What do longheaded eagle rays look like?
The characteristics of the longheaded eagle ray (Aetobatus flagellum) are its long beak-like snout with a cephalic fin projecting up away from the head. It has a whip-like tail three times as long as its body length, with two to four venomous spines located just behind the pelvic fin.
Spiracles are located posterior to the bluish-black eyes, laterally on the head's dorsal side.
Longheaded eagle rays have a diamond-shaped disc with relatively large, narrowly triangular pectoral fins located posterior to the head. The dorsal fin is located between the pectoral fins and lacks a caudal fin.
The dorsal side of their disc is greenish-brown without spots. Their mouth is on the lower side of the disc, which is mainly white with green-brown spots along the perimeter of the disc. Females have a larger disc size than males.
They have a single row of broad, flat teeth in each jaw that combine to form upper and lower plates for crushing shelled prey.
How cute are they?
They are different-looking creatures with diamond-shaped bodies, long heads, and whip-like tails that make them look like flying birds underwater.
How do they communicate?
Like the spotted eagle ray, these species also communicate through special electrosensory organs known as the Ampullae of Lorenzini. They are primarily found in cartilaginous fish like sharks that increase the sensitivity to prey beneath the seafloor and allow the fish to detect changes in water temperature and pressure while they swim.
How big is a longheaded eagle ray?
The disc width of an adult male longheaded eagle ray range in size from 9.2 - 21.4 in (233 - 543 mm). At the same time, females have a disc width to a maximum of 9.6 - 22.8 in (243 - 579 mm).
