Dasyatis Laevigata
The Yantai stingray, ''Hemitrygon laevigata'' (often misspelled ''laevigatus''), is a little-known species of stingray in the family Dasyatidae, inhabiting shallow waters in the northwestern Pacific Ocean off the coasts of China and Japan. Measuring no more than across, this species is characterized by its diamond-shaped pectoral fin disc wider than long, completely smooth skin, dorsal coloration of dark irregular spots on a yellowish gray-brown background, and ventral coloration of more spots on a white background with yellowish margins. One of the three most common stingrays sold for food in China, the slow-reproducing Yantai stingray faces possible overfishing and habitat degradation, and its numbers appear to be declining. The International Union for Conservation of Nature (IUCN) has assessed it as vulnerable. Taxonomy The Yantai stingray was described by Yuanting Chu in his 1960 ''Cartilaginous Fishes of China'', based on specimens obtained from the Shanghai Fish Market, Do ...

Gymnura Poecilura
The longtail butterfly ray (''Gymnura poecilura'') is a species of butterfly ray, family Gymnuridae, native to the Indo-Pacific from the Red Sea to southern Japan and western Indonesia. Growing up to across, this ray has a lozenge-shaped pectoral fin disc about twice as wide as long, colored brown to gray above with many small, light spots. The spiracles behind its eyes have smooth rims. This species can be identified by its tail, which is about as long as the snout-to-vent distance, lacks fins, and bears nine to twelve each of alternating black and white bands. Bottom-dwelling in nature, the longtail butterfly ray frequents sandy or muddy habitats in coastal waters shallower than . Its diet consists of bony fishes, molluscs, and crustaceans. This species gives birth to live young; the developing embryos are nourished first by yolk and later by histotroph ("uterine milk") supplied by its mother. There is no defined breeding season, and females bear litters of up to seven pups. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Discopyge Tschudii
The apron ray (''Discopyge tschudii'') is a small electric ray in the numbfish family, Narcinidae, known for being able to generate electric shocks for defense. It is one of two species in the genus ''Discopyge''. Distribution and habitat The apron ray is a coldwater marine species found off South America south of the 33°S parallel. It occurs in the southwest Atlantic Ocean along the coasts of Uruguay and Argentina, with small numbers entering southern Brazil in the winter, and in the southeast Pacific Ocean along the coasts of Chile and Peru.

It lives on the continental shelf and prefers sandy substrate. Description In form, the apron ray resembles the genus '' Narcine'' in having a circular pectoral fin disc, two dorsal fins, and a stout tail with lateral folds. Its distinguishing feature ...

Dipturus Nidarosiensis
The Norwegian skate (''Dipturus nidarosiensis''), or black skate, is a species of skate found at depths of to over in the East Atlantic region. Initially its range was believed to be restricted to the Norwegian Sea and North Sea to the Bay of Biscay. It is occasionally encountered off the western coast of Ireland, and historically has been found near Rockall and in the Norwegian Deep, though recent surveys have not identified the species there. The species has frequently been confused with other skates, and since the late 1980s it has been confirmed to occur more widely, ranging from Iceland to Morocco, as well as off South Africa and in the Mediterranean Sea.Guide of Mediterranean Skates and Rays (''Dipturus nidarosiensis'').
