Unfortunately, the most critical threats to their existence tend to come from human hands: commercial and illegal fishing, oil spills, plastic pollution, unregulated tourism, the destruction of their natural habitats, and even passing ships and boats. (Experts aren’t entirely convinced that it’s an accurate gauge of animal self-awareness, though.)ĭue to their large size, giant manta rays have very few natural predators. Additionally, they’re among the few species capable of passing the mirror test, which researchers conduct to measure self-awareness in animals. These otherwise solitary animals have also demonstrated signs of social intelligence, as they’ve been observed to hunt in coordinated numbers. Species: Giant manta ray, Manta birostris, Remora Location: San Benedicto Island (Islas Revillagigedos), Baja California, Mexico Image ID. The smallest of the manta rays, the species Mobula diabolis of Australia, grows to no more than 60 cm (2 feet) across, but the Atlantic manta, or giant devil ray ( Manta birostris ), the largest of the family, may grow to more than 7 metres (23 feet) wide. However, the parts of giant manta rays’ brains associated with intelligence, vision and motor coordination appear to be enlarged. Of course, a big brain isn’t automatically a sign of high intelligence. It’s said that giant manta rays only give birth to a single pup every two to three years. While not much is known about the giant manta ray’s developmental stages, we’re aware of some specimens reaching up to 40 years of age. Key aggregation sites include: Southern Brazil, Ecuador, Thailand, Egypt, Southern Mozambique, and Mexico (Pacific Ocean). It possesses a pair of cephalic lobes, fleshy projections which help it draw more water and food into its mouth. (2008) Movements and site fidelity of the giant manta ray, Manta birostris, in the Komodo Marine Park, Indonesia. The giant manta (Manta birostris) is the most widely distributed manta ray and is found in all three of the world major oceans.This species is commonly encountered at offshore islands and seamounts.
It swims open-mouthed, using the gill plates in its mouth to filter krill and plankton. Like the blue whale, this massive fish is a filter-feeder.
