The Yautja are extraterrestrial creatures with their own unique anatomy and biology, although there are some similarities to humans. Here is an overview of Yautja anatomy, including its blood, bones, dreadlocks, mandibles and skin. Find out how many fingers and toes the Predators have, what their dreadlocks consist of, whether their blood can neutralize Xenomorph acid and speculation of and how long do the Yautja live.
The Predator blood is a bright green bioluminescent fluid. In comparison to Xenomorph blood which is acidic, Yautja blood is said to be alkaline and even neutralize some of the effects of the Alien acid which can come into contact with the Predators during combat. The Predators can lose a lot of blood and still continue functioning. The Yautja blood is warm like human blood and some sources have indicated it contains healing powers if utilized as a serum for humans.
Predator Skull and Bones
The Predator bones are bigger and sturdier than human bones. They also seem to be white in color as seen by the skull in the Predators movie. Even with their tougher bones, the Predators are still often dismembered and even decapitated, so they still fall victim to sharp blades. The bones can heal well, for example when an Engineer broke the arm of Ahab, it appeared to have healed in a few days. The Predators like to keep the bones and especially skulls of their victims, even if they have been members of their own race.
The color of the skin of the Yautja depends on the type of the Predator and other factors. The most well-known Predator - the Jungle Hunter had brownish skin. There is also a white-skinned Predator - the Alpha Predator recently seen in Predator: Hunting Grounds. Most likely, the skin is also thicker than human skin, and aids in absorbing damage from melee weapons and bullets. The arms and chest are also covered in small spike-like appendances, smaller versions of the dreadlocks. Besides armor and the cloak-netting, the Predators don't wear and clothes on their skin and prefer to hunt in warm climates.
The Predators are well-known for their long dreadlocks, which serve as the Yautja version of hair. Like human hair, they can be styled and decorated. However, some sources indicate that Yautja dreadlocks actually have blood flowing inside them, so they would be difficult to cut. Some Predators have had their dreadlocks removed, albeit against their will. For example, the captured Stone Heart Predator had all his dreadlocks removed as part of a brainwashing program to turn him against his brethren. Like in humans, the dreadlocks grow with age and turn to a grey or white color in the case of Elder or Ancient Predators. One of the Predators with the longest known dreadlocks in the Shaman Predator, part of the Lost Tribe of Predators.
The Predators don't communicate by their mandibles, although the crab-claw like appendances do make a clicking sound that can intimidate their prey. The tusks can be broken, and don't grow back, as seen in the case of Greyback from Predator 2. The tusks can also be used as a last resort defensive weapon - the Assassin Predator bit off the head of a Stargazer soldier using his mandibles. In a neutral state like when wearing a mask, the mandibles are kept in a closed position.
The Predators have five fingers on each of their clawed hands, including a thumb. They have long black nails that could be used in defense, however they prefer to use their wristblades instead. Some Predators have known to wield more than two hands. For example the Four-Armed Predator from the Predators sequel comic was possibly a genetic mutant. The Yautja prefer to not wear gloves, even in cold Antarctic temperatures.
The Predators have five toes on their feet. However the fifth toe is on the side of the foot and often difficult to see, and Predators are mistakenly thought to have only four toes. Like their fingers, the toes are covered with sharp nails. The Predators prefer to hunt either bare footed or wear sandal-like foot-wear. Their feet are large and the Yautja would make great swimmers. Perhaps there is a connection to their reptilic past in the swamps of Yautja Prime.
As mentioned previously, the Yautja often lose a limb in combat and continue to fight on. They are able to cauterize their wounds using the medicomp - a blueish goo is applied to the wound that stops the bleeding. There are no known cases of Predators using prosthetics or robotic limbs. However, the Predator named Yaquita used a wheelchair-like apparatus in the Rage War trilogy after losing her legs in combat. Some Predator books and comics have hinted that the Predators have the ability to regenerate their limbs, but there are no good examples of any Yautja doing this.
The Yautja can live at least several centuries and some have known to live several millennia. However, often they don't live through their hunts and die in combat, as no Predator has yet to survive the events of a Predator movie. Similarly to humans, their dreadlocks turn grey and skin gets wrinkled. Also, experienced Predators often have a lot of scars and might be missing an eye, tusk, or a limb. With age, their strength and reflexes can wither, but their minds remain sharp and the experience gives them a good edge over their opponents. One of the oldest known Yautja is the Ancient Predator from Predator: Homeworld, who dispatched three young bad blood Yautja in single combat.
