Gymnuridae
The butterfly rays are the rays forming the genus ''Gymnura'' and the family Gymnuridae. They are found in warm oceans worldwide, and occasionally in estuaries. The body of butterfly rays is flattened and surrounded by an extremely broad disc formed by the pectoral fins, which merge in front of the head. They have a very short, thread-like, tail. They are up to in width. McEachran ''et al.'' place the butterfly rays in the subfamily Gymnurinae of the family Dasyatidae, but this article follows FishBase and ITIS in treating them as a family. Species There are currently 12 species in this genus (others are considered synonyms): * '' Gymnura altavela'' (Linnaeus, 1758) – Spiny butterfly ray * '' Gymnura australis'' ( E. P. Ramsay & Ogilby, 1886) – Australian butterfly ray * '' Gymnura crebripunctata'' ( W. K. H.

Smooth Butterfly Ray
The smooth butterfly ray (''Gymnura micrura'') is a species of cartilaginous fish in the family Gymnuridae. It is a member of the order Myliobatiformes, which contains 10 total families. Its natural habitats are shallow seas, subtidal aquatic beds, estuarine waters, and coastal saline lagoons. Its common name is derived from its compressed body, pectoral fins that are wider than their length, and overall diamond shape. Taxonomy Gymnura is derived from Greek roots and translates into 'naked tail'. They belong to a monophyletic group of Batoid fish. This group contains over 500 other elasmobranch fishes which includes electric rays, sawfishes, guitarfishes, skates, and stingrays. They are a part of Order Myliobatiformes and are characterized by their pectoral fins being widely expanded and fused to their heads. The family Gymnuridae contains 2 genera which encompass 12 different species. Description These are broad diamond-shaped rays with a short tail that has low dorsal and ...

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] |
Gymnura Altavela
The spiny butterfly ray or giant butterfly ray (''Gymnura altavela'') is a species of butterfly ray, family Gymnuridae, native to the shallow coastal waters of the Atlantic Ocean. A large ray that can measure over across, it may be distinguished from the sympatric smooth butterfly ray (''G. micrura'') by the spine at the base of its tail and by a small tentacular structure on the margin of each spiracle. Slow-reproducing and valued for its meat, in recent decades its population has experienced a decline of over 30%, and it has become Critically Endangered in certain parts of its range. Distribution and habitat This species has a patchy and discontinuous distribution in Atlantic tropical and warm-temperate waters. In the western Atlantic it is found from Massachusetts, United States to Buenos Aires Province, Argentina; it is rare in the Gulf of Mexico and common in the mouths of tidal creeks along the Virginia coast. In the eastern Atlantic, it is found from Portugal to Angola, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Batoidea
Batoidea is a superorder of cartilaginous fishes, commonly known as rays. They and their close relatives, the sharks, comprise the subclass Elasmobranchii. Rays are the largest group of cartilaginous fishes, with well over 600 species in 26 families. Rays are distinguished by their flattened bodies, enlarged pectoral fins that are fused to the head, and gill slits that are placed on their ventral surfaces. Anatomy Batoids are flat-bodied, and, like sharks, are cartilaginous fish, meaning they have a boneless skeleton made of a tough, elastic cartilage. Most batoids have five ventral slot-like body openings called gill slits that lead from the gills, but the Hexatrygonidae have six. Batoid gill slits lie under the pectoral fins on the underside, whereas a shark's are on the sides of the head. Most batoids have a flat, disk-like body, with the exception of the guitarfishes and sawfishes, while most sharks have a spindle-shaped body. Many species of batoid have developed their pe ...
