Mammals, birds, reptiles and amphibians, butterflies and moths, other insects, spiders, slugs and snails, trees and flowering plants from all round the Mediterranean are all included here, and each section is coded with a symbol for quick reference. From Cyprus in the east to the western end of the Mediterranean, the guide also covers species found in Portugal and the Algarve. While most Mediterranean habitats are low-lying, the range of the guide extends into the foothills of mountains. Shells and animals likely to be seen while snorkelling are also described and illustrated.
