On my recent visit to the Galapagos Islands aboard the Letty, I was excited to have the opportunity to snorkel with sharks. The white-tipped reef shark is the most common and can often be seen cruising around rocky reefs, coral head and inside caves. This one came out into the open which allowed me to follow it for a good five minutes. They are docile sharks that feed at night and are not generally thought to be dangerous to humans. They can grow to over two metres.
