What observation about *Bipes canaliculatus* reinforces the knowledge gap concerning *Bipes biporus* lifespan?

Answer

Research limitations regarding lifespan apply equally due to its shared subterranean lifestyle

The difficulty in ascertaining the exact lifespan of *Bipes biporus* is not isolated to that species alone; similar research limitations apply to its close relatives within the *Bipes* genus, such as *Bipes canaliculatus*. Both species share the deep, subterranean lifestyle that makes direct observation and the collection of longitudinal demographic data extremely challenging. This similarity suggests a systemic knowledge gap pertaining to the entire genus regarding their natural longevity, rather than an issue specific only to *biporus*.
