Whilst diving during the day a co-worker noticed that a small Turbinaria 
frondens was releasing from its polyps material which did not appear to be 
mucus and it was settling onto the colony and adjacent area.  The material 
released from the polyps had a green tinge to it and remained on the colony 
until it was washed away by water movement.  I have attached a couple of 
image links that show the excretion on the colony and shows the material 
being released from the polyps. If anyone has seen this before and knows 
what it is and why there is so much could you reply.
