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 ...

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.

Hilgendorf's research on fossil snails from the Steinheim crater in the early 1860s became a palaeontological evidence for the theory of evolution published by Charles Darwin in 1859. Life and work Franz Hilgendorf was born on 5 December 1839 in Neudamm (Mark Brandenburg). Between 1851 and 1854 he went to a gymnasium in Königsberg (Neumark) and later to the Gymnasium ''Zum Grauen Kloster'' (Grey Monastery) in Berlin where he graduated in 1858.

Shark Genera
Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the rays. However, the term "shark" has also been used to refer to all extinct members of Chondrichthyes with a shark-like morphology, such as hybodonts and xenacanths. The oldest modern sharks are known from the Early Jurassic. They range in size from the small dwarf lanternshark (''Etmopterus perryi''), a deep sea species that is only in length, to the whale shark (''Rhincodon typus''), the largest fish in the world, which reaches approximately in length. Sharks are found in all seas and are common to depths up to . They generally do not live in freshwater, although there are a few known exceptions, such as the bull shark and the river shark, which can be found in both seawater and freshwat ...
