Even under the sea we have Christmas Trees.
Christmas tree worms (Spirobranchus giganteus) are Christmas tree-shaped serpulid tube-dwelling worms with magnificent twin spirals of plumes used for feeding and respiration. They come in many colors including orange, yellow, blue, and white and, though they are small with an average 3.8 cm in span, they are easily spotted due to their shape, beauty, and color. Christmas tree worms are very sensitive to disturbances and will rapidly retract into their burrows at the slightest touch or passing shadow. They typically re-emerge a minute later, very slowly, to test the water before fully extending their plumes.
Some species can be found in Anilao, Batangas, Philippines.
Happy Holidays everyone.
