Brown Algae's & Weed's
The Phaeophyceae or brown algae (singular: alga), is a large group of mostly marine multicellular algae, including many seaweeds of colder Northern Hemisphere waters. They play an important role in marine environments, both as food and for the habitats they form. For instance Macrocystis, a kelp of the order Laminariales, may reach 60 m in length, and forms prominent underwater forests. Another example is Sargassum, which creates unique habitats in the tropical waters of the Sargasso Sea. Many brown algae, such as members of the order Fucales, commonly grow along rocky seashores. Some members of the class are used as food for humans... (Wikipedia)

Brown Fingerweed
(Scaberia agardhii)
Photographed at Point Peron.
Brown Forkweed
(Dictyota dichotoma)
Photographed at Jervoise Bay, Woodmans Point.
The irridescent blue covering is quite beautiful and suprising when you see it for the first time.
Common Kelp
(Ecklonia radiata)
Photographed at Point Peron.
The Common Kelp has coating of fine thorns, that if you are not careful can give you a sharp little sting, like getting a needle in your finger, this can be quite irritable for a couple of days.
Elegant Padina
(Padina eleganas)
Photographed at the Camilla Wreck.
Possibly Fanweed
(Zonaria turneriana)
I have seen a couple of different photographs of Fanweed that confirm these are indeed Fanweed, however I have also seen other photographs of Fanweeds that leave me a little confused and scratching my head.
Any clarification would be good.
Sinuous Ballweed (Colpomenia sinuosa)
or
Leatherweed (Leathesia difformis)
Apparrently the only difference between these two weeds is that one has a slimy mucous inside and you need to cut it open to find out which is which, so they are easily confused with each other.
I am going to guess Sinuous Ballweed...... ????
Possibly Sargassum Sp.
Photographed at Point Peron.
These are a very common sight at Point Peron, especially in the shallower parts, they are thick, dense and flowery.
They appear to be remarkably like Sargassum species, however I have not been able to find a clear representation in my books or online of which type as they all have similar characteristics.
