How to use a retrieval table

When we encounter an unknown plant or animal, we should look for the taxonomic status of the plant and animal one by one according to their morphological characteristics and the order of the key table.

How to use:

1. Determine which phylum, class and destination animal and plant it belongs to, and then continue to search the key table of animals and plants by family, genus and species.

2. When using the key table of animals and plants, it is necessary to observe or dissect the animal and plant specimens in detail, and understand that all organs should be carefully checked according to the key table.

3. For the completely matched items, continue to search downwards until the end point is retrieved.
