How is the segment count of a Western diamondback rattlesnake rattle reliably linked to its age, given the shedding process?
Answer
The number of segments does not reliably indicate the snake's age because shedding frequency varies
While it is true that a new segment is added to the rattle structure each time the snake undergoes ecdysis, or skin shedding, the total number of segments is not a dependable metric for determining the snake's age. This is because the frequency with which any individual rattlesnake sheds its skin is variable. Factors such as nutritional intake, environmental conditions, and overall health influence how often the snake will complete a full shed cycle. Consequently, snakes of the same age can possess different numbers of rattle segments, rendering the count unreliable for precise aging.
