Indices to navigate in the Red Data Book are placed on the left.
The main index contains a list of groups of species included in the Red Data Book. These thirteen groups have Latin names, only two of them may be not clear for non-advanced users: Pisces = Fishes, Aves = Birds. The number of species in a group is displayed in brackets. The main index is always accessible by the Index button placed above. A similar structure has the common names index accessible in the search tools page.
Usually, the displayed index contains a list of species. In this case, the right button above may have the following captions: First (displays in the right frame a description of the first species in the list), Next (displays the next one), or Refresh (reloads the current index, it occurs when the last species is displayed).
|The species names in the index are supplied with color bullets indicating the type of image:|
|- none||- black/white||- color||- photo|
|Clicking on a species name loads its description into the right frame.|
