Neptune’s necklace
Hormosira banksii
One of our most recognisable seaweeds, you can find Neptune’s necklace along the rocky shore and in mangrove estuaries. Widespread throughout Auckland this seaweed is characterised by strings of olive brown hollow beads. The beads help the seaweed float and stop it from drying out in the sun. Neptune’s necklace is native to New Zealand, and also Australia. Keep an eye out for Neptune’s necklace on your next rocky shore fossick.
