PALM BEACH DOLPHIN PROJECT FACT SHEET The Taras Oceanographic Foundation 5905 Stonewood Court - Jupiter, FL 33458 - (561-762-6473) [email protected] SPOTTED EAGLE RAY Aetobatus narinari CLASS: Chondrichthyes ORDER: Myliobatiformes FAMILY: Myliobatidae GENUS: Aetobatus SPECIES: narinari IDENTIFICATION: This is probably the easiest ray to identify. Broad angular disc, twice as wide as long, strongly concave posterior with angular tips. Dark brown to black with series of lighter spots/circles on the dorsal surface. Disc white ventrally. Large fleshy subrostral lobe. Dorsal fin near base of whip-like tail followed posterior by a venomous spine(s). SIZE AND AGE: Wingspan up to 10 feet (3 m) and up to 500 pounds (227 kg). Maximum total length (tip of snout to tip end of tail) is about 17 feet (5.2 m). Life expectancy ranges from 4 to 6 years. HABITAT: Commonly found in shallow inshore waters such as bays, and coral reefs, but also in depths of around 200 feet. FEEDING: Feeds mainly on bivalves but also eats shrimp, crabs, octopus, worms, whelks, and small fishes. REPRODUCTION: Aplacental viviparity (fertilized stingray eggs remain in the mother’s uterus, ingesting their yolk sacs. Once they have fully consumed their yolk sacs, the embryo is nourished by “uterine milk”), a lipid- and protein-rich fluid, secreted by the mother. Gestation period is estimated to be about one year. Up to four pups per litter. HUMAN FACTORS: Protected in Florida state waters. Often seen swimming near the water surface, occasionally leaping completely out of the water. Frequently forming large schools during the non-breeding season. Non-aggressive species of little danger to humans with the exception of their defensive venomous barb located near the base of the tail. Avoid handling or ex- ercise extreme caution.

Field Identification of Common Rays
Field Identification of Rays and Some Common Flatfishes of India Rekha J. Nair 6 Demersal Fisheries Division ORDER Myliobatiformes This suborder includes all of the Eagle Rays (Myliobatidae), Cownose Rays (Rhinopteridae) and the Mobulid Rays and includes about 40 species which are characterized by diamond shaped bodies and wing-like pectoral fins which they use to propel themselves through open water. Eagle Rays and Cownose Rays feed on the seabed, using their mouths to dig amongst the substrate in search of buried molluscs and crustaceans, while the mobulid rays lead a complete pelagic life. The order has 8 families under it. Family Dasyatidae – Whip tail sting rays Dorsal fin totally absent or indistinct if when present. Tail long and whip-like. Most species with at least 1 long venomous spine on tail, which can cause excruciating pain to humans. Dasyatis kuhlii Dasyatis zugei Training Manual on Species Identification Himantura gerrardi Hypolophus sephen Cow tail sting ray A high lower caudal finfold present which is 2 to 3 times depth of tail but not reaching tail tip; no large thorns; 1 or 2 long stings on tail, further behind tail base. Urogymnus asperrimus – Porcupine ray - Protected under Wild Life Act, 1972 Himantura uarnak – Honey comb sting ray Tail with alternating black and white bands, tip mostly pale; skin folds pale at base with dark outer margin, disc with blue dots.

Conservation Research on Spotted Eagle Rays in Florida and The
CONSERVATION RESEARCH ON SPOTTED EAGLE RAYS IN FLORIDA AND THE CARIBBEAN SEA Project Technical Report Submitted to the National Aquarium Conservation Center 26 January 2012 Kim Bassos-Hull Center for Marine Mammal and Sea Turtle Research Mote Marine Laboratory Sarasota, Florida Peter Hull, Dean Dougherty, and Krystan Wilkinson Division of Marine Operations Mote Marine Laboratory Sarasota, Florida Robert Hueter, John Morris and John Tyminski Center for Shark Research Mote Marine Laboratory Sarasota, Florida MOTE MARINE LABORATORY TECHNICAL REPORT NO. 1595 1 CONSERVATION SIGNIFICANCE The ultimate goal of the Spotted Eagle Ray Conservation Program is to establish a conservation plan for spotted eagle rays (Aetobatus narinari) in the Gulf of Mexico and Caribbean Sea through collaborative research and multinational relationships. The Spotted Eagle Ray Conservation Program was initiated in 2009 through a conservation partnership between Mote Marine Laboratory and the National Aquarium Conservation Center. This program provides an excellent opportunity to document long-term trends of a near-threatened elasmobranch species as well as provide training opportunities for researchers from other countries to learn sampling techniques and educational outreach possibilities. By engaging Mexican and Cuban research colleagues we hope to address questions of connectivity of spotted eagle ray populations throughout the Gulf of Mexico and Caribbean Sea, and do conservation capacity training and building in those other countries. Our future goals are to monitor fisheries, conduct live-sampling and tagging of individual rays in Mexico, Cuba, and other Gulf of Mexico and Caribbean countries, and further educational outreach by building on our initial years of research along the west coast of Florida.

Abstract: Cartilaginous fish are commonly recognized as key species in marine ecosystems for their fundamental ecological role as top predators. Nevertheless, effective management plans for cartilagi- nous fish are still missing, due to the lack of knowledge on their abundance, distribution or even life-history.

Field Guide for the Identification of Major Demersal Fishes of India
Field Guide for the identification of major demersal fishes of India Rekha J. Nair and P.U Zacharia Demersal Fisheries Division, CMFRI, Kochi -682018 [email protected] Capture fisheries and aquaculture supplied the world with 142 million tonnes of fish in 2008 (SOFIA, 2010) of which 79.9 mt was contributed by marine capture fisheries. In India, demersal fishery resources contributed to about 28 % of the total estimated landings of 3.16 million tonnes. The major demersal fish resources of the country are elasmobranchs, perches, croakers, catfishes, lizard fishes, silverbellies and flatfishes. Elasmobranchs: Fishery is constituted by sharks, rays and skates. They belong to Class Chondrichthys. ) 51 families, 178 genera, 937 species of extant elasmobranchs (ie around 403 sps of sharks & 534 sps of skates and rays) ) 28 species of sharks and rays are known from freshwater. ) In India - ) 110 species of elasmobranchs - 66 species of sharks, 4 saw fishes, 8 guitar fishes and 32 rays ) 34 species are commercially important. 1 Phylum: Chordata Class Elasmobranchii Order Carcharhiniformes 9 Family Carcharhinidae - (Requiem sharks) ) one of the largest and most important families of sharks ) eyes circular ) nictitating eyelids internal; spiracles usually absent. ∗ Genus : Carcharhinus Small to large sharks with round eyes, internal nictitating eyelids, usually no spiracles.
