BALI, INDONESIA-These unique photos capture the moment a boy has his teeth picked clean by amazing underwater shrimp.

These fascinating creatures spend their lives diving inside the mouths of fish to remove the parasites that lurk there.

Russell Laman imitated the behaviour of the surrounding fish swarm to entice the cleaner shrimp into his mouth whilst snorkelling with his father Tim Laman in Bali, Indonesia. The 13-year-old queued with the waiting fish and then opened his mouth when the shrimps came near.

The shrimp then incredibly started to clean Russell's mouth and remove food from between the boys teeth whilst Tim took photographs.  Russell Laman, from Lexington, Massachusetts, said: ‘It felt like tiny little dentists picking away at my teeth and scuttling around my mouth, it tickled a little but not too badly.

‘I had watched fish getting cleaned at cleaning stations before and decided to try it out myself. ‘I thought it would be really cool to experience shrimp in my mouth first hand.  ‘It is a large part of the ecosystem underwater and many fish rely on the shrimp so I decided to rely on them as well.’

Father and son discovered the fish 'cleaning station' where the shrimp wait for customers, in a beautiful outcrop of sponges growing from some rocks. The area was loaded with cleaner shrimp and surrounded by hoards of fish.
