Tolb

Tolb is a planet about twice the size of Earth whose axial rotation is such that its tropics extend much futher from the equator. That, combined with very plentiful water, results in 60% of the planet's total surface area (nearly 80% of its landmass) being tropical rainforest or shallow sea, making Tolb the most biodiverse planet in the known universe, rivaled only by Calpha. Tolb is home to over ten million documented species, including no less than twelve intelligent, spacefaring species (possibly more that left Tolb too long ago to remember), plus an estimated 30 million more undescribed species. Tolb's massive factory of evolution has produced almost every phylum of life observed in the galaxy, including some of the rarest. Tolb is strictly regulated in terms of visitors, since interference with its ecology could prove disastrous for either Tolbian or visiting life.
