Koristocetus (SciiFii)

The razor-toothed sperm whale (Koristocetus marinus), also simply known as the razor-toothed whale, is a small species of sperm whale from the Kogiidae family, which also contains two other species, the pygmy sperm whale and the dwarf sperm whale. The razor-toothed sperm whale was once extinct since the Miocene, but has since been brought back from extinction by SciiFii and introduced throughout the modern world's oceans to help boost biodiversity. Unlike its two relatives, it has teeth in both the upper and lower jaws, which are somewhat longer than in pygmy or dwarf sperm whales, allowing for more raptorial feeding instead of mostly feeding by suction. Like its relatives, the razor-toothed sperm whale has one of the defensive mechanisms, the sudden expulsion of a dense cloud of excrement that works like a cephalopod's ink cloud, momentarily concealing the whale and allowing for a quick escape. However, if that doesn't work, it may use its sharp teeth in its jaws for defense, making it dangerous when cornered or threatened. The conservation status of the razor-toothed sperm whale is Least Concern due to successful conservation efforts and the razor-toothed sperm whale's wide range.
