The lifespan of coelacanths is not well-documented, as their deep-sea habitat and elusive nature make it challenging to study them in detail. However, it's estimated that coelacanths can live for several decades. Some scientists suggest that they may have lifespans of 60 years or more, but this is based on limited data and observations.
More research is needed to determine the precise lifespan of coelacanths. Their slow growth rate and low reproductive rate contribute to the difficulty in studying their life history and longevity.
