Chelonthrias are hermaphrodites. They constantly reproduce by producing a massive amount of eggs on their underbellies. It uses its tentacles to remove the eggs and then store them inside the shell as they are hatching. The Chelonthria then feeds the infant chelos by regurgitating mostly digested food with its many mouths. Once the Chelos begin to grow the makings of their own shells, they leave their parent's shell to live on their own. If the main head of a chelonthria is severed, another head will almost instantaneously take over as a new main head.
