Razor Whales were peaceful Rahi, despite their formidable appearance. Razor Whales had no natural enemy, although Nocturn would eat them when they came to the Razor Whale's Teeth near the Pit. They had a row of spines down their tail, which they used to scare off predators. At some time in the whale's life, the spines in its tail would fall off. Strangely, after this happened, the Rahi would be easier to tame. Toa Hordika Nokama made an extra effort to protect these creatures from the Visorak, but since few specimens were seen off the Mata Nui coast, it remains unknown how successful she was. Elsewhere on the surface of the planet, however, Razor Whales could be found at the Razor Whale's Teeth near Mahri Nui.
