Spiny Stone Ape

"The Po-Matoran were very fortunate that the Spiny Stone Ape is not overtly aggressive. This creature possesses tremendous strength, allowing it to easily lift ten times its own weight. Combine this raw power with sharp claws, a swordlike tail, and pincushion armor, and it is no wonder this Rahi has proven a threat even to Visorak."

- Rahaga Iruini,BIONICLE: Rahi Beasts

Spiny Stone Apes were large Rahi that defend themselves by curling up into a ball, exposing their foreclaws, bladed tail, and spiny hide. They usually make a guttural hissing to warn anyone that they might attack. They had a symbiotic relationship with Rock Raptors, living in abandoned caves and Raptor-carved tunnels while providing considerable defense for the Rock Raptors. They could be found in Po-Metru hiding among the protodermis sculptures and also inside caves in Po-Wahi.
