I was a litte bit confused because of the difference between a troglodyte and a troglobite. So I took the consequence and changed the name of the project.
This is an amphibious, hominid Troglobite. They are blind and inhabit a huge subterranean cavern system. Every season the males go on a journey to bring the fertilized spawn to a well kept secret place. On their way they have to resist several perils.
