Common name: Bristle Worm

General information

Bristle worms, specifically Phyllodoce lamelligera, are a type of segmented worm found in marine environments. They are part of the polychaete family, which is known for its bristles that protrude from the sides of the body. These bristles can be irritating to human skin, so caution is advised when handling them. Despite their somewhat fearsome appearance, bristle worms are actually beneficial scavengers in the reef aquarium, consuming detritus and leftover food.

Care

In the aquarium, Phyllodoce lamelligera does not require specific care as they often hitchhike on live rock or coral fragments. They thrive in a variety of conditions, but it's important to maintain good water quality to prevent overpopulation. If their numbers become too high, they can be manually removed or controlled with natural predators.

Reproduction

Bristle worms are capable of both sexual and asexual reproduction. In the aquarium, they often reproduce by releasing eggs and sperm into the water column, where fertilization occurs. The larvae then settle and grow into new worms. Asexual reproduction can occur through fragmentation, where a piece of the worm breaks off and regenerates into a new individual.

Habitat

Phyllodoce lamelligera is found in a variety of marine habitats, including coral reefs, rocky substrates, and sandy bottoms. They are adaptable and can be found at various depths, often burrowing into the substrate or hiding in crevices during the day.
