This means it does not have bones, but instead has cartilage. It is one of over 600 recognized ray species. The red stingray can grow to 6 feet long and is known to weight up to 24 pounds. It has a pectoral fin disc that is diamond-shaped and is wider rather than longer. It gets its name from the coloration on its dorsal and ventral surfaces. Habitat & Range The red stingray is native to the northwestern Pacific Ocean and is found throughout coastal waters throughout Japan. They are commonly seen in sandy areas but also inhabit coral reefs and muddy flats. Unique Characteristics Their venomous tail spine is considered toxic to humans, but not fatal. Some ancient Japanese cultures have used the dried tail spine as a weapon because of its toxicity. Additionally, ancient dentists have used stingray venom to numb patients. Reproduction wild Facts Scientific The litter size of the red stingray is only between 1 and 10. Dasyatis akajei Name During courtship, males will follow females and bite at their pectoral fin disc using their pointed teeth. Then, once they gain a Weight 15 – 24 lbs solid grip they begin to mate. -

Seafood Watch® defines sustainable seafood as originating from sources, whether wild-caught or farmed, which can maintain or increase production in the long-term without jeopardizing the structure or function of affected ecosystems. Seafood Watch® makes its science-based recommendations available to the public in the form of regional pocket guides that can be downloaded from the Internet (seafoodwatch.org) or obtained from the Seafood Watch® program by emailing [email protected]. The program’s goals are to raise awareness of important ocean conservation issues and empower seafood consumers and businesses to make choices for healthy oceans. Each sustainability recommendation on the regional pocket guides is supported by a Seafood Report. Each report synthesizes and analyzes the most current ecological, fisheries and ecosystem science on a species, then evaluates this information against the program’s conservation ethic to arrive at a recommendation of “Best Choices,” “Good Alternatives,” or “Avoid.” The detailed evaluation methodology is available upon request. In producing the Seafood Reports, Seafood Watch® seeks out research published in academic, peer-reviewed journals whenever possible. -
Reproductive Biology of the Stingray Hypanus Marianae , an Endemic
ReproduCtive Biology of the stingray Hypanus marianae, an endemic species from Southwestern Tropical Atlantic Ocean Biologia Reprodutiva da raia Hypanus marianae, uma espécie endêmica do SudOeste do Oceano Atlântico Tropical Biología reproductiva de la raya Hypanus marianae, una especie endémica del suROeste del Océano Atlántico Tropical Ana Rita Onodera Palmeira Nunes1 Getulio Rincon1,2 Ricardo de Souza Rosa3 Jorge Luiz Silva Nunes1 Abstract The Brazilian Large-eyed stingray Hypanus marianae is the smallest species of the family Dasyatidae in Brazil. This study aims to provide data on the reproductive biology of this species captured in artisanal fisheries from Ceará State. A total of 299 individuals of H. marianae were recorded at monitoring landings and adult male to female sex ratio was significantly different (1:2.9), indicating a possible spatial segregation between males and females. The size range was from 13.0 to 36.2cm in disc width (DW). Females reached greater size and body mass (36.2cm DW and 1855g) than males (29.3cm DW and 915g). The reproductive system analyses were based on 81 preserved specimens. The DW50 parameter was estimated at 26.1cm DW for females, and 23.8cm DW for males. Only the left uterus is functional, and birth size was estimated at 13.0–14.0cm DW. Vitellogenesis occurred concurrently with a short gestation (shorter than 6 months) and uterine fecundity is only one embryo per reproductive cycle, which seems to be asynchronous. Keywords: maturity, fecundity, birth, embryos, Dasyatidae. Resumo A raia Mariquita Hypanus marianae é a menor espécie da família Dasyatidae no Brasil e este trabalho tem como objetivo reportar informações acerca da sua biologia reprodutiva a partir de capturas da pesca artesanal no estado do Ceará. -
Identification Guide to the Deep-Sea Cartilaginous Fishes Of
Identification guide to the deep–sea cartilaginous fishes of the Southeastern Atlantic Ocean FAO. 2015. Identification guide to the deep–sea cartilaginous fishes of the Southeastern Atlantic Ocean. FishFinder Programme, by Ebert, D.A. and Mostarda, E., Rome, Italy. Supervision: Merete Tandstad, Jessica Sanders (FAO, Rome) Technical editor: Edoardo Mostarda (FAO, Rome) Colour illustrations, cover and graphic design: Emanuela D’Antoni (FAO, Rome) This guide was prepared under the “FAO Deep–sea Fisheries Programme” thanks to a generous funding from the Government of Norway (Support to the implementation of the International Guidelines on the Management of Deep-Sea Fisheries in the High Seas project) for the purpose of assisting states, institutions, the fishing industry and RFMO/As in the implementation of FAO International Guidelines for the Management of Deep-sea Fisheries in the High Seas. It was developed in close collaboration with the FishFinder Programme of the Marine and Inland Fisheries Branch, Fisheries Department, Food and Agriculture Organization of the United Nations (FAO). The present guide covers the deep–sea Southeastern Atlantic Ocean and that portion of Southwestern Indian Ocean from 18°42’E to 30°00’E (FAO Fishing Area 47). It includes a selection of cartilaginous fish species of major, moderate and minor importance to fisheries as well as those of doubtful or potential use to fisheries. It also covers those little known species that may be of research, educational, and ecological importance. In this region, the deep–sea chondrichthyan fauna is currently represented by 50 shark, 20 batoid and 8 chimaera species. This guide includes full species accounts for 37 shark, 9 batoid and 4 chimaera species selected as being the more difficult to identify and/or commonly caught. -

A New Bathyal Shark Fauna from the Pleistocene Sediments of Fiumefreddo (Sicily, Italy)
A new bathyal shark fauna from the Pleistocene sediments of Fiumefreddo (Sicily, Italy) Stefano MARSILI Dipartimento di Scienze della Terra, Università di Pisa, Via S. Maria, 53, I-56126 Pisa (Italy) [email protected] and marsili76@@gmail.com Marsili S. 2007. — A new bathyal shark fauna from the Pleistocene sediments of Fiumefreddo (Sicily, Italy). Geodiversitas 29 (2) : 229-247. ABSTRACT A new shark fauna is described from the lower-middle Pleistocene marine sediments outcropping near the Fiumefreddo village, Southern Italy. Th e fos- sil assemblage mostly consists of teeth belonging to the bathydemersal and bathypelagic elasmobranch species Chlamydoselachus anguineus, Apristurus sp., Galeus cf. melastomus, Etmopterus sp., Centroscymnus cf. crepidater, Scymnodon cf. ringens, Centrophorus cf. granulosus and C. cf. squamosus, commonly recorded along the extant outer continental shelf and upper slope. From a bathymetrical KEY WORDS point of view, the present vertical distribution of the taxa collected allows an Elasmobranchii, estimate of a depth between 500 and 1000 m. Th e bathyal character of the sharks, bathyal, fauna provides new evidence of a highly diversifi ed and heterogeneous deep-sea teeth, Mediterranean Plio-Pleistocene marine fauna, in response to the climatic and paleobiogeography, hydrographical changes. Finally, the Fiumefreddo fauna provides new relevant Pleistocene, Sicily, data for the understanding of the processes involved in the evolution of the Italy. extant Mediterranean selachian fauna.
