It is no mystery where Howler Drakes got their names. Though not very bright, these emotive creatures employ an impressive vocabulary of loud chortles, shrieks, and songs to communicate with one another, and almost never stop chattering. Howler Drakes inhabit dense jungles, foraging in the fertile soil for mushrooms, tubers, and insects. When threatened, a Howler will flare its wings to display its bright red eye spots, while letting out an ear-splitting scream.

Though it may appear at first that dragons and drakes have much in common, the two are completely separate species. Drakes are smaller and less intelligent than their cousin species, though both dragons and drakes sit comfortably near the top of the food chain. They are always found bearing antlers and leathery wings. Drakes share many of the same habitats that dragons do, and typically hunt in packs.

Sumitori, like his elder Howler Drake brother, helps teach hatchlings how and when to use their roars as a defensive tactic. While he is not particularly good at avoiding predators entirely, Sumitori has repeatedly encountered enough of them to remember how to react, whether allowing them to approach before a threat scream or demonstrating aggression immediately. Oddly enough, Sumitori's own scream is unsettling and intimidating enough to stun most predators, but he actually dislikes conflict and attempts to avoid it whenever possible.
