Photo by @bertiegregory // Meet the biggest fish in the world, the whale shark. Despite being a shark that can grow over 12m long (40ft) and
weigh over 20 tonnes, they don't have big teeth. Instead, they have about 3000 very very tiny teeth. Similarly to the baleen whales (e.g. humpbacks), they are filter feeders. Here you can see this huuuge individual sucking in a big mouthful of water to extract
the plankton. I was lucky enough to film and photograph the largest known aggregation of whale sharks on the planet off the coast of Mexico over the weekend. Having a school bus sized animal swim towards you out of the blue is certainly a feeling I'll never
forget!
