Recorded distribution in Britain and IrelandA northern species recorded south to Northumberland. Found in the Forth of Firth, Orkney and Shetland in Scotland.
Global distributionCircumpolar arctic to northern temperate. In western Europe, recorded from Portugal to the north of Scandinavia but in the more southerly of these latitudes probably confined to deeper water.
HabitatPresent on hard substrata, including shells, from shallow sublittoral and offshore to edge of continental shelf (2-800 m).
- Hydrothecae (protective cups around specialised feeding polyps) are present only on side branches.
- Hydrothecae are flask-shaped, in two or three alternating series, and entirely immersed in the branch.
- Gonothecae (protective cups surrounding specialised reproduction polyps) are oval and sharply tapered at the base.
