Description: An erect bryozoan that forms beautiful lace-like colonies. Usually white, pink, orange or brown in colour. Microscopic examination of features may be required to distinguish this species from other Reteporella.

Habitat: Attached to hard substrata.

Distribution: So far only recorded from Rathlin Island, Northern Ireland. Reteporella species can be hard to distinguish in the field so there are potentially more occurrences of this species.

Similar Species: There are several other species of Reteporella found in Britain and Ireland, microscopic examination of foramen and peristome may be required to distinguish.

Key Identification Features:

• Erect bryozoan, forming lace-like colonies.
• Microscopic examination or specialist identification required.
