World’s nations gather to tackle wildlife extinction crisis

Giraffes, sharks, glass frogs - and the woolly mammoth - may get boosted protection at summit

From giraffes to sharks, the world's endangered species could gain better protection at an international wildlife conference.

The triennial summit of Convention on International Trade in Endangered Species (Cites), that began on Saturday, will tackle disputes over the conservation of great beasts such as elephants and rhinos, as well as cracking down on the exploitation of unheralded but vital species such as sea cucumbers, which clean ocean floors.
