Myliobatidae
Myliobatidae is a family of rays, commonly known as eagle rays. They are characterized by their large, wing-like pectoral fins and a prominent, whip-like tail that often bears a venomous spine. Myliobatidae belong to the order Myliobatiformes, which includes other families like the devil rays and the manta rays.
Common Names
Myliobatidae are commonly referred to as eagle rays due to their large, wing-like pectoral fins that resemble the wings of an eagle in flight. Some species may also be known as cownose rays, spotted eagle rays, or simply eagle rays.
Characteristics
Myliobatidae share several distinct characteristics that distinguish them from other rays:
- Large, wing-like pectoral fins: These fins are responsible for their powerful swimming abilities. They can use their pectoral fins to fly through the water, gliding and maneuvering with incredible agility.
- Prominent, whip-like tail: The tail is typically long and thin, with a venomous spine located near its base. This spine is used for defense and can inflict painful injuries.
- Flattened body: Like all rays, Myliobatidae have a flattened body that allows them to live on or near the seabed.
- Spiracles: These openings on the top of the head allow for respiration while the ray is resting on the bottom. They are especially important when the ray is partially buried in the sand.
- Gill slits on the ventral surface: The gills are located on the underside of the body, which helps them stay close to the bottom.
Environment
Myliobatidae are found in tropical and subtropical waters around the world. They are typically found in coastal areas, estuaries, and open ocean environments. They prefer sandy bottoms and often inhabit areas with plenty of food, such as coral reefs and seagrass meadows.
Diet
Eagle rays are carnivores and feed on a variety of prey, including crustaceans, mollusks, fish, and even small sharks. They use their powerful jaws and sharp teeth to crush and tear their food.
