Hazardous substances detected is the Thargod weapon after unshielded hits

that makes perfect sense, the message appeared as it eventually shredded my shields as my incompetent fighter pilot ignored the giant rage monster perusing us. once the substance was detected there was about 30 seconds before things started shutting down permanently.
This 'weapon' also makes sense with the capitol class wreckages, they are unshielded. the thargoid could wipe out all vitals and suffocate crew within a very small time limit.
As a theory, could this 'weapon' be some sort of nano-bot/ organism that goes through and nibbles vitals? A perfect weapon for dealing with ships.....
