One of the many nice things about nature is that almost everything is interesting and unique in some particular way, be it longevity, size, or far more specific traits, across all species, all domains of natural science.
All a matter of having an open and curious mind, I suppose.
Feinman was a curious character.
I suspect that with even a modest breadth of knowlegde a deep investigation of anything brings associations with existing knowledge (interest), unexpected connections and exceptions.
