Swordfish during early juvenile stage of life (up to 8 inches long), have "scales" that are markedly specialized and rather unique. They are in the form of bony tubercules or expanded compressed platelike bodies. These scales are rough, having spinous projections at the surface and they do not overlap one another as the scales in most fish do. With growth the scales disappear and the adult fish including those sold commercially have no scales

not in the sense of how more well known fish have scales like a tuna or bass. they do however have scales underneath a layer of skin and the scales cannot be removed without the skin coming off. so in short, they do have scales but not like other fish.
An angler is a person who fishes using a rod, reel, and bait to catch fish. Anglers can fish in rivers, lakes, or oceans for recreation or as a sport.
Angler fish live in the deep-sea environment where there is little to no light. They have specialized gills that allow them to extract dissolved oxygen from the water to breathe.
Angler fish primarily communicate through non-verbal cues, such as body language and bioluminescent signals. They use their light-producing organs to attract prey, signal potential mates, and communicate with other angler fish in the darkness of the deep sea. Their communication is often focused on hunting, reproduction, and maintaining social distance from other angler fish in their environment.
Angler fish eat small fish, crustaceans, and squid. They are known for their large mouths and sharp teeth that allow them to catch prey. Angler fish are typically apex predators and are not commonly preyed upon by other animals due to their size and adaptations for hunting in the deep-sea environment. However, some predators of angler fish may include larger fish, sharks, and marine mammals.
Yes, angler fish reproduce by external fertilization. The male angler fish is much smaller than the female and will attach itself to the female by biting onto her. The male eventually fuses with the female, sharing nutrients and providing sperm when she is ready to release eggs.
