Tetronarce
Tetronarce is a genus of electric rays in the family Torpedinidae, commonly known as torpedo rays. These rays are characterized by their ability to generate strong electric shocks to stun prey and defend themselves. They inhabit marine environments worldwide, with some species found in both shallow and deep waters.
Common Names
Members of the Tetronarce genus are often referred to as torpedo rays, electric rays, or numbfish.
Characteristics
Tetronarce species share several distinctive characteristics:
- Flattened bodies: Like other rays, Tetronarce have a flattened body shape with large pectoral fins that resemble wings.
- Electric organs: They possess specialized electric organs located on either side of their head, which can generate powerful electric shocks.
- Small eyes: Tetronarce have relatively small eyes, reflecting their reliance on electroreception for hunting and navigation.
- Gill slits: They have five pairs of gill slits on the ventral surface of their bodies.
Environments
Tetronarce species are found in a variety of marine environments, including:
- Continental shelves: Many species inhabit the shallow waters of continental shelves.
- Deep sea: Some species are found in deep ocean environments, down to depths of over 1,000 meters.
- Temperate and tropical waters: Tetronarce can be found in both temperate and tropical regions around the world.
