Last week Andy Allen and Reggie Begelton captured this video of a large manta ray swimming a mile west of the Sabine Jetties.
Manta rays are present in the Gulf of Mexico but sightings are rare and sightings with a mile of the beach are virtually unheard of in Texas.
According to Wikipedia, swimming behavior in mantas differs across habitats: when travelling over deep water, they swim at a constant rate in a straight line, while further inshore they usually bask or swim idly around. Mantas may travel alone or in groups of up to 50. They may associate with other fish species as well as sea birds and marine mammals. Mantas sometimes breach, leaping partially or entirely out of the water. Individuals in a group may make aerial jumps one after the other. These leaps come in three forms: forward leaps where the fish lands head first, similar jumps with a tail first re-entry or somersault. The reason for breaching is not known; possible explanations include mating rituals, birthing, communication, or the removal of parasites and remora.
“Manta rays have broad heads, triangular pectoral fins, and horn-shaped cephalic fins located on either side of their mouths. They have horizontally flattened bodies with eyes on the sides of their heads behind the cephalic fins, and gill slits on their ventral surfaces. Their tails lack skeletal support and are shorter than their disc-like bodies. The dorsal fins are small and at the base of the tail. The largest mantas can reach 1,350 kg (2,980 lb). In both species the width is approximately 2.2 times the length of the body; M. birostris reaches at least 7 m (23 ft) in width while M. alfredi reaches about 5.5 m (18 ft). Dorsally, mantas are typically black or dark in color with pale markings on their “shoulders”. Ventrally, they are usually white or pale with distinctive dark markings by which individual mantas can be recognized. All-black color morphs are known to exist. The skin is covered in mucus which protects it from infection.”
