Philippine Stamp: National Bird (Philippine Eagle)

The Philippine Eagle (Pithecophaga jefferyi) is a critically endangered eagle species endemic to the forests of the Philippines. 

The Philippine Eagle was discovered British naturalist John Whitehead in 1896 and was named after his father Jeffery Whitehead. The bird was originally called Monkey-eating Eagle, due to the previous belief that the eagle exclusively preyed on monkeys, hence the generic name Pithecophaga. 

On July 15, 1995, Fidel V. Ramos, then President of the Philippines, signed Proclamation No. 615, declaring the Philippine eagle as the national bird.

Canadian Stamp: Skunk

Skunks (in the United States, occasionally called polecats) are mammals best known for their ability to secrete a liquid with a strong, foul odor. General appearance varies from species to species, from black-and-white to brown or cream colored. Skunks, together with their closest living relatives, the stink badgers, belong to the "skunk family", the "Mephitidae" and to the order Carnivora. There are twelve species of Mephistids, which are divided into four genera: Mephitis, the (hooded and striped skunks, two species), Spilogale the (spotted skunks, four species), the Mydaus or stink badgers, two species), and Conepatus, the (hog-nosed skunks, four species). The two stink badgers in the Mydaus genus inhabit Indonesia and the Philippines; while all skunks inhabit the Americas from Canada to central South America. 

Canadian Stamp: Peary Caribou

The Peary Caribou (Rangifer tarandus pearyi) is a caribou subspecies found in the high Arctic islands of Canada's Nunavut and Northwest territories. They are the smallest of the North American caribou, with the females weighing an average of 60 kg (132 lb) and the males 110 kg (243 lb). In length the females average 1.4 m (4.6 ft) and the males 1.7 m (5.6 ft).

The Peary caribou, called tuktu in Inuinnaqtun/Inuktitut, is a major food source for the Inuit and was named after Rear Admiral Robert Peary.

Australian Stamp: Tasselled Anglerfish

The Tasselled Anglerfish (Rhycherus filamentosus), also called Tasselled Angler and Tasselled Frogfish, is a type of frogfish and is of one of over 200 anglerfish species.

Tasselled Anglers are brown to red above. They have dark blotches or bars on their sides separated by whitish areas extending up from below. Its dorsal fin has four parts: a long illicium with an esca that resembles two worms, a second and third dorsal spine, and 12 to 13 soft rays.

The Tasselled Anglerfish is very similar to the Glover's Anglerfish. They can be separated by the shape of their escas and length of the illicium, which is longer in the Tasselled Anglerfish.

It is endemic to Australia, living on kelp covered rocky reefs from Bass Strait to South Australia.

New Zealand Stamp: Kōkako

The Kōkako (Callaeas cinereus) is a forest bird which is endemic to New Zealand. It is slate-grey with wattles and a black mask. It is one of three species of New Zealand Wattlebird, the other two being the endangered Tieke (saddleback) and the extinct Huia. 

The Kōkako illustrated is a North Island Kōkako (Callaeas cinerea wilsoni). It has blue wattles while the South Island Kōkako (Callaeas cinerea cinerea) by contrast has largely orange wattles, with only a small patch of blue at the base.

The North Island Kōkako is now quite rare—barely surviving its orange-wattled South Island cousins, considered today to be extinct. Kōkako populations throughout New Zealand have been reduced by the predations of mammalian invasive species such as possums, stoats, cats and rats and their range has contracted significantly.

It is a large butterflyfish, at up to 30 cm (nearly 12 in) long together with the Lined Butterflyfish (C. lineolatus) the giant among its genus. In shape it resembles certain angelfishes more than most of its relatives. The overall color is yellowish grey, with a large black spot bordered below by a broad white band on the back and wavy blue lines on the lower sides. The throat and the outline of the hind parts is bright yellow. Adults have a filament extending posteriorly from the upper part of the soft portion of the dorsal fin.

The crown-of-thorns starfish (Acanthaster planci) is a large nocturnal sea star that preys upon coral polyps. The crown-of-thorns receives its name from venomous thorn-like spines that cover its body. It is endemic to tropical coral reefs in the Red Sea, the Indian Ocean, and the Pacific Ocean. As solitary animals, they feed alone and maintain a distance between themselves and other members of their species.

The crown-of-thorns is the second largest sea star in the world. Only the sunflower starfish is larger.
