Alteration (influenced by porpoise) of Middle English tortuce, from Medieval Latin tortūca, alteration of Late Latin tartarūcha, feminine of tartarūchus, of the underworld; see turtle1.(American Heritage® Dictionary of the English Language, Fourth Edition)
Middle English tortuse, tortuce, tortuge, from Medieval Latin tortuca, possibly from Late Latin tartarūcha, from Late Latin tartarūchus ("of Tartarus"), from Ancient Greek ταρταροῦχος (tartarouchos, "from Tartaros, Tartarus, the land of the dead in ancient stories"), because it used to be thought that tortoises and turtles came from the underworld; or from Latin tortus ("twisted").
