Whenever you are diving on sandy bottom,it is not hard to spot the goby sticking its head out from the burrow in the sand.
house.Like a bull dozer,gravel that drops into the burrow will be forcefully pushed back out again and again,
Do u know ,the shrimps are practically blind sensing their world with the antenae they have which it uses for comunication with the fish. linked to the tail of the goby fish,their world is limited to merely the immediate vicinity around their burrow which is like 1-2 sq meters.
then settle down very gently again on the sandy bottom, keeping a respectful distance so that you can see what happens next.quaint to watch.goby emerges 1st sticking its head out to see if the coast is clear,if it deems its safe ,no threat around,it gently taps the antennae of the shrimp then takes up position again on high alert while the shrimp repeats or continues where it left off cleaning the burrow,only mode of communication between them is tail and antennae.
