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.
The PhD Movie introed with Richard Feinman's statement "I don't know anything, but I do know everything is interesting, if you go into it deeply enough."
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.
All a matter of having an open and curious mind, I suppose.
