Trivia

 * It appears from the transcript above that Bungie originally did not know what to name the creature, and simply fused "Doberman" and "Gator" together to form the label "doberman gator."
 * Its anatomy also slightly resembles that of the prehistoric Gorgonopsids which lived on Earth within the Permian. There are also similarities between it and Ambulocetus; an aquatic as well as terrestrial ancestor of Earth's Cetaceans which lived throughout the Eocene.
