Marine Mammals of Sri Lanka is the essential field guide to all of the marine mammals – whales, dolphins, porpoise and dugong - found in Sri Lankan and adjacent waters of the north Indian Ocean. The author's unique depth of experience and knowledge coupled with the artist's unrivaled paintings come together to produce a well laid out and practical field guide that will enable any observer to quickly identify any mammal they may encounter at sea.

Thirty species are illustrated to depict markings along with key characteristics and diagnostic information which can be used to quickly separate and identify each species at sea. Species information related to stranding identification is also included.

Each species is introduced with a currently accepted common name, followed by the scientific, and indigenous or translated Sinhala and Tamil common names. Also, status and distribution information is provided on the probability that the species is present in Sri Lankan waters as per geographic maritime province and depth.

Marine Mammals of Sri Lanka is in full colour and is printed and spiral bound in Sri Lanka with laminated art paper (waterproof) and pocket-sized (A5) for convenient use at sea.
