Giraffes re-orientate their bodies to minimize radiant heat gain and seek shade. A unique arrangement of blood vessels supplying blood to skin patches allows patches to act as thermal windows through which heat can be lost an arrangement enhanced by evaporation: sweat gland density in the skin of patches is greater than it is elsewhere.

Competitive exclusion principle - Wikipedia
In ecology, the competitive exclusion principle, [1] sometimes referred to as Gause's law, [2] is a proposition that two species which compete for the same limited resource cannot coexist at constant population values. When one species has even the slightest advantage over another, the one with the advantage will dominate in the long term.
