Stamps on animals in complete sets

The full bestiary of a postage stamp

An umbrella theme organised into twelve sections

"Animals" is the overarching category bringing together every stamp devoted to the animal kingdom, with a catalogue running well past 2,000 items. Rather than lumping everything under one entry, the shop splits it into twelve sections: birds, mammals, marine animals, reptiles, insects-butterflies, turtles and tortoises, prehistoric animals, endangered species-WWF, mixed series, plus three subjects set apart from the rest despite technically being mammals — dogs, cats and horses, popular enough among collectors to warrant their own entry.

Two-tier sub-classification

Some of these twelve sections are themselves subdivided: mammals split into domestic, wild, marine and flying; marine animals into fish, marine mammals, molluscs-shellfish and corals-jellyfish. Birds, covered in their own dedicated article, run to nine zoological sub-groups. This two-tier structure — a broad section, then finer filters — is what makes it possible to search for a specific species (a dolphin, a sea turtle, a butterfly) without having to work through the whole animal collection.

The case of multi-classified issues

The same stamp can belong to more than one section at once, which is common with this kind of subject: a Sierra Leone souvenir sheet depicting an owl appears under both "birds" and "endangered species – WWF", while a Swedish series pairing butterflies with flowers sits at the crossing point of insects and flora. These overlaps aren't classification errors — they reflect the subject itself, often straddling two themes both recognised by the issuing administrations.

A practical classification, not a scientific one

The grouping used here doesn't follow zoological taxonomy: its purpose is above all to make searching easier, which is why, for instance, a marine mammal stamp can appear under both "mammals" and "marine animals" depending on the angle the issuing administration took. The collection spans from colonial and post-war issues to the most recent releases, with prices starting around €0.20 for common stamps.
