Have you ever seen or just heard the name of a "Christmas tree worm?"

For some people, it must be foreign to hear Christmas tree worms. It turns out that Christmas tree worms really do exist, at first glance these worms really resemble a Christmas tree. Unlike the usual worms, Christmas tree worms only live and breed on the ocean floor.

Reported by Amusing Planet, the Spirobrachus giganteus worm lives on the seabed with the characteristics of having hairs arranged in a spiral on its body, almost like a pipe. The bristles consist of thin, hair-like tendrils, usually called radioles, which arise from the nerve centers of the Christmas tree worms that serve to help catch their food.

Their diet consists of microscopic plants or phytoplankton floating in the water. The bristles of this worm also function as a respiratory organ. Uniquely, this Christmas tree worm is no more than 4 cm. The attraction of this worm can be seen from its various colors ranging from blue, white, orange, and yellow, very beautiful to the eye.

This type of worm is not very mobile and not very aggressive. Once they find a place on the coral reef, the Christmas tree worms will make holes in the coral reef and stay there for the rest of their lives.

Christmas tree worms are also very sensitive to outside disturbances and will quickly enter the hole if they detect a passing touch.

According to data from the World Register of Marine Species, this worm is a species whose population is spreading, so that until now there has been no effort to preserve this marine animal. The habitat of Christmas tree worms is the tropical sea, and can be found from the Caribbean to the Indian Ocean.
