Besides their sheer size, whale sharks are instantly recognisable by their intricate pattern of spots and stripes. Thought to serve as a form of camouflage, these markings are also unique to each individual — making them as useful for identification as a human fingerprint.

Whale sharks and remoras? The ocean’s odd couple. Remoras are large, slender suckerfish, built for a life attached to something bigger — and in latching onto the ocean’s largest fish, they gain shelter and protection. But that’s not all; they also benefit from a constant food supply, picking up plankton as the whale shark filter-feeds, and clearing the shark of parasites and dead skin. This service to the shark is invaluable, the basis of their symbiotic relationship.

While whale sharks are commonly seen filter-feeding by swimming forward with their mouths agape, ram feeding isn’t their only technique. They are also capable of suction feeding — remaining stationary within a productive prey patch and rhythmically pumping plankton-rich water across their gills.

Ecotourism draws people into the world of the creatures they encounter — and those encounters call for responsible, ethical best practice. In Madagascar, where whale shark tourism is booming, SOSF project leader Stella Diamant has designed a code of conduct to improve interactions between tourists, boats and sharks, while positively impacting the livelihoods of local communities.
