Mother Longlegs

Mother Longlegs are giant arachnid monsters that first appeared in the 2017 Legendary Pictures film, Kong: Skull Island.

Personality
Mother Longlegs are carnivorous ambush predators who use their environment to their advantage by being able to blend in with the bamboo forests of Skull Island when staying motionless. They were bolder in Skull Island: The Birth of Kong, raiding the Iwi village in broad daylight after Walter R. Riccio blasted an opening in the wall and attacking the much larger King Kong.

Origin
Monarch's superspecies profile of the Mother Longlegs presents the theoretical possibility that the creatures are a supermutation of the Opiliones order of arachnids.

Kong: Skull Island
While Preston Packard and his men were passing through a dense bamboo forest on Skull Island, one of the soldiers was impaled through his mouth by the leg of a Mother Longlegs. The other soldiers looked up at the canopy and saw the colossal arachnid's body moving across the treetops. They immediately opened fire on the creature, which retaliated by trying to stab the men with her legs and using the tentacle-like structures in her mouth to try and eat them. The soldiers retaliated by slicing off the tips of the Mother Longlegs' limbs with machetes and firing on her cephalothorax, with the latter finally toppling her. Packard approached the fallen creature and fired several rounds into her head with his pistol until she died.

Camouflage
Mother Longlegs are perfectly adapted for camouflage in the dense forests of Skull Island. With their limbs resembling bamboo stalks and their bodies held high above the forest canopy, Mother Longlegs blend in seamlessly with the forest, allowing them to attack unaware prey that passes through their territory.

Legs
The Mother Longlegs' legs are razor-sharp, and can be used as deadly spears. Once a Mother Longlegs uses its legs to immobilize its prey, it will use them to inject venom into its victim's body and start to absorb nutrients from it.

Tendrils
The Mother Longlegs can release muscular tendrils from their underbelly to ensnare immobilized prey and drag them into their open stomach.

Reproduction
Due to being an all-female species, the Mother Longlegs are capable of asexual reproduction.

Weaknesses
The Mother Longlegs is not particularly durable, as its legs are easily severed by knives and bullets. Once the Mother Longlegs' legs were removed and it was brought to the ground by gunfire, she was swiftly killed by Packard. Multiple Mother Longlegs were nowhere near a match for Kong, who easily killed all of them in a relatively short struggle.
