Distribution data supplied by the Ocean Biogeographic Information System (OBIS). To interrogate UK data visit the NBN Atlas.

Summary

Description

Parazoanthus axinellae is a colonial anemone. The polyps are up 1.5 cm tall, 0.5 cm in diameter and yellow in colour. The anemone has 26-34 moderate to long tapering tentacles which are bright yellow in colour and arranged into 2 cycles. The column is often encrusted with sand granules or sponge spicules.

Recorded distribution in Britain and Ireland

Parazoanthus axinellae has been recorded on the south west and west coasts of the British Isles.

Global distribution

Parazoanthus axinellae has been recorded around southwest Europe to the Mediterranean.

Habitat

Parazoanthus axinellae is usually found attached to organic substrata including sponges, shells and worm tubes. It is also found on rocks. Parazoanthus axinellae is found from the shallow sublittoral offshore to about 100 m.

Depth range

6-100m
