Very special thanks for the first two photos of Serpula columbiana from USA.

In the past the species found on the Pacific Coast of North America was referred to as Serpula vermicularis. They have since been found to be taxonomically distinct from this species and are now referred to as Serpula columbiana.

Size range: 2 or 3 inches (5-8 cm) long, tubes up to 4 inches (10 cm) long.

Identifying features: Calcareous tube worms have bright colors varying from orange to red with white bands. The most indicative feature of these organisms is their feathery flower-like crown arranged in two spiraled-semicircles. The crown consists of branched tentacles known as cirri or radioles and a trumpet-shaped operculum. The tentacles reorganize into a funnel-shaped stopper when the crown is withdrawn. The animal lives in white calcified tubes. These tubes can be up to 10 cm long and about 2mm in diameter. Coils of white tubes are often seen fastened to hard substrates.

Habitat: This species commonly attaches to rocks, shells, floats, piers, stones, and algae such as Fucus. They live in tide pools and low intertidal zone to 100 m (330 feet) deep. These worms tend to stay away from Nereocystis luetkeana, a type of kelp. These kelps contain carbon monoxide in their pneumatocysts, which is highly toxic to Serpula columbiana. The organism can be found in various places from Alaska to Northern California. They are also seen in South and West of Britain, West of Scotland, Pacific, Atlantic, and Indian Oceans.

Food: Members of Serpula columbiana are filter feeders that feed on tiny microscopic organisms and detrital particles. When feeding, the animal extends the radioles from the anterior of its tube. Chains of cilia on these tentacles drift food particles towards the mouth.

Predators: Some of Serpula columbiana's predators are the wrasse Ctenolabrus rupestris and Crenilabrus melops, the sea stars Asterias arbens and Pisaster ochraceus, and the urchins E. esculentus and P. miliaris. When the worm is threatened, it reacts instantly by withdrawing into its tube and closing its entrance-way with its operculum.

Life cycle: Serpula columbiana has separate sexes and goes through long breeding season occurring in summer. The operculum functions as a brood pouch in the species' reproduction. Its reproduction includes a larval swimming phase. When removed from tubes, the animal releases gametes that develop into a trochophore larva. Prototroch, metatroch and other structures of the larva are visible after one week. A long apical tuft and a stomach are seen three days later. After two weeks, the larva has left and right ocelli (simple eyes) and chaetae (bristle made of chitin). After four weeks, the head grows farther from the body, and the ocelli move closer to each other. In addition, radiole buds of the larvae are developed. The radiole buds will eventually become adult feeding structures and respiratory organs. As larvae develop into juveniles, they will choose a location to settle.
