Photoidentification as a complementary tool to evaluate whale shark movements between different areas: the case of Nosy Be in Madagascar and the Gulf of Tadjoura in Djibouti
The whale shark Rhincodon typus, the world’s largest fish, is highly mobile, and is capable of migrating for thousands of kilometers each year. According to the IUCN Red List, areas where 500 or more individuals have been documented through either counts or model estimates include the Arabian Gulf a...
