Golden Kelp

Ecklonia radiata


Ecklonia radiata, commonly known as golden kelp, is a large brown to golden-brown seaweed up to 1.5 meters long. It has frilled fronds (lateral lamina) branching out from a flat wide stem (central lamina). The stem (stipe) is rounded and at the base has a holdfast that looks like the rooting part of a tree. This is not technically a root, but and anchoring device for the seaweed to hold steady on the rocks underwater. (from the Diego Bonetto website - see notes)


Spotted on a beach at Norah Head, on the NSW Central Coast. Grows in dense forests to depths of approximately 25m. Obviously washed ashore from a subtidal rocky reef by recent heavy seas.


Kelps are large brown algae seaweeds that make up the order Laminariales. There are about 30 different genera. Despite its appearance, kelp is not a plant; it is a heterokont.... NB: Golden kelp is an edible species and has considerable nutritional and medicinal properties. Here are a couple of very informative sites should you require further information....
