Flat crunchy pom-pom red seaweed
Jania sp.*
Family Corallinaceae

updated Oct 15

Where seen? These pinkish crunchy flattened pom-poms are sometimes seen growing among living corals, or on rubble near living reefs, especially on our more remote Southern reefs.

Features: A usually rather flattened cluster (5-8cm) of many stiff, thick, cylindrical but flattened 'stems' that are branched along one plane forming Y-shapes. The tips with tiny white squarish 'caps'. The seaweed incorporates calcium carbonate making the 'stems' hard and brittle. It tends to grow flat against a hard surface, instead of forming a spherical bushy shape that sticks out. Colours pink or lilac.

May be confused with other pinkish seaweeds with a pom pom shape.
