A follow up to the author's Reef Fishes and Corals, this guide covers a longer section of the coastline than the previous publication, introducing 262 reef fish species and containing a section by underwater photographer Valda Fraser on 48 species of the little-documented nudibranchs of the region. The guide facilitates species identification with concise text, illustration and colour photographs, including coverage of the different male and female, and adult and juvenile colour phases where relevant.
