Spirobranchus cariniferus, commonly known as the blue tubeworm or spiny tubeworm, or by its Māori name toke pā, is a species of tube-building polychaete worm endemic to New Zealand.[1][2][3]
This species forms patchy, belt-like colonies of hard, white, triangular tubes, each containing a bright blue worm. These are cemented to the shaded side of rocks in the lower to mid-tidal zone. It may also inhabit hard objects such as dead shells and small stones. When submerged, it puts out a fan of dark-blue tentacles to feed, which it retracts during low tide.[1][2][4]
Individuals living in Dunedin's Otago Harbour are the only polychaetes known to host gregarine parasites. Little is known about their impact on the worms, but it is likely to be a negative one.[5]
