Remarkably little is known about great white sharks, but they are similar to humans in a lot of ways – they give birth to live young, maintain a higher body temperature than their surroundings and they are apex predators. There are also many misconceptions about these sharks: people think they don’t get cancer and that they reside mainly in shallow waters near beaches. In this video I summarize some of the most interesting things I learned about sharks on my cage diving adventure.

Special thanks to Rodney Fox Shark Expeditions for making this trip possible:

Thanks also to Tourism South Australia for facilitating the trip:

Chris Cassella or C² as he is known after this trip was a shark spotter extraordinaire. He also took some of the best shark footage in this video. It was his idea to go on this expedition, which was definitely a once in a lifetime experience, so I am in his debt. Chris, I look forward to going on more great adventures with you.
