A Mutagenic Origin Theory

A Mutagenic Origin Theory
The suspected source
Denise connects the creatures’ mixed characteristics to a mysterious substance associated with the old submarine near Wrecker Island. She suspects generations of feeding and mutation have shaped the sliggers.
Danger beyond the predator
If contaminated tissue enters the food chain, other animals could be affected. The threat is therefore not limited to direct attacks by living sliggers.
The Warning Against Explosives

The Warning Against Explosives
Killing is not enough
Mason warns that destroying sliggers explosively could scatter contaminated tissue into the water. Scavengers might then consume remains and continue the chain of exposure.
Disposal becomes part of combat
The responders must collect bodies as well as defeat living animals. A clean victory requires handling the aftermath with the same care as the attack itself.
Fire Becomes Procedure

Fire Becomes Procedure
Destroying eggs and carcasses
Teams burn nests, eggs, and recovered remains using gasoline or other controlled means. They coordinate disposal with authorities instead of leaving material behind.
An improvised safeguard
The technique responds to a biological risk that remains incompletely understood. It is a precaution grounded in the possibility that living or dead tissue could carry the dangerous mutation.
Scientists Join the Cleanup

Scientists Join the Cleanup
Expertise follows the hunt
Denise and the other researchers do not remain in laboratories. They accompany field teams to advise on claws, carcasses, and safe handling.
A shared responsibility
Soldiers and scientists coordinate their work, with researchers explaining why remains must be collected and burned. Scientific caution becomes an operational rule that can protect wildlife as well as people.
A Victory Still Under Study

A Victory Still Under Study
No final biochemical answer
The emergency ends before researchers identify the unknown compound’s composition. The suspected source remains a theory, even though it helps explain the danger responders observed.
Prevention without certainty
Authorities have removed known nests and carcasses, but the scientific record is unfinished. The campaign demonstrates that ecological safeguards may be necessary before every mechanism is understood.
