They move with a rapid, wriggling motion that resembles the movement of a fish through water. This behavior is the source of their common name.
Adult silverfish are generally small, often measuring around 10–20 millimeters in length, although size varies among species.
Their bodies may appear shiny silver, gray, or brownish depending on the species, age, lighting, and condition
of their scales.
Unlike flies, beetles, or moths, silverfish do not have wings. They rely on their legs to move quickly through narrow spaces, frequently disappearing into cracks when disturbed.
Why do they look so unusual?
Silverfish have a distinctive body shape that differs from that of most familiar household insects.
Their bodies are broadest near the head and middle, then gradually narrow toward the rear.
Three long filaments extend from the abdomen. Two are associated with the sides of the rear, while the central filament projects backward.
Their antennae are also long and sensitive, helping them navigate their surroundings.
