Insectomammal

Insectomammals were species which had features of both mammalian and insectoid species. Keerzachi were a sentient example of insectomammals.

Insectomammals often combined insectoid characteristics such as exoskeletons, antennae, mandibles, egg-laying, and open circulatory systems with mammalian characteristics such as skin, teeth, hair, delivery of live young, and closed circulatory systems. The exact combination of traits varied from species to species.

Insectomammals were generally rarer than s, as evolution was less likely to evolve mammalian creatures from insect ancestors than from reptile ancestors.
