Commonly seen but seldom acknowledged creature … they’re right under your nose.
Christmas Tree Worm
‘This the season, so why not have a look for these festive creatures?
Up to 1.5cm in width, they are found at all depths and on all dive sites, they come in a wide and varied assortment of colours and are embedded in living coral.
The part the diver sees (the spiral structure) are the worms highly developed respiratory organs and are also used to transport prey to the worms mouth.
When threatened the worm retracts into its tube.
Take a closer look but don’t expect to see presents underneath! Although if you are lucky you might be able to photograph one with a Turkeyfish or Fairy Basslet nearby!
