Myliobatidae (Devil Rays)

Manta rays and devil rays are the common names for the members of the Mobulinae, a subfamily for the Myliobatidae (Eagle and Manta Rays) family. Similar to stingrays, eagle rays have broad, wing-like pectoral disc and have a very long tail. They are distinguished by their anteriorly extending rostral or cephalic fins that resemble a pair of horn.

Members of the Mobulinae are found in the temperate and tropical continental and insular seas worldwide. There are 2 genera and 11 species worldwide. They can be found from the seashore to a depth of at least 500 m, occurring on both soft and hard bottom around coral and rocky reefs, near kelp beds, and in estuaries, lagoons, and enclosed and open bay. These rays are strong and active swimmers, found near or on the bottom but often swimming well above it. Even the largest Devil Rays (Manta) are highly mobile and readily leap completely out of the water. All species are live-bearing. They have relatively weak jaws and small teeth that are not used for processing prey. Instead, they feed by filtering out planktonic animals and fishes that pass through their large mouths and are caught on the filter plates on their internal gill openings. The rostral fins aid in directing prey into the mouth.
