished commercially for food.
Roughies, flashlightfishes, and squirrelfishes are not threatened or endangered.

Perhaps the most notable characteristic of flashlightfishes, pineapplefishes, pineconefishes, and a few other fishes in this group is their ability to produce light and in some cases control it. The light is produced by glowing bacteria that live in pockets just below the skin of the fish. These fishes use the light to find and attract prey, or animals hunted and killed for food, during their nigh…
Physical characteristics: Splitfin flashlightfish are 4 to 12 inches (10 to 30 centimeters) long. These fish have large eyes with light-producing organs below them. They have two dorsal (DOOR-suhl) fins, which are the fins along the midline of the back. The rear dorsal fin is triangular and much larger than the front one. Geographic range: Splitfin flashlightfish live in the western part of the Pa…
Physical characteristics: Blackbar soldierfish grow to 10 inches (25 centimeters) in length. They are red and have large eyes, two dorsal fins, and a forked tail fin. They sport a brownish black, vertical bar behind the gill cover. Geographic range: Blackbar soldierfish live in the Gulf of Mexico and the eastern Atlantic Ocean from North Carolina to Brazil. Habitat: Blackbar soldierfish live in re…
