If I had a mate like you

It is quite simple. So old is he, but also picky, serpents are males who pride themselves in beauty. Powerful females, and just as powerful offspring, a hiss escaped from the serpent remembering what happened to its nest.

They may breed many young but how many survive?

 Have a female to mate, but how long will she survive when they aged so slowly? When their genome... Genetic code made them so vulnerable in the first thousand forestry cycles of their lives?

Mature enough to breed at three hundred but unable to protect their female. Greedy, unable to share their female so they can guard the eggs, protect her and nurture their young. Even if they nurture their young; til when?

 The young they see as an enemy and at a century because the females become attached; male or female, they would banish them from their territory.

What can a female do?

 The males as well?
