What behavior do silverfish exhibit throughout their growth process?

Silverfish exhibit instars that closely resemble one another throughout their growth process. This characteristic is attributed to their classification as primitive insects. Unlike insects that undergo complete metamorphosis, such as butterflies, silverfish go through a series of molts, known as instars, where they gradually grow larger without changing significantly in form or body structure.

This gradual development allows them to maintain their overall appearance while their size increases. Each instar may show slight changes in size and color, but the fundamental body shape remains consistent throughout their life cycle. This continuity in morphology is a defining feature of silverfish and is essential for understanding their developmental biology and behavior.

The other options suggest a level of transformation or changes that do not accurately reflect the nature of silverfish growth, reinforcing the validity of the understanding that they remain relatively uniform in appearance as they mature.
