Bull Ray
''Aetomylaeus bovinus'', also known as the bull ray, is a species of large stingray of the family Myliobatidae found around the coasts of Europe and Africa. Biology and ecology The species is ovoviviparous and reach sexual maturity at 4 to 6 years old. With a low fecundity of three to four pups per litter and a long gestation of 6 to 12 months (depending on the geographical zone), this species have a very sensitive life history. Very little is known concerning the ecology and behavior of ''A. bovinus'', however it is part of the coastal marine megafauna, with a maximum length of 222 cm (87.4 in) and 116 kg (225.7 lbs), bull rays can be considered as giants of the shallow waters. Their maximum length and very narrow depth range of 0 to 30 m exposes them to various threats. Indeed, large-body, shallow-water species are at greatest risk of threats. Bull ray appears to be extremely rare throughout the Mediterranean region and its current population trend is highly sus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Round Ribbontail Ray
The round ribbontail ray (''Taeniurops meyeni'') is a species of stingray in the family Dasyatidae, found throughout the nearshore waters of the tropical Indo-Pacific, as well as off islands in the eastern Pacific. It is a bottom-dwelling inhabitant of lagoons, estuaries, and reefs, generally at a depth of . Reaching across, this large ray is characterized by a thick, rounded pectoral fin disc covered by small tubercles on top, and a relatively short tail bearing a deep ventral fin fold. In addition, it has a variable but distinctive light and dark mottled pattern on its upper surface, and a black tail. Generally nocturnal, the round ribbontail ray can be solitary or gregarious, and is an active predator of small, benthic molluscs, crustaceans, and bony fishes. It is aplacental viviparous, with the embryos sustained by yolk, and later histotroph ("uterine milk") secreted by the mother; up to seven pups are born at a time. Although not aggressive, if provoked the round ribbont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
