Where
seen? This colony of bumpy animals is commonly seen on
some of our Northern shores, but often overlooked as it resembles
a plant. It grows on large boulders, jetty pillings and other hard
surfaces.
Features: 5-8cm long. The colony
comprises a cluster of sparsely branched stems, forming short bushes
or bushy fringes on hard surfaces. Each stem has large polyps in capsules
(about 1cm long) regularly arranged along the length. Colours seen
include white, beige and bright orange. The colony is often overgrown
with encrusting sponges and ascidians.
Sometimes mistaken for a sea
fan (Order Gorgonacea) or a hydroid
(Order Hydrozoa). |
