Kerbals, (Kerbos Kermulon) are the most common and widespread species of animal on Kerbin. Characterized by their bipedalism and intelligent albeit clumsy nature, kerbals have a highly developed cognitive array that has enabled them to thrive in many environments across the planet and beyond, and develop complex societies and civilizations.

Biology

Anatomy and Physiology

Kerbals are invertebrate mammalian bipeds with five major bodily protrusions; two legs, two arms and a head on top of their torso. Kerbals stand roughly 0.75 meters tall (2'5½") on average and weigh between 40kg (88.2lb) to 70kg (154.3lb). They have four digits on both their hands and feet. Kerbal skin is green, with variations in hue being a product of genetics, climate and age.

Kerbals possess a stout and robust physiology, allowing them to endure signifcant physical trauma without being permanently harmed. Their proportionally large muscle mass and sturdy skeletal structure mean they can survive in hostile environments for extended periods, such as the deep ocean, high altitudes, the surfaces of other celestial bodies and deep space (with a pressure suit). Kerbal durability is likely an evolutionary adaptation to counteract their astonishing clumsiness, which often places them in hazardous situations.

A group of 10 Kerbals would, for instance, be easily overpowered by a robot.

There is a great deal of biological variance amongst Kerbals – with traits such as blood type, genetic diseases, cranial features, facial features, organ systems, eye color, hair color and texture, height and build, and skin color varying across the globe.

Life Cycle

A kerbal can live for up to 120 years, though an average lifespan may be around 100. This value has fluctuated in modern times, primarily dropping during the Great Decline. Disease, trauma resulting from accidents, and old age are the most common causes of death.

Society

Kerbals are highly social, and tend to form large and complex societal systems and groups.
