Abstract
This guide "The Marine Mammals of Tanzania & Zanzibar" was conceived in 2013 during the writing of "A Guide to the Large Mammals of Tanzania." At that time we identified 18 species of marine mammal (including 16 cetaceans) in Tanzanian waters, although it was clear the information available was scant, and there had been little work to pull together a definitive list based on comprehensive nationwide research. Since then, there have been taxonomic, nomenclature and conservation status changes, the Wildlife Conservation Society (WCS) carried out a six-week survey in 2015, and over the last five years more research has been carried out and new records added. Moreover, TD is compiling a complete annotates list to all Tanzania's mammals (> 430 spp.). Here we now list 28 species of marine mammal in Tanzania, although it is likely that more will be added with time and further study. Of the 26 cetaceans, six are baleen whales (Balaeonpteridae), and the remaining 20 are toothed whales, including one true sperm whale (Physeteridae), two sperm whales (Kogiidae), three beaked whales (Ziphiidae) and 14 dolphins (Delphinidae). In addition, there is one dugong (Dugongidae) and one eared seal (Otariidae), although the latter is a vagrant. The Guide is the first of its kind specifically targeting the United Republic of Tanzania, and by definition therefore, both the waters of mainland Tanzania and the archipelago of Zanzibar. In addition to general information on natural history, conservation, carbon capture and tourism, each species entry provides taxonomy, a description with maximum adult weights and lengths, habitat preference, distribution, the primary diet, the latest IUCN Red Listing, behaviour, and information pertinent to Tanzania. The illustrations are all original works, drawn exclusively by SM for conservation work by WCS in Tanzania. The aim of this guide is simple; to list and provide information and illustrations on all Tanzania's marine mammals and to illustrate more of the country's extraordinary biodiversity. Mostly, however, we hope this inspires Tanzanians and non-Tanzanians alike to enjoy, appreciate and help care for the nation's seas and seascapes, and the extraordinary wildlife within them.
