A New Stingray from South Africa
Nature Vol. 289 22 January 1981 221 A new stingray from South Africa from Alwyne Wheeler ICHTHYOLOGISTS are accustomed to the regular description of previously un recognized species of fishes, which if not a daily event at least happens so frequently as not to cause great comment. Previously undescribed genera are like wise not infrequently published, but higher categories are increasingly less common. The discovery of a new stingray, which is so different from all known rays as to require both a new family and a new suborder to accommodate its distinctive characters, is therefore a remarkable event. A recent paper by P.e. Heemstra and M.M. Smith (Ichthyological Bulletin oj the J. L.B. Smith Institute of Ichthyology 43, I; 1980) describes this most striking ray as Hexatrygon bickelli and discusses its differences from other batoid fishes. Surprisingly, this remarkable fish was not the result of some organized deep-sea fishing programme, but was found lying on the beach at Port Elizabeth. It was fresh but had suffered some loss of skin by sand abrasion on the beach, and the margins of its fins appeared desiccated in places. The way it was discovered leaves a tantalising question as to its normal habitat, but Heemstra and Smith suggest that it may live in moderately deep water of 400-1,000m. This suggestion is Ventral view of Hexatrygon bickelli supported by its general appearance (small eyes, thin black dorsal skin, f1acid an acellular jelly, while the underside is chimaeroids Rhinochimaera and snout) and the chemistry of its liver-oil. richly supplied with well developed Harriota, and there can be little doubt The classification of Hexatrygon ampullae of Lorenzini. -

Each 28 cell has two major dendrites thought to receive segregated streams of sensory input: the lateral 29 dendrite receives mechanosensory input while the ventral dendrite receives visual input. -

Electrosensory Pore Distribution and Feeding in the Basking Shark Cetorhinus Maximus (Lamniformes: Cetorhinidae)
Vol. 12: 33–36, 2011 AQUATIC BIOLOGY Published online March 3 doi: 10.3354/ab00328 Aquat Biol NOTE Electrosensory pore distribution and feeding in the basking shark Cetorhinus maximus (Lamniformes: Cetorhinidae) Ryan M. Kempster*, Shaun P. Collin The UWA Oceans Institute and the School of Animal Biology, The University of Western Australia, 35 Stirling Highway, Crawley, Western Australia 6009, Australia ABSTRACT: The basking shark Cetorhinus maximus is the second largest fish in the world, attaining lengths of up to 10 m. Very little is known of its sensory biology, particularly in relation to its feeding behaviour. We describe the abundance and distribution of ampullary pores over the head and pro- pose that both the spacing and orientation of electrosensory pores enables C. maximus to use passive electroreception to track the diel vertical migrations of zooplankton that enable the shark to meet the energetic costs of ram filter feeding.

Flying Fish! by Guy Belleranti
Name: __________________________________ It's Not a Bird... Not a Plane... It's a Flying Fish! by Guy Belleranti Did you know there is group of fish known as flying fish? Flying fish are found in all the major oceans. There are over 40 known species. They are most common in warmer tropical and sub-tropical areas. Of course, a flying fish doesn't actually fly like a birds does. But it can jump out of the water and glide through the air. How does it do this? First, the flying fish swims near the water's surface. Holding its side (pectoral) fins close to its body, the fish's tail (called the caudal fin) propels the Night fishermen use lights to help them catch torpedo-shaped fish at speeds of 35 to 40 miles flying fish. The fishermen know that flying fish are per hour. The tail is forked, with the lower lobe attracted to the lights so this is a great way to lure longer than the upper lobe. This lower lobe acts the fish to their boats and canoes. like an outboard motor. Angling upward, the fish bursts above the water's surface and into the air. Near Catalina Island, off the coast of California, Then the fish spreads its extra large pectoral fins night tour boats also use lights. But this time the and glides for hundreds of feet.

Lake Magadi Tilapia (Alcolapia grahami) Ecological Risk Screening Summary U.S. Fish & Wildlife Service, March 2015 Revised, August 2017, October 2017 Web Version, 8/21/2018 1 Native Range and Status in the United States Native Range From Bayona and Akinyi (2006): “The natural range of this species is restricted to a single location: Lake Magadi [Kenya].” Status in the United States No records of Alcolapia grahami in the wild or in trade in the United States were found. The Florida Fish and Wildlife Conservation Commission has listed the tilapia Alcolapia grahami as a prohibited species. Prohibited nonnative species (FFWCC 2018), “are considered to be dangerous to the ecology and/or the health and welfare of the people of Florida. These species are not allowed to be personally possessed or used for commercial activities.” Means of Introductions in the United States No records of Alcolapia grahami in the United States were found. 1 Remarks From Bayona and Akinyi (2006): “Vulnerable D2 ver 3.1” Various sources use Alcolapia grahami (Eschmeyer et al. 2017) or Oreochromis grahami (ITIS 2017) as the accepted name for this species. Information searches were conducted under both names to ensure completeness of the data gathered. 2 Biology and Ecology Taxonomic Hierarchy and Taxonomic Standing According to Eschmeyer et al. (2017), Alcolapia grahami (Boulenger 1912) is the current valid name for this species. It was originally described as Tilapia grahami; it has also been known as Oreoghromis grahami, and as a synonym, but valid subspecies, of -
