Record Holder of the Seas Whales, the largest mammals on earth and record setters in breath-hold diving, can be found in all the world’s oceans. They are more scientifically known as cetaceans, which include all whale, dolphin, and porpoise species. There are approximately 90 cetacean species, the most well-known being the Blue Whale, Sperm Whale, Humpback Whale, Minke Whale, Orca (also known as the Killer Whale), and dolphins. Cetaceans are very social animals and often live together in groups called pods. It is an extraordinary adventure to dive with whales and dolphins and to experience their social behavior directly underwater. These animals have breathing and circulatory systems specifically adapted for life in icy water. Their organs are protected by a thick layer of blubber which gives their bodies insulation of up to half a meter. As a scuba diver, adjusting to the cold becomes a secondary issue when diving with whales as the thrill of watching them move gracefully through the water takes over. You will never forget a moment such as this.
