Trigopods were a food source used by the Delvians of the New Moon of Delvia. They were kept in a pool in the center of the Delvian ship of Pa'u Tahleen, where they swam serenely about amidst bubbles and rose petals, eating, and breeding. John Crichton noted that they were "untended, renewable, it's part plant, part animal. Total nutrition... it's a squid-calamari-cucumber, and it... is incredible." Rygel found them delectable.
