Giant Clam

 on 


One of more colourful members of the animal kingdom at the bottom of the Great Barrier Reef are Molluscs. In this particular photograph it is the Giant Clam. When closed they look grey and uninteresting, often rock like. When they open an amazing array of colours can be observed. It is actually quite surprising how colourful this strange animal really can be. I have seen them with deep red or orange lines or as shown in this photograph with electric green against deep blue and purple.

Divers need to be aware of the clam for one simple reason – they are very strong and close the massive shell very rapidly. This is not an aggressive move, quite the opposite the clam closes to protect itself. It is best to admire them without touching. And as always when diving we should be very vigilant where we place our hands, fins and equipment in general. Leaving zero impact on the environment is the best practice.
