Clouded angelshark
The Tarnished angel shark ( Squatina nebulosa ) is a soil- Hai, which is found in the Pacific coastal area of Japan, China, Korea and Taiwan.
Appearance and characteristics
The Tarnished Angel shark reaches a maximum length of up to 160 cm. As with other angel sharks of the hull is strongly flattened with very broad pectoral fins, making the animals more likely to act as long skates in shape. The pectoral fins, however, are clearly separated from the fuselage, while they go ansatzlos in the body in the most rays. They have two dorsal fins, and have no anal fin. The body has a eyebrow to blue- brown color with back scattered light and numerous dark spots. Eyespots may be present, but they will be inconspicuous with bright outer rings and dark core. The underside is white with dark border of the pectoral fins. Enlarged thorns in the head or on the back are not present.
The eyes are on top of the head with a concave surface between the eyes, the mouth is terminal, the external nasal openings are provided with short barbels. The injection holes are large. The number of sides, lying down gill openings is five. The nose flaps and the barbels are only slightly fringed or smooth margins.
Dissemination
The distribution area of cloudy in Engelhais is located in the coastal area of the Pacific in the area of Japan, China, Korea and Taiwan to a depth of 330 meters.
Way of life
Over the life of the cloudy in Engelhais are few data. Like other Engelhai he probably feeds primarily on small bony fishes, molluscs and crustaceans, which he captured as ambush predator lying on the floor. Like all angel sharks he is ovoviviparous - the eggs are hatched in the mother before the young are born alive.
Endangering
The International Union for Conservation of Nature ( IUCN) classifies this shark as endangered ( " Vulnerable "). The shark will be no direct fishing, but mainly caught as by-catch in the ground and trawling, which is carried out in its entire area of distribution; single individuals were detected in fish markets in northern Taiwan in China and Japan. The classification as an endangered species occurred in spite of the low knowledge of nature by comparison with other angel sharks, where population declines of more than 80% of areas were detected with high fishing pressure.
