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 appearance 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.
