Book: The waters around Australia are home to the greatest diversity of sharks and rays on Earth. Spookfish, numbfish, stingarees, fiddler rays and cookie-cutter sharks are just some of the 322 shark, ray and chimaerid species illustrated in the latest edition of Sharks and Rays of Australia. Australia’s sharks, rays and chimaerids — collectively known as Chondrichthyans — are just as intriguing as their names suggest. Their eclectic colours, shapes and patterns reflect environments ranging from remote estuaries to ocean depths. Their new descriptions, and their striking portraits by watercolourist Roger Swainston, will help to guide the identification and conservation of these diverse species. The first edition of Sharks and Rays of Australia was produced in 1994. Since then, 29 species have been discovered in Australian seas and more than 100 species have been named and formally described. As well as documenting these advances, the new edition includes updated species classifications and descriptions, distribution maps, line illustrations by Georgina Davis, family keys and outlines of Chondrichthyan biology and interactions with humans. The book catalogues a rich seam of Australia’s marine biodiversity, providing an indispensible compendium for scientists and a baseline reference for the fishing industry. Sharks and Rays of Australia is an essential reference for professional and recreational fishermen, divers, naturalists, students, fish and conservation biologists, and anyone interested in sharks and rays. Poster: Since 2007, the CSIRO’s Biogeography and Taxonomy team has described 80 new species of sharks, rays and chimaeras from Australian waters, in collaboration with numerous international experts. This represents more than a quarter of Australia’s, and about 7% of the world’s, shark and ray fauna. Full species accounts are available in the recently published Sharks and Rays of Australia, Second Edition by Peter Last and John Stevens. The collage of the 80 new species above highlights the very high diversity of sharks, rays and chimaeras found within the Australian region. The Biogeography and Taxonomy team at CSIRO Marine and Atmospheric Research in Hobart consists of: Peter Last, Daniel Gledhill, William White, John Pogonoski, Alastair Graham and Louise Conboy.
