We\u2019ve brought this group of vulnerable marine species together to mark World Ocean Day. The focus is on habitat loss and overfishing, and the need to protect and create safe areas in which rare creatures may recover and perhaps thrive once again. There is precedent. The largest animal on the planet, the blue whale, was hurtling towards extinction at the hands of harpooners until a ban on hunting came into effect in 1966. From just a few hundred individuals at their lowest ebb, there are more than 2,000<\/a> blue whales alive today.<\/p>\n\n\n\n

Chinese crested tern<\/strong><\/strong>By 1937, the crested tern was considered extinct. Then, in 2001, researchers discovered two pairs nesting on a rocky islet in the Yellow Sea. More have since been found, hidden among the nesting sites of greater crested terns and black-tailed gulls. Clever conservation efforts involving playing audio to attract the birds to suitable nesting sites appear to be working.

Each year, many red knots migrate 15,000km from the southernmost tip of Latin America to the Canadian Arctic and back again.
