The cave is known as the "Wonder Hole" or the "Bottomless Pit". Supposedly, it connects to the sea which is 40 miles away. According to local legend, the cave is filled with diamonds. It is also said to live in warm rivers and lakes. In Benin, it is said to be a huge elephant-like creature with a serpent's tail. Sometimes, it is depicted as a snake with orange gems for eyes. Also according to the tale, Grootslangs covet gems, particularly diamonds, and despite the creatures' lust for cruelty, victims can often bargain for their freedom by offering a Grootslang enough precious gems. While searching for treasure in the richtersveld of South Africa in 1917, English businessman Peter Grayson disappeared after members of his party were attacked and injured by lions, prompting legends that the Grootslang had killed him. It has also been featured in the TV show "Secret Saturdays".
