The Pit Spider also known as The Giant Spider was seen in the 1933 King Kong
One was seen in the deleted scene of the pit scene in King Kong (1933). A man tries to escape from the creatures of the pit but the spider pit (can be also called "The Giant Cave Spider") appears and eats the man. There's also a photo of the Pit spider during filming.the deleted scene has been reconstructed and can be found on youtube.
The reason it was deleted was due to in the pictures when people first saw it , everyone ran out screaming when they saw the spider eat the man.
