They are quite small crocodiles really. Toddy has done an article on Asian Crocs for my site and here's the bit about Philippine crocs:
The philippine crocodile (crocodylus mindorensis) has recently made a comeback into the European zoos. Crocodile Zoo in Denmark has managed to import 15 philippine crocs from a farm in the Philippines, and they are now being distributed around to other European zoos. These include, London Zoo, Chester Zoo, Zurich Zoo and the Bergen Aquarium. The philippine crocodile is the second smallest species of crocodile, with an average maximum length at only 2,5 meters (8,20 feet). Its favourite habitat is marshland, and it lives spread throughout the Philippine islands. It is classified as critically endangered; with only 27 ISIS registered crocs, beside those 15 from Crocodile Zoo. Until very recently, the philippine crocodile was considered to be a subspecies of the New Guinean crocodile.
