The colorful and unique Christmas Tree Worm, Spirobranchus giganteus, adds to the excitement of diving in tropical coral reefs all around the world. Their colorful plumes, always appearing as an identical pair, are used for both breathing and feeding. The plumes are covered with tiny hairs that trap food in the water and sweep it towards the animal’s mouth.

The Oriental Sweetlips, Plectorhinchus vittatus, lives in reefs in the Indian and Pacific Oceans, near Indonesia. They have rather puffy lips, hence the name. 😛
This species really looks different between its juvenile and adult form! Young sweetlips are rather speckled with dark splotches on a light background. Eventually, these markings morph to black and white stripes with yellow tail, fins, and face. The bright yellow shows the splotches of youth, although they are smaller overall, more like spots. Check out the links below the pic to find out more about this unique species of grunt fish.
