This attractive sea weed had a zig-zagging tough central stalk with small densely clustered bladder like blades, arising at points in the zig-zag. Some blades had a bifurcation. The whole body of the seaweed was a brownish green with dark brown tinges.
Said to grow in the low intertidal and shallow subtidal rocky reefs with moderate wave action, to depth of 10 m.
Spotted along the high tide mark on a sandy shore, along with other sea weeds - Western Port Bay
This pale reddish brown elongated sac-like structure with a club shaped tip and narrow base is part of a red seaweed which grows in a clump, attached to the sea floor by a discoid holdfast. The inside of the bladder appears to be filled with mucilage. This bladder was about 50 mm long.
This seaweed can grow up to 16 cms in length. The outer walls of sacs growing in rough waters are said to be thicker than those in calm waters. The secretory cells lining the inside of the sacs produce highly viscous mucilage.
Spotted along the high tide mark along with other sea weeds on a sandy beach - Western Port Bay.
Occur in Seagrass beds upto a depth of 20 mts.
Found trapped in a small pool of seawater at low tide on rocks.
These are very fast and always keen to remain in shadows.
About 9mm long; others in the area suggest high variability in colour and pattern.
