How does the naming convention for biological sub-families often end?

The naming convention for biological sub-families typically ends with the suffix "...idae." This suffix is used in the classification hierarchy of biological taxonomy, specifically for animal families. For example, in zoology, the family classification for cats is Felidae, while for dogs, it is Canidae.

Understanding this suffix is essential for recognizing relationships between different groups of organisms. In contrast, the suffix "...aceae" is primarily associated with plant families, particularly in botany, while "...ium" generally denotes certain plant genera and resonates more with structures or elements found within plants or fungi. The suffix "...itis" relates to inflammation and is commonly used in medical terminology rather than biological classification. This highlights the importance of the suffix "...idae" as the correct representation for animal sub-families within the context of taxonomy.
