|Phylum||Cnidaria||Sea anemones, corals, sea firs & jellyfish|
|Recorded distribution in Britain and Ireland||The species has a sporadic distribution associated with areas of low salinity within estuaries and brackish lagoons.|
|Habitat information||This hydroid colonizes brackish waters of 2 -12 psu but, where salinity may rise, occasionally up to 35 psu. It is found in shallow depths, often in shade, on various hard substrata, submerged vegetation, and the shells of crabs and snails.|
|Description||A tall erect colony growing up to 10 cm high, branching occasionally from alternate sides and light horn to light brown in colour. Each branch is ringed at the base and has a terminal polyp. The polyps are white to pale pink and have 12 -16 long, colourless, extensile tentacles arranged irregularly on the surface of the polyp. The mouth is born on a conical but truncated proboscis. Each branch bears one to three pear-shaped reproductive bodies on short stalks. It produces a planula larvae but no free-living medusoid stage.|
