Field Guide for Sharks of the Genus Carcharhinus - Matthias Voigt Dietmar Weber Kartoniert (TB)

All known and relevant data and features to enable an identification of sharks of the genus Carcharhinus (BLAINVILLE 1816) are summarised and visualised in this book. The introduced species are difficult to separate for somebody who is not experienced in identifying sharks. An identification key is given to determine and to differentiate the species. For each species an extended list of characters is given including coloured figures to show the lateral and ventral view a detailed view of nostril and teeth and in some cases of juveniles and special characters. Further data on body size and a ppearance colouration tooth formula and shape numbers of vertebrae on other internal and external characters the geographical distribution preferred habitat and food spectrum are presented. In addition biological and reproductional data are included e. g. number of young per litter size at birth size at sexual maturity as well as behaviour and migrational patterns. Most of the previous works about Carcharhinus listed and discussed a maximum of 30 species. In contrast this field guide describes 33 species six species with special notes of the authors. Further a possible subdivision of the spinner shark C. brevipinna in an Atlantic and Pacific subspecies is briefly discussed. An almost unknown species C. acarenatus formerly considered a synonym of C. brachyurus is introduced. A very rare species C. leiodon which was hitherto recorded only once by GARRICK (1985) is included and controversially discussed. Another species in dispute Carcharhinus sp. A mentioned by COMPAGNO et al. (2005) as new member of the genus is comprised and discussed.
