Home of a colony of worms cllaed Dodecaceria fewkesi. They are related to tube-building worms such as feather duster worms and calcareous tube worms.

The animals have black bodies with tentacles and gills at the mouth end. To make their rock colonies, each worm extracts calcium carbonate from seawater and deposits the material around its body as a tube. When many worms live on top of one another, the individual tubes fuse into one large mass. The larger colonies are usually found on reefs below low-tide level. Strong winter storms can shift boulders and dislodge the colonies, or the weight of large waves themselves can break them from the reef.

To make the rock colonies, one larval worm settles on a rock and draws calcium carbonate from the seawater to deposit around its body, thus forming a tube-shaped burrow. Once the “founding father” (or mother) worm reaches maturity, it divides in half. Two new worms are soon created from the new halves. As fission continues, the colony continues to grow, and new burrows are added to form one large, stony colony. The larger colonies are usually found on reefs below low-tide level.
