![]() ![]() Some of the most commonly reported species, according to our source, include: Several species of sharks have been known to feed on Manta Rays. Manta Rays are large and have been observed using evasive tactics when confronted by a shark, making them a less vulnerable target compared to smaller fish. The size and behavior of Manta Rays can also play a role in whether or not they are preyed upon by sharks. In some cases, pods of dolphins may also hunt Manta Rays. Manta Rays have few natural predators, but some of their potential predators include large marine animals such as whale sharks, tiger sharks, and killer whales. Nevertheless, populations of Manta Rays have declined significantly in recent years due to overfishing and other human activities, leading to increased conservation efforts to protect these magnificent creatures and their habitats. However, Manta Rays have few natural predators due to their large size and ability to defend themselves. They are also sometimes hunted by humans for their meat, fins, and other body parts.Īdditionally, humans sometimes hunt Manta Rays for their meat, fins, and other body parts, which are valued in some cultures for their use in traditional medicines and as food. Some Whales, like Killer Whales can also be added to this list. ![]() After a 12month gestation, a live pup is born, wrapped safely like a burrito and can immediately survive without the care of their mother.Manta rays are vulnerable to predation from several species of shark, including bull, tiger, and oceanic white-tip sharks, as well as seals and sea lions. Lasting for several days, the female will test her potential suitors by disrupting the train and checking which male is best at getting back into formation. When the female is ready to breed, a unique ‘courtship train’ begins, with the female followed by several males that mimic her every move. Manta rays can also create mental maps of their environment through visual cues and smell, hinting at advanced long-term memory.Īlthough they have few natural predators (the biggest being the killer whale and large sharks), female manta rays have a low fecundity, giving birth to one pup every two-three years and only reaching sexual maturity by the age of between eight and 10 years. With the largest brain to body size ratio of any living fish, studies reveal that the manta ray may recognise themselves in a mirror, indicating high cognitive function. When it comes to cold-blooded fish, the mantra ray is considered one of the most intelligent.

To satisfy their appetite, manta rays will use a range of different techniques including ‘ram-feeding’ (when a manta swims against the current with an open mouth), near-bottom feeding, looping, and cyclone feeding (where mantas follow each other in a circle with mouths open, creating a cyclone effect that traps food in a spiral). Imposing in size, but without a stinging barb and with a narrow row of minute teeth, the manta ray is a true gentle giant of the sea. Both manta ray species are filter feeders that cruise the ocean with their mouths open, filtering zooplankton and krill through the rows of tiny rakes that line their mouths called gill plates. With fingerprint-like identification in the form of unique spots on the underside of its belly, the manta ray has triangular, horn-like pectoral fins stemming from the front of its head, earning it the nickname “devil fish”. Reef manta rays are smaller at around three metres in width. With a large, flat, diamond-shaped body that can grow up to seven metres wide, the gigantic oceanic manta ray usually measures in at between four and four and a half metres between the tip of each of its wings.

The Spanish word ‘manta’ means blanket, shawl, or coat, and gliding through the ocean, these inquisitive animals take on the appearance of a floating, fluid piece of material, flapping in the watery current.Ī recent scientist discovery in 2008 revealed that instead of one species of manta ray, there are in fact two in existence – the reef manta ray ( Mobula alfredi) and the giant oceanic manta ray (Mobula birostris). Majestic and gentle, the manta ray is among the largest fish in the world. Gigantic oceanic manta rays average 4-4.5 metres, reef manta rays average 3 metres Filter feeder, eating zooplankton and krill ![]()
