Proscylliidae
The finback catsharks are a small family, the Proscylliidae, of ground sharks. They can be found in warm seas worldwide and are often the most numerous and common shark in tropical regions. They are generally less than 1 m in length, and are slow-moving predators that feed on bony fish and small invertebrates. Although some bear live young, the majority lay eggs with almost fully developed young; these egg cases, known as "mermaid's purses", are unique in appearance to each species. Taxonomy Genus ''Proscyllium'' * Graceful catshark (''Proscyllium habereri'') was first discovered by Hildendorf in 1901. * ''Proscyllium venustum'' is found in temperate regions. It is distributed along the Northwest Pacific, primarily Japan. These sharks are oviparous; they lay eggs in pairs in which the embryos feed solely on yolk. This species is considered harmless to humans. * Magnificent catshark (''Proscyllium magnificum'') A newly discovered species within the family Proscyllidae, it has ...

Carcharhiniformes
Carcharhiniformes , the ground sharks, are the largest order of sharks, with over 270 species. They include a number of common types, such as catsharks, swellsharks, and the sandbar shark. Members of this order are characterized by the presence of a nictitating membrane over the eye, two dorsal fins, an anal fin, and five gill slits. The families in the order Carcharhiniformes are expected to be revised; recent DNA studies show that some of the conventional groups are not monophyletic. The oldest members of the order appeared during the Middle-Late Jurassic, which have teeth and bodyforms that are morphologically similar to living catsharks. Carchariniformes first underwent major diversification during the Late Cretaceous, initially as small-sized forms, before radiating into medium and large body sizes during the Cenozoic. Families According to FishBase, the nine families of ground sharks are: [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Magnificent Catshark
The magnificent catshark or clown catshark (''Proscyllium magnificum'') is a species of finback catshark, belonging to the family Proscylliidae, known only from five specimens collected in the northern Andaman Sea near the edge of the Myanmar continental shelf. Its common names refer to its distinctive, elaborate color pattern of small and large dark spots, which include "clown faces" beneath each dorsal fin. Reaching in length, this species has a very slender body with a short, flattened head and a large lobe of skin in front of each nostril. The first dorsal fin is placed behind the pectoral fins but ahead of the pelvic fins. Taxonomy The first specimens of the magnificent catshark were caught during a 1989 joint Thai- Burmese survey of the Myanmar continental shelf, and described by Peter Last and Vararin Vongpanich in a 2004 issue of the ''Phuket Marine Biological Center Research Bulletin''. Its specific epithet is derived from the Latin ''magnificus'' ("noble" or "sple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
