Where
seen? This colony of tiny animals is commonly seen on some
of our shores, but is often overlooked. The colony grows on stones
and hard surfaces, including litter on the shores!
Features: Colony about 10-15cm,
sometimes much larger. Polyps about 1cm in diameter, on stalks about
1cm long emerging from low to tubular mounds (calyces). The eight
skinny tentacles have short thin branches in 1 row on both sides of
each tentacle. Side branches brownish, oral disk and main tentacles
white, greenish or bluish. The polyps emerge from a purplish magenta
common membrane that encrusts hard surfaces. The polyps don't pulsate
and can slowly retract completely leaving a bumpy purple common tissue. |
