Baird's Christmas Tree Worm (species)

Baird's Christmas Tree Worm, scientifically known as Spirobranchus giganteus, is a colorful marine creature found in tropical coral reefs. It has a unique spiral-shaped structure resembling a Christmas tree, which is actually made of soft, feather-like appendages that it uses for feeding and respiration. These worms burrow into coral, and when disturbed, they retract quickly into their tubes for protection. Known for their vibrant colors, they play a vital role in the reef ecosystem by contributing to nutrient cycling and providing habitat for other marine species, making them an essential part of underwater biodiversity.
