Interpreting fin count meristics.
Spines are in Roman numerals and soft rays are in Arabic numerals. Spines and rays that are continuous in one fin are separated by a comma. Fin sections are separated by semicolons.

Order level detail.
A group of small to medium-sized ray-finned fishes with both freshwater and marine life stages. Most spend their lives in freshwater and spawn in the lower reaches of rivers and streams. The larvae develop in the open ocean, before migrating back to freshwater as juveniles called "whitebait". The order contains three families, two of which are found in Australia.
