Common name: Green-leaf worm

General information

The Green Polychaete, also known as the Green Paddle Worm, is a species of marine polychaete worm belonging to the family Phyllodocidae. Eulalia viridis is known for its vibrant green coloration, which is derived from the chlorophyll pigments within the algae it consumes. This worm is an active predator and scavenger, often seen moving swiftly through the substrate in search of food.

Care

In the aquarium, Eulalia viridis requires a well-established system with a sandy or muddy substrate that allows for burrowing. They are beneficial detritivores, helping to clean up excess food and waste. However, care should be taken as they can prey on small invertebrates or sessile organisms if not well-fed.

Reproduction

Green Polychaetes are capable of both sexual and asexual reproduction. In an aquarium setting, they may reproduce asexually by fragmentation, which can help maintain their population. Sexual reproduction involves the release of gametes into the water column, but this is less commonly observed in captivity.

Habitat

Eulalia viridis is found in a variety of marine environments, from intertidal zones to subtidal areas, often within algal mats or beneath stones. They are widespread across the Northeast Atlantic, from the Arctic down to the Mediterranean Sea.
