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. Diet Length 4 – 6 ft Crustaceans are the largest part of the red stingray diet. They Lifespan 15 – 25 years also eat smaller bony fish from time to time. Other Stingrays, Closest Predators, Threats & Conservation Manta Rays & Relatives Sharks Due to Japanese fisheries and a slow reproduction rate their population has declined from 20,000 in the 1950s to 5,300 in 2004.

  • Stingray Bay: Media Kit
    STINGRAY BAY: MEDIA KIT Stingray Bay has been the talk of the town! What is it? Columbus Zoo and Aquarium guests and members will now have the opportunity to see stingrays up close and to touch these majestic creatures! The Stingray Bay experience will encourage visitors to interact with the Zoo’s brand new school of stingrays by watching these beautiful animals “fly” through the water and dipping their hands in the water to come in contact with them. Where is located? Located in Jungle Jack’s Landing near Zoombezi Bay, Stingray Bay will feature an 18,000-gallon saltwater pool for stingrays to call home. Staff and volunteers will monitor the pool, inform guests about the best ways to touch the animals and answer questions when the exhibit opens daily at 10 a.m. What types of stingrays call Stingray Bay home? Dozens of cownose and southern stingrays will glide though the waters of Stingray Bay. Educational interpreters will explain the role of these stingrays in the environment. Stingrays are typically bottom feeders with molar-like teeth used to crush the shells of their prey such as crustaceans, mollusks, and other invertebrates. I’m excited to touch the stingrays, but is it safe? Absolutely! The rays barbs have been carefully trimmed off their whip-like tails. The painless procedure is similar to cutting human fingernails. Safe for all ages, the landscaped pool features a waterfall and a wide ledge for toddlers to lean against when touching the rays. This sounds cool! How much does it cost? Admission to Stingray Bay is free for Columbus Zoo and Aquarium Gold Members and discounted for Members.

Malaysia National Plan of Action for the Conservation and Management of Shark (Plan 2), Ministry of Agriculture and Agro- based Industry Malaysia, Putrajaya, Malaysia. 50pp SUMMARY Malaysia has been very supportive of the International Plan of Action for Sharks (IPOA-SHARKS) developed by FAO that is to be implemented voluntarily by countries concerned. This led to the development of Malaysia’s own National Plan of Action for the Conservation and Management of Shark or NPOA-Shark (Plan 1) in 2006. The successful development of Malaysia’s second National Plan of Action for the Conservation and Management of Shark (Plan 2) is a manifestation of her renewed commitment to the continuous improvement of shark conservation and management measures in Malaysia.

Fowler, Tim M. Reed and Frances A. Dipper Occasional Paper of the IUCN Species Survival Commission No. 25 IUCN The World Conservation Union Donors to the SSC Conservation Communications Programme and Elasmobranch Biodiversity, Conservation and Management: Proceedings of the International Seminar and Workshop, Sabah, Malaysia, July 1997 The IUCN/Species Survival Commission is committed to communicate important species conservation information to natural resource managers, decision-makers and others whose actions affect the conservation of biodiversity. The SSC's Action Plans, Occasional Papers, newsletter Species and other publications are supported by a wide variety of generous donors including: The Sultanate of Oman established the Peter Scott IUCN/SSC Action Plan Fund in 1990. The Fund supports Action Plan development and implementation. To date, more than 80 grants have been made from the Fund to SSC Specialist Groups. The SSC is grateful to the Sultanate of Oman for its confidence in and support for species conservation worldwide. The Council of Agriculture (COA), Taiwan has awarded major grants to the SSC's Wildlife Trade Programme and Conservation Communications Programme. This support has enabled SSC to continue its valuable technical advisory service to the Parties to CITES as well as to the larger global conservation community. Among other responsibilities, the COA is in charge of matters concerning the designation and management of nature reserves, conservation of wildlife and their habitats, conservation of natural landscapes, coordination of law enforcement efforts as well as promotion of conservation education, research and international cooperation.

  • Study on Some Properties of Acid-Soluble Collagens Isolated from Fish Skin and Bones of Rainbow Trout (Onchorhynchus Mykiss)
    International Food Research Journal 19(1): 251-257 (2012) Study on some properties of acid-soluble collagens isolated from fish skin and bones of rainbow trout (Onchorhynchus mykiss) 1Shahiri Tabarestani, H., 2 Maghsoudlou, Y., 3*Motamedzadegan, A., 2Sadeghi Mahoonak, A. R. and 4Rostamzad, H. 1Department of Food Science and Technology, Ferdowsi University of Mashhad, Mashhad, Iran 2 Food Engine Department, Natural Resources and Agricultural Sciences University, Gorgan, Iran 3Department of Food Science, Sari Agricultural Sciences and Natural Resources University, Iran. PoBox 578 4Fisheries Department, Natural Resources and Agricultural Sciences Universities, Gorgan, Iran Abstract: To make more effective use of fish–byproduct resources, acid-soluble collagen (ASC) was isolated from the skin and bones of rainbow trout (Onchorhynchus mykiss) with yields of 9.448% and 1.122% on a wet weight basis, respectively. Based on their electrophoretic pattern, both collagens were classified as type І with slightly different amino acid compositions and low imino acid content. From the result, both collagens were rich in inter- and intra-molecular cross-linked components, ß and γ components with bone collagen having more band intensity. Similar changes in viscosity of collagens from the skin and bone of rainbow trout were observed. Collagens from the skin and bones had minimum solubility at pH 9 and 7, respectively. No changes in solubility were observed in the presence of NaCl up to 3% (w/v). However, a sharp decrease in solubility was found above 3% NaCl. Keywords: Collagen, acid-soluble collagen rainbow trout, Onchorhynchus mykiss, fish skins, fish bones Introduction So far, skin and bone collagen from several fish species have been isolated and characterized Collagens are generally extracellular structural (Kimura et al., 1991; Ciarlo et al., 1997; Nagai and proteins involved in formation of connective tissue Suzuki, 2000a, 2000b; Yata et al., 2001; Nagai et structure and are known to occur in genetically distinct al., 2002; Sadowska et al., 2003).

Associate editor: Yoko Satta Abstract In the Metazoa, globin proteins display an underlying unity in tertiary structure that belies an extraordinary diversity in primary structures, biochemical properties, and physiological functions. Phylogenetic reconstructions can reveal which of these functions represent novel, lineage-specific innovations, and which represent ancestral functions that are shared with homologous globin proteins in other eukaryotes and even prokaryotes. To date, our understanding of globin diversity in deuterostomes has been hindered by a dearth of genomic sequence data from the Ambulacraria (echinoderms þ hemichordates), the sister group of chordates, and the phylum Xenacoelomorpha, which includes xenoturbellids, acoelomorphs, and nemertodermatids. Here, we report the results of a phylogenetic and comparative genomic analysis of the globin gene repertoire of deuterostomes.
