Orcs

Orcs are monstrous humanoids.

In addition to reproducing sexually, Orcs can also essentially spontaneously generate from rotting flesh; the orc-fly, a widespread pest, fly lays eggs in a rotting corpse which develop into orc young. The orcs, in turn, are host to thousands on parasitic orc-fly larvae, which quickly consume their bodies after death.

It's said that an orc's characteristics will vary depending on the type of creature its eggs were laid in, and that these characteristics are then passed down through normal reproduction. Those sprouting from human corpses are said to be particularly cunning.

Orc communities that have existed for many generations tend to be more complex and less bestial than spontaneously-created orc communities operating mostly on instinct.

The instinctual orc language is an extremely crude set of grunts, hoots, barks and squeals. Over decades, orc communities will usually develop more complex and expressive dialects, but they can always fall back on the core vocabulary of animalistic growls and shrieks to make themselves understood to other orcs unfamiliar with their parlance.
