Where to get life history details of all the animals on our planet?

I am looking for their time of gestation, birth, death spread across the year or at least season wise as seasons have different timings spread across a the year in different biomes and hemispheres.

For fishes only, there is of course fishbase

And the rOpenSci project offers R packages to interact with a lot of databases having the information you want (eol and fishbase are covered)
