"no evidence that this shark swallows its shed teeth like the pygmy and cookiecutter sharks. The spined pygmy shark is aplacental viviparous like the rest of its family, with the developing embryos being sustained by a yolk sac until birth. Adult females have two functional ovaries that may each contain up to 12 mature eggs.
