Scaberia agardhii

Scaberia agardhii

Scaberia agardhii is a pale brown, branching, beaded seaweed found on rocks in South Africa, Australia and New Zealand.
Brown Algae (Scaberia agardhii) This sturdy seaweed stood out amongst other leafy and filamentous sea weeds on the beach. The "green-pepper corn" studded branches looked very interesting and it took me several months to find out what it was and a little more about it. 
Branches had scaly segments and a few rounded structures which are probably receptacles that house sex organs. Growth is said to be initiated by a three-sided apical cell.
This species is endemic to Southern Australia. Found in shallow sheltered and moderately exposed sea beds in temperate Australian waters. Australia,Geotagged,Scaberia agardhii,Summer,brown algae
