Sharks and Rays - Elasmobranch
Guide of the World
by Ralf M Hennemann
This
305 page guide covers about 250 species of Sharks and Rays, all illustrated with
stunning photographs.
"Until just a few decades ago, very little was known about the
phylogenetically-old, but very successful group of sharks, rays and chimaeras
(ratfishes). Since then, a lot of information has become available on the 1,000
or so living species of cartilaginous fishes.
Naturally, the reef dwellers among them are better known than their deep sea
relatives. Hence, the focus of species selection for this unique identification
guide has been on those sharks and rays inhabiting shallow water. This makes it
an indispensible guide for divers and visitors to public aquaria.
In addition to including some little know species as well as fossil forms there
is also a discussion of relevant topics such as the utilization of cartilaginous
fishes by man, and their threatened extinction."
