Description
The basilosaurus is king of the sea, outclassed only by certain dragons and legendary sea monsters. The basilosauraus is a terror compared to these beasts because it is more common and dwells in shallower waters, even, at times, maneuvering its massive bulk into deltas and lagoons. It must feed often to keep its massive body moving, and while it often subsists on whale pods, it will, in times of desperate hunger, attack fishing vessels and even warships, both for their crew and the food that lies within their holds.
