crunchy pom-pom red seaweed
These pinkish crunchy pom-poms are seen on both our Northern and
Southern shores, growing in clusters on rubble near living reefs,
densely on abandoned ropes, sometimes a tangled layer among seagrasses
forming a crunchy carpet that covers a large area. Smaller Jania
species may grow on seagrasses and seaweeds.
Features: A cluster (3-6cm)
of many stiff, slender, cylindrical 'stems' that are regularly branched.
The 'stem' tips often with a white rounded 'cap'. The cluster may
be a spherical bushy shape densely packed or rather loose. The seaweed
incorporates calcium carbonate making the 'stems' hard and brittle.
Colours pink, dark pink and purple.
