Migratory Sharks MoU
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 (CMS; also known as the Bonn Convention). Background Many sharks are apex predators and keystone species, meaning that they are at the top of their food chain and play a crucial role in maintaining the health of marine environments. Sharks whose members cyclically and predictably move large distances are considered migratory and many pelagic (open ocean) shark species fall into this category. The IUCN considers one-third of all shark species as threatened or near threatened. For migratory sharks the situation is worse, with almost 50% being considered as threatened and 27% being considered as near threatened. Relatively little is known about the behavior of migratory sharks; researchers have been surprised by data on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manila
Manila, officially the City of Manila, is the Capital of the Philippines, capital and second-most populous city of the Philippines after Quezon City, with a population of 1,846,513 people in 2020. Located on the eastern shore of Manila Bay on the island of Luzon, it is classified as a Cities of the Philippines#Independent cities, highly urbanized city. With , Manila is one of the world's List of cities proper by population density, most densely populated cities proper. Manila was the first chartered city in the country, designated bPhilippine Commission Act No. 183on July 31, 1901. It became autonomous with the passage of Republic Act No. 409, "The Revised Charter of the City of Manila", on June 18, 1949. Manila is considered to be part of the world's original set of global cities because its commercial networks were the first to extend across the Pacific Ocean and connect Asia with the Hispanic America, Spanish Americas through the Manila galleon, galleon trade.

Cetorhinus Maximus
The basking shark (''Cetorhinus maximus'') is the second-largest living shark and fish, after the whale shark. It is one of three plankton-eating shark species, along with the whale shark and megamouth shark. Typically, basking sharks reach in length, but large individuals have been known to grow more than long. It is usually greyish-brown, with mottled skin, with the inside of the mouth being white in colour. The caudal fin has a strong lateral keel and a crescent shape. Other common names include bone shark, elephant shark, sailfish, and sunfish. The basking shark is a cosmopolitan migratory species found in all the world's temperate oceans. A slow-moving filter feeder, its common name derives from its habit of feeding at the surface, appearing to be basking in the warmer water there. It has anatomical adaptations for filter-feeding, such as a greatly enlarged mouth and highly developed gill rakers. Its snout is conical, and the gill slits extend around the top and bott ...

Mobula Tarapacana
The Chilean devil ray (''Mobula tarapacana''), also known as the box ray, greater Guinean mobula, sicklefin devil ray or the spiny mobula, is a species of ray in the family Mobulidae. It is often observed worldwide, basking just below the surface in tropical, subtropical and warm temperate oceans, mainly offshore, and occasionally appearing near the coast. It can reach a disc width of up to . Originally believed to be surface dwellers, ''Mobula tarapacana'' have been discovered to feed at depths of up to during deep dives; they are among the deepest-diving ocean animals. Their dives often follow a stepwise pattern, in which the ray dives deeply, then works its way back up by repeatedly "levelling up" for a bit and then moving higher. Sonar observations suggest that rays level up where there are denser layers of prey, suggesting that this is a foraging behavior. Rays display two distinct deep-dive patterns. The stepwise dive pattern, which is usually only performed once every ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mobula Rochebrunei
The lesser devil ray (''Mobula hypostoma'') is a species of devil ray in the family Mobulidae. Habitat These rays live in shallow, warm waters and can be found in shoals of up to 40 individuals, although more often ranging between 2 and 10. They occur along the coasts of the western Atlantic, from North Carolina to northern Argentina Argentina, officially the Argentine Republic, is a country in the southern half of South America. It covers an area of , making it the List of South American countries by area, second-largest country in South America after Brazil, the fourt ....

Mobula Munkiana
''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 Batoidea, ray in the family Mobulidae. They are commonly mistaken for their close relatives, ''M. thurstoni'' (bentfin devil ray) and ''M. mobular'' (giant devil ray). Although they are the smallest of the species in genus ''Mobula'', they make up for their size with their incredible speed and agility. These characteristics are a likely explanation for their lack of natural predators, although they have been known to be hunted by orcas and are often fished by humans. One of the defining characteristics of this group are their acrobatic performances that are conducted while jumping in the air in schools of thousands. It is thought that these spectacles are a functional part of their lifestyle, including kickstarting mating rituals. The species was first described in 1987 after the Italian ecologist Giuseppe Notarbartolo di Sciar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mobula Mobular
The devil fish or giant devil ray (''Mobula mobular'') is a species of ray in the family Mobulidae. It is currently listed as endangered, mostly due to bycatch mortality in unrelated fisheries. Description The devil fish is larger than its close relative the lesser devil ray. It grows to a length of disk , making it one of the largest rays. It possesses a spiny tail. The devil fish is the third largest species in the genus ''Mobula'', after the oceanic and reef manta rays. It is the only mobulid species that lives in the Mediterranean Sea. The species has been observed to have a maximum recorded length of disk width of 5.2 meters (roughly 17 feet). However, those data are unreliable and are allegedly misunderstood as giant oceanic manta rays that have strayed into the Mediterranean. It is also considered to be the only devil fish with a tail spine. Distribution and habitat The devil fish is most common in the Mediterranean Sea. It is also found in the Eastern Atlantic Ocea ...

Mobula Kuhlii
''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. Description The shortfin devil ray is a small eagle ray growing to a maximum width of and a weight of . It is flattened horizontally with a wide central disc and the head is short with small cephalic fins. The large pectoral fins have curved tips and the dorsal fin has a white tip.

Mobula Japanica
The spinetail mobula (''Mobula japanica''), also known as the spinetail devil ray or Japanese mobula ray, is a species of pelagic marine fish which belongs to the family Mobulidae. The spinetail mobula gets its name due to its devil like appearance from the "horns" on its head and the unique spines on its tail. Generally, these rays love to be mobile and show off their aerial acrobatics. ''M. japanica'' can be found throughout the tropical and sub-tropical waters of the Indo-Pacific and eastern Atlantic Ocean. Taxonomy ''Mobula japanica'' falls under the order Myliobatiformes and family Mobulidae. The Mobulidae family is a family of rays, manta rays and devilfish specifically, consisting of 11 species. The IUCN suggests that the species should be considered conspecific with the devil fish (''Mobula mobular'') Due to its low population growth and low reproduction rates, there isn't much variability or "branch off" species from ''M. japanica''. Recently, a study found no genetic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
