Sailors passing through the island of Vava'u, Tonga were treated to a beautiful and playful encounter with a mother and calf pair of humpback whales. <br /><br />The calf is seen eyeing up the camera before playfully swimming under his mother, before both disappear into the distance. <br /><br />The video was shot by Captain Marjan Golobic, who was sailing through the island as part of a global circumnavigation that started in St. Martin in the Caribbean. <br /><br />The Vava'u lagoon serves as a breeding ground for humpback whales, where they look after their calves until they are strong enough to swim the open oceans.
