Their physiology is significantly different from those of the material plane, and as such, water seems to be corrosive to them. They will take damage from coming in contact with water like a carbon-based lifeform would take damage by coming into contact with acid. They will seek refuge if injured by such material - including rain - by teleporting into subterranean caverns where they feel safer. Strangely, they are not injured by standing in a cauldron, and therefore whatever their actual physiological make up happens to be, only pure water seems to cause cellular degradation. Endermen also dislike sunlight and fire, and they will flee these elements as well.
Through unknown means they are able to slip between The End and various locations in the Minecraft World, and occasionally the Nether. They use this both as a method of fast travel as well as a way to distance themselves from anything that has harmed them. They are intelligent enough to teleport away from any sort of projectile in most instances. Studies have revealed that after injury an Enderman will attempt to teleport subsequent 64 times until one of these attempts is successful. They seem to be trapped by iron-wrought minecarts in a similar manner to some types of vampires, and they not only cannot attack a being hiding within one but are entirely incapable of teleporting out of one as well if they are ever successfully trapped inside one. This may indicate that their physiology may be radioactive isotope-based, though this would hold more water if the minecarts were made of lead. They are apparently incapable of teleporting during the daytime as well, and for some reason will not teleport if struck in the legs, indicating that whatever organ allows their slipspace traversing may be located in these limbs and thereby striking them in the legs may disrupt their capabilities.
Endermen, despite their creepy appearance, are not normally interested in the affairs of men and instead will ignore them unless provoked. Unlike most humans but similar to dogs, Endermen see looking direct at them (and especially the eyes) as a threat and so a cautious adventurer will only view Endermen using their peripheral vision. When angered, an Enderman will open its mouth and shake with rage and if this provocation is from being stared at they will also emit a lengthy, loud and threatening call before charging their would-be opponent. Interestingly however, Endermen still seem to view humans as the least of their worries, and if attacked by any other creature they will cease their attack against the adventurer; otherwise they will continue to give chase until they are either killed, have been seriously injured, or become distracted with other elements such as rain, fire, or sun.
Endermen may be confused by transparent material such as glass and do not seem to automatically associate the face of a jack-o-lantern as looking at them, meaning humans can view them either through a window or while wearing a pumpkin on their head, respectively. They are also apparently confused by minecarts, and for some reason will not attack someone who is hiding in one.
Endermen hate Endermites, at least those spawned by ender pearls, but will only fight them if there are no humans nearby, as it appears Endermites are considered an even lower priority than adventurers. They have been known to watch humans as they sleep and sometimes will knock them out of bed.
In a manner similar to certain ancient beings, Endermen are known to move bits of terrain around, although the purpose of this is not understood at all. They seem to take pride in this artful rearranging, and while they are perfectly capable of building Golems through manipulation of terrain, study has proven this to be entirely inadvertent on their behalf.
Interestingly, while Endermen will move a large list of terrain and vegetation around, they will not move everything. They will however move clay, dirt (both coarse and fine), gravel, podzol, and sand (regular and red), as well as specific plantlife that includes Allium, Azure Bluet, Blue Orchid, Dandelion, grass clods, melons, both brown and red species of mushrooms, sections of mycellum, Orange Tulip, pumpkins, Red Tulip, Pink Tulip, White Tulip, Oxeye Daisy, Poppy, and Cactus. They will also move TNT.
