Mother Longlegs are huge spiders that lived in the jungles of Skull Island.


They appeared to be large spider like creatures that lurk in the jungles of Skull Island, They possess long slender legs that resemble bamboo stalks, allowing them to camouflage in the surrounding forests, with their legs posing as plants and their upper bodies held high above the canopy in order to either stab the victim with their sharp poisonous tips from each of their legs or unleashing their tendrils to grab the victim and drink it (instead of eating them). Their faces resemble skulls, being brown in color with large crimson eyes. The arachnids possess two additional crustacean like pincers located closer to their heads.

Despite being dangerous, even their legs were fragile and thin which would be easily cut off and the spider will drop and become helpless.

It has been stated by Monarch that the entire species are all females.


  • Before the film was released, many fans were concerned that the spider was Kumonga, but actually wasn't.
  • Its appearance may have been inspired by the crab-spiders from the "deleted" insect pit scene from the 1933 version of King Kong.
