Manta rays are large rays belonging to the genus Mobula. The larger species, M. birostris, reaches 7 m (23 ft) in width, while the smaller, M. alfredi, reaches 5.5 m (18 ft). Both have triangular pectoral fins, horn-shaped cephalic fins and large, forward-facing mouths. They are classified among the Myliobatiformes and are placed in the family Myliobatidae. They have the largest brains and brain to body ratio of all fish, and can pass the mirror test.
Bycatch, in the fishing industry, is a fish or other marine species that is caught unintentionally while fishing for specific species or sizes of wildlife. Bycatch is either the wrong species, the wrong sex, or is undersized or juveniles of the target species. The term "bycatch" is also sometimes used for untargeted catch in other forms of animal harvesting or collecting. Non-marine species that are caught but regarded as generally "undesirable" are referred to as rough fish or coarse fish.
The Mobulidae are a family of rays consisting mostly of large species living in the open ocean rather than on the sea bottom.
Mobula is a genus of rays in the family Mobulidae that is found worldwide in tropical and warm, temperate seas. Some authorities consider this to be a subfamily of the Myliobatidae. Their appearance is similar to that of manta rays, which are in the same family, and based on genetic and morphological evidence, the mantas belong in Mobula.
The Tethys Research Institute is a non-profit research organisation founded in 1986 to support marine conservation through science and public awareness and by participating in the international conservation process. Tethys' activities are mainly carried out in the Mediterranean Sea, although research programmes have been conducted also in the Black Sea, the North Atlantic Ocean, the Caribbean, the Red Sea and Antarctica. The results of these activities have been presented in scientific publications as well as in meetings, workshops and conferences.
The spinetail devil ray, also known as the spinetail mobula ray or Japanese mobula ray, is a species of pelagic marine fish which belongs to the family Mobulidae. It is found throughout the tropical and sub-tropical waters of the Indo-Pacific and eastern Atlantic Ocean.
Mobula munkiana, commonly known as the manta de monk, Munk's devil ray, pygmy devil ray, smoothtail mobula or Munk’s pygmy devil ray is a species of ray in the family Mobulidae. It is found in tropical parts of the eastern Pacific Ocean, ranging from the Gulf of California to Peru, as well as near offshore islands such as the Galapagos, Cocos, and Malpelo. Munk's devil ray was first described in 1987 by the Italian ecologist Giuseppe Notarbartolo di Sciara and named for his scientific mentor, Walter Munk.
The bentfin devil ray, also known as the lesser devil ray, smoothtail devil ray, smoothtail mobula or Thurston's devil ray, is a species of ray in the family Mobulidae. It is found worldwide in tropical, subtropical and warm temperate oceans, with records from Australia, Brazil, Chile, Costa Rica, Ecuador, Egypt, El Salvador, Eritrea, Guatemala, Honduras, India, Indonesia, Ivory Coast, Japan, Malaysia, Maldives, Mexico, Myanmar, Nicaragua, Oman, Pakistan, Peru, the Philippines, Saudi Arabia, Senegal, South Africa, Sri Lanka, Thailand, United Arab Emirates, United States (California), Uruguay, Vanuatu and throughout the central and western Pacific. It likely occurs in many other locations in tropical, subtropical and warm temperate oceans. It is found both offshore and near the coast.
The spiny butterfly ray or giant butterfly ray is a species of butterfly ray, family Gymnuridae, native to the shallow coastal waters of the Atlantic Ocean. A large ray that can measure over 2 m across, it may be distinguished from the sympatric smooth butterfly ray by the spine at the base of its tail and by a small tentacular structure on the margin of each spiracle. Slow-reproducing and valued for its meat, in recent decades its population has experienced a decline of over 30%, and it has become Critically Endangered in certain parts of its range.
Giuseppe Notarbartolo di Sciara is an Italian marine conservation ecologist who has bridged the worlds of marine science, conservation and policy.
The Memorandum of Understanding on the Conservation of Migratory Sharks is an international instrument for the conservation of migratory species of sharks. It was founded under the auspices of the Convention on the Conservation of Migratory Species of Wild Animals.
The giant oceanic manta ray, giant manta ray, or oceanic manta ray is a species of ray in the family Mobulidae and the largest type of ray in the world. It is circumglobal and is typically found in tropical and subtropical waters but can also be found in temperate waters. Until 2017, the species was classified in the genus Manta, along with the smaller reef manta ray. DNA testing revealed that both species are more closely related to rays of the genus Mobula than previously thought. As a result, the giant manta was renamed Mobula birostris to reflect the new classification.
The reef manta ray is a species of ray in the family Mobulidae, one of the largest rays in the world. Among generally recognized species, it is the second-largest species of ray, only surpassed by the giant oceanic manta ray.
Mobula kuhlii, the shortfin devil ray, is a species of ray in the family Mobulidae. It is endemic to the Indian Ocean and central-west Pacific Ocean. It ranges from South Africa, Mozambique, Tanzania and the Seychelles in the west to the Philippines and Indonesia in the east, and southward to the northern coast of Australia.
The common eagle ray or bullray is a species of fish in the family Myliobatidae. It inhabits the eastern Atlantic Ocean, the Mediterranean Sea and the south-western Indian Ocean.
The gill plate trade is the buying and selling of stingray gill plates for their use in traditional Chinese medicine. The gill plates are harvested from stingrays that are caught intentionally, or caught as bycatch. The plates are sold whole or in a powder form. A single kilogram of the gill plate can be sold for up to US$350, though the price varies by ray species.
Manta hynei is an extinct species of manta ray that was extant in the Pliocene. Its fossils have been found in North America, specifically North Carolina and Virginia. It was first described by Jim Bourdon in 1999, as a specimen dated to the Zanclean. The species is known from its distinctive fossilized teeth. Some authors have suggested, on the basis of tooth morphology, that this species should be classified in the genus Mobula instead.
The Marine Megafauna Foundation (MMF) is a marine biology research and conservation nonprofit known for discovering, researching, and protecting large marine animals including whale sharks, manta rays, sea turtles, whales, and dugongs.
