A delicate fenestrate bryozoan that grew as a slender central stem with side branches arranged in one plane, giving the colony the look of a small feather.

Colonies are fragile and almost always found as short broken lengths rather than complete fronds.

Note on the identification

Catalogued on the old site under Coral. It is a bryozoan, not a coral — a different phylum entirely.
