What you need to know about International Commission of Zoological Nomenclature?
The International Commission on Zoological Nomenclature (ICZN) was founded in 1895. Its task is to create, publish and, periodically, to revise the International Code of Zoological Nomenclature.
- The Commission also considers and rules on specific cases of nomenclatural uncertainty.
- These rulings are published as ‘Opinions’ in the Bulletin of Zoological Nomenclature.
- The maintenance of international standards in animal nomenclature is the unique role of the Commission.
- It is not the role of the Commission to become involved in taxonomic issues except where they have nomenclatural implications.
The Commission currently comprises 25 members from 18 countries. The work of the Commission is supported by a small Secretariat based at the Lee Kong Chian Natural History Museum in Singapore. The Commission operates in two main ways:
- ICZN publishes the International Code of Zoological Nomenclature containing the rules universally accepted as governing the application of scientific names to all organisms which are treated as animals.
- ICZN provides rulings on individual nomenclatural problems brought to its attention, in order to achieve internationally acceptable solutions and stability. These rulings are published as ‘Opinions’ in the Bulletin of Zoological Nomenclature.

ZooBank is the official registry of Zoological Nomenclature, according to the International Commission on Zoological Nomenclature (ICZN). Currently, ZooBank accommodates the registration of four different kinds of data objects:
- Nomenclatural Acts: Published usages of scientific names for animals, which represent nomenclatural acts as governed by the ICZN Code of Nomenclature. Most of these acts are ‘original descriptions’ of new scientific names for animals, but other acts may include emendations, lectotypifications, and other acts as governed by the ICZN Code.
- Publications: Publications that contain Nomenclatural Acts, as defined above.
- Authors: Anyone who is an author of one or more Publications (as defined above), or who is a contributor to ZooBank content.
- Type Specimens: Type specimens for scientific names of animals. The registration of Type Specimens is considered provisional and is not yet fully implemented in ZooBank.
