Nineteen of the world’s most critically endangered crocodiles were released into the wild in the Philippines as part of efforts to save the species from extinction, conservationists said.

The freshwater crocodiles, which had been reared for 18 months at a breeding centre, were set free in a national park in the remote north of the country that is one of just two remaining natural habitats for the reptile.

If they survive, the number of known Philippine crocodiles in the wild will increase by roughly a fifth, according to Marites Balbas, spokesman for the Mabuwaya Foundation that is behind the conservation programme.

“The Philippine crocodile is the world’s most severely threatened crocodile species with less than 100 adults remaining in the wild. It could go extinct in 10 years if nothing is done,” Mr Balbas said.

The International Union for the Conservation of Nature lists the Philippine crocodile as “critically endangered”, just one step away from being extinct in the wild.

The Philippine crocodile has plunged to the verge of extinction due to destruction of its habitat, dynamite fishing and killings by humans who consider it dangerous, said Mr Balbas.
