Kyrolian
From Tardis Wiki, the free Doctor Who reference
Kyrolians were the native species of Kyrol, a type of deep sea creature which fed primarily on psychokinetic energy. They were all but wiped out when one member of their species, Kata-Phobus, a Kyrolian with an unusually large appetite, consumed the rest of his kind. The species went extinct when Kata-Phobus's ingestion of psychokinetic energy was suddenly interrupted. (COMIC: Children of the Revolution)
