Pseudobatos Percellens
''Pseudobatos'' is a genus of fish in the Rhinobatidae family. Although its constituent species were previously assigned to ''Rhinobatos'', recent authors treat it as distinct. They are found in warmer coastal parts of the Americas, ranging from northern Chile to California (USA) on the Pacific side, and from northeastern Argentina to North Carolina (USA) on the Atlantic side. They are brownish or grayish above, and reach up to depending on the exact species. Species There are nine currently recognized species in this genus: * ''Pseudobatos buthi'' K.M. Rutledge, 2019 (spadenose guitarfish) * ''Pseudobatos glaucostigmus'' (D. S. Jordan & C. H. Gilbert, 1883) (speckled guitarfish) * ''Pseudobatos horkelii'' ( J. P.

Pseudobatos Productus
The shovelnose guitarfish (''Pseudobatos productus'') is a Batoidea, ray in the family Rhinobatidae. ''P. productus'' was first described by ichthyologist William Orville Ayres, William Orville Ayre in 1854 as ''Rhinobatos productus'', with the genus derived from the Greek word rhinos, meaning nose, and the Latin word batis, meaning ray. It was later placed in the genus ''Pseudobatos'' following reconsideration of many species placed in ''Rhinobatos''. As its common name suggests, this species possesses a pointed shovel-shaped snout and a body similar to that of a guitar with a larger head and long, slender body. The shovelnose is considered to be a primitively developed ray, with many features of both sharks and rays. The shovelnose guitarfish was first considered to be a shark because of its dorsal fins' shape. Fossils of ''P. productus'' ancestors have been recovered, dating back over 100 million years. Description The coloration of this species ranges from olive to sandy bro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudobatos Horkelii
The Brazilian guitarfish (''Pseudobatos horkelii'') is a species of fish in the family Rhinobatidae. It is endemic to Brazil, where its natural habitat is coastal waters on the continental shelf. This fish is viviparous and has a long gestation period, concluding with the birth of live pups in February. At this time the fish are subject to intense fishing activity but catches have been dwindling in recent years as a result of overfishing. Because so few breeding-size fish remain, the International Union for Conservation of Nature has assessed the fish's conservation status as being "critically endangered". Taxonomy The Brazilian guitarfish was first described as ''Rhinobatos horkelii'' by Müller & Henle in 1841. They named the new species in honour of the German botanist, Dr. Johann Horkel, Professor of Plant Physiology at the University of Berlin, who had sent them a specimen of the fish preserved in alcohol. Description This species can grow to a length of , but a more usua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
