  2. http://en.wikipedia.org/wiki/Bowmouth_guitarfish#Taxonomy_and_phylogenyhttp://en.wikipedia.org/wiki/Bowmouth_guitarfish#Taxonomy_and_phylogeny Classification • Domain-Eukarya • Kingdom-Animalia • Phylum- Chordata • Class- Chondrichthyes • Order-Rhinobatiformes • Genus-Rhina • Species-ancylostoma Rhinaancylostoma

  3. Habitat • They have been found in tropical and subtropical coastal waters and off shore reefs. • They are in the Indo-Pacific near the Red sea and east Africa to Papua New Guinea, North to Japan, south of the central coast of New South Wales. • inhabits coastal water over a depth range of 3-90 m and usually on or near the bottom but can swim above it. Favors muddy habitats and rocky coral reefs. http://www.aquariumofpacific.org/onlinelearningcenter/species/bowmouth_guitarfish Where they have been found

  4. http://www.aquariumofpacific.org/onlinelearningcenter/species/bowmouth_guitarfishhttp://www.aquariumofpacific.org/onlinelearningcenter/species/bowmouth_guitarfish Niche • Most active at night and not territorial. • Feed mainly on bottom-dwelling crustaceans (crabs/shrimps) though they can eat mollusks/bony fishes. Locate prey though smell. Once it finds it prey it eases it into its mouth with short sharp thrusts while its teeth are used to crush their shells of their prey • Tiger sharks eat them so they have the “thorns” on its head to protect it. (includes butting) • Blue streak cleaner wrasses have a symbiotic relationship with Sharkray. • Males are mature at 4.9-5.9 ft. long (females can carry embryos that are 11-12 in long) • In captivity they can live up to 7 years wild is still unknown

(thorn like) • White on the buttom and scattered white spots over top of the shark and black marking above each pectoral fin. Younger the fish more vividly the colors are/bigger spots. • Bowmouth-mouth shape has wavy edges giving the appearance of a long bow • Guitarfish- shape of its body

  8. http://www.iucnredlist.org/details/summary/41848/0 They are vulnerable • They reproduce slowly • Cannot recover after threats they face (predators) • Large declines of the populations have been recorded over the years since the discovery of the species • The IUCN Red list labeled them vulnerable • TED’s (turtle Excluder Devices installed in some of the trawl nets have reduced their capture significantly.
