Swim with Philippines' Whale Sharks that are 10 Times Heavier than a Car Swimming with whale sharks is the ultimate underwater adventure for every thrill seeker. Whale sharks are the world’s largest fish and can grow up to 12 meters in length and can weigh up to 20 tons. I will never forget the first time I saw a whale shark. I knew they were big but did not realize their scale until I saw them up close. The shark was docile and was graciously swimming around, looking for food. Before I knew it, I was surrounded by four giant whale sharks. Although I was careful of keeping a distance of at least 4mt from the beasts, they did not seem to be aware of the rule! Extremely curious, a couple of them swam to almost touching distance of me. Trying hard not to freak out, I grabbed my GoPro and took a few photos of the sharks. I have photographed several wild animals in the past, but this was one of the most thrilling experiences I have ever had.
