Some marine mammals like seals and dolphins are said to possess what is sometimes referred to as a ‘diving reflex’, a physiological function which is thought to partially activate when the face or head is immersed in cold water. Some bodily functions then temporarily change to conserve oxygen, allowing these mammals to remain underwater for long periods of time.
Two indo-pacific bottlenose dolphins have been returned to the wild in off Jeju Island in South Korea, 20 years after being illegally captured.
In April, local authorities led by mayor Park Wan-soon ruled that the dolphins, Geumdeung and Daepo, must be released. Since then, they have undergone a rehabilition programme to prepare them for life in the wild. It is hoped they will join up with a local population of around 100 other dolphins.
