The 'Bowlhead' is understood to be an alien genus of gephyrostegid reptiliomorph amphibian.
Bowlheads are extremely agile hunters that inhabit the banks all along the 'JJa' river in the Faankoom Rainforest.
They will hunt down large prey in twos and threes with frightening speed, scaling the trees and swimming to get a better vantage point. Often, their best approach is to wait in the dark waters of the JJa until their thirsty and unsuspecting prey, sometimes twice their size, is dragged under and drowned.
These creatures make the journey through Faankoom a very difficult task indeed.
