This blog contains photos, mainly taken during diving around Perth and other parts of Western Australia, with occasional other locations thrown in. This header photograph was taken during a trip to Sipadan Island off the coast of Borneo. It shows a Grey Reef Shark disappearing into the gloom, which drops to around 600 metres deep - I was at around 30 metres!!

Christmas Tree Worm - Spirobranchus giganteus
These cone shaped tube-dwelling worms (two here) live on coral and most of their bodies are in a hole bored into a live calcareous coral. The colourful spirals are their tentacles, which are used for feeding and respiration. The coloured part is only about 3-4 centimetres in size and they are retracted into the burrow at the slightest movement near them.
