Troysk's Tardmoid

Troysk's Tardmoid is a giant Venusian creature which was discovered by Dr. O. Troysk. They are known for their docile nature, which allowed big game hunters like Lord Cockswain to use them as mobile hunting platforms.

Their long necks are composed of both vertebrae and hinged bones. It is unknown what they feed on, for they have no mouth or similar opening. Filter feeding on atmospheric micro-organisms or surviving on air have been suggested, but none of these theories could be proven so far. In the short film The Deadliest Game, one can be seen sniffing spores out of some kind of plant with small tentacles on it's head.

While they are mostly peaceful, they can get very aggressive when fighting for a mate. Then they use their long necks as weapons.
