An organism or creature that relies on blood circulation or hemocoel fluid for movement or support; theoretically, a blood-footed animal.
From hema- (blood) plus -pod (foot, from Greek pous). This is a rare or theoretical term combining roots to describe movement via blood.
Hemapod is a word that's barely used in English, but it represents an interesting idea in comparative anatomy—some invertebrates do use blood pressure and hemocoel fluid almost like a hydraulic skeleton!
