Arachno-claws are oversized arthropods from the 2005 movie King Kong. They live in the caves branching off from chasm walls. There they remain until their antennae sense that something has fallen into their domain. They have six legs that are used to walk, with two crab-like claws under their mouths, which are used to rip prey into easily digestible pieces.
They have a very strange life cycle that begins when the parents lay microscopic eggs in rotting carrion. Most are either killed by other scavengers or drowned in the muddy water that collects in the bottom of the pit. Lucky Arachno-claw will survive long enough to be ingested by mature Carnictis, where they live their first few years in the creature's gut as parasites. When they are old enough to leave they either emerge from their host's anus or eat their 'home' inside out. Once free they scuttle off to join their insect counterparts in the abyss.
These huge insects are carrion-eaters from the deep abyssal pits, every animal that falls, dead or alive, will be eaten by the arachno-claws and the other horrible creatures from the deep. Their hunting tactics are the ambush. They look like a giant trapdoor spider, with six legs and powerful claws.
In the original movie, those sailors that have survived the fall from the log, all of them were eaten by an arachno-claw, a giant worm with tentacles, a colossal lizard and a monstrous crab, in the 2005 remake, Carl, Jack, Jimmy and the other sailors were attacked by some arachno-claws, but were saved by Bruce Baxter and the remaining sailors.
