The six new-born critically-endangered crocs - born over a 48 hour period - are among the world's rarest reptiles.

As they are native only to the Philippines the baby crocodiles were named after the islands they typically inhabit; Jolo, Luzon, Mindoro, Samar, Sulo, and Mindanao.

It is hoped that their arrival will help to boost the numbers of the species which has been hit by habitat loss and hunting for their skins.

The parent crocodiles. which play a significant role in the European breeding programme for the species, were born at a conservation centre in the Philippines.

Deputy Head of the Reptile House, Iri Gill, said: "The arrival of these six Philippine crocodiles at ZSL London Zoo is a massive cause for celebration for us, and we couldn't be more thrilled."
