Fikou were Rahi tree spiders. They're commonly orange, but there are also black or blue.
There was a population of Fikou in Metru Nui prior to the Great Cataclysm. These spiders used to live in the cables of Le-Metru and in some sections of Onu-Metru. They were known to live in the Fikou Web, an abandoned section of tunnels that were named because the tunnels had a similar structure to that of the webs that the Fikou spiders make.
There also was a population of a sub species of Fikou spiders in an area of the Southern Continent called Voya Nui, which developed stingers and pincers. After the Great Cataclysm, these Fikou were traped on the Island of Doom, where they remained for thousands of years. These population of Fikou spiders is persubabily dead since the Toa Mahri destroyed the Cord, sending Voya Nui back to it's original position.
Metru Nui's population of Fikou Spiders migrated to the island of Mata Nui after the great Cataclysm. They lived there for thousands of years, until the Bohrok Swarms were awakened by the Toa Nuva, and the Rahi were forced to migrate back to Metru Nui.
