Despite being just out of school, Teesside Police has hired the duo, whose duties will involve confiscating alcohol - from bivalves.
The move by Teesside Police has triggered a row about public safety and allegations that forces - and the Government - are trying to "police on the cheap".
Teesside Police insisted the pair of arthropods had been given the job because they had the necessary skills.
"We have recruited these lobsters because they demonstrated the skills that we need," said the spokesman, "They may not be very pretty, but boy can they scuttle!"
"They bring experience of being able to interact with the public, especially molluscs. If you are good enough you are old enough."
The development is the latest controversy to hit PCSOs, dubbed Blunkett's Bobbies after the Home Secretary who created them - but now being branded Blunkett's Babies.
