These large Cardiocetes are usually heard rather than seen underwater with their throbbing jet-beats reverberating across the waves. While they superficially look like the Monocardiac giants of the north, the construction of their mouths, multiple jet-hearts and even their feeding strategies set them apart as Polycardiac Cardiocetes, albeit huge and filter-feeding ones. Their filter-feeding is more like taking bites out of the giant plankton swarms, rather than passively swimming through them like their Monocardiac cousins. They have also secondarily tuned down the engine-like multiple jet-hearts of their lineage, pumping along at a leisurely pace instead of the jet-ski-like frenzy of their smaller relatives.
This species is readily identifiable through its tapering, ram-like snout extension, used in a variety of social activities such as friendly snout-rubbing with members of the same pod, sexual displays for potential mates, and outright ramming against intruders or rowdy males. There are at least four separate species of Biogalleas in Snaiadi oceans, with one, B. polaris, also widespread in the Northern Hemisphere.
