Ulva compressa
Ulva compressa, commonly known as baitweed in Australia, is a marine species of green algae in the family Ulvaceae. It has worldwide distribution. The hair-like thallus are very fine but can grow to a length of approx. 20 cms. Note the small crab and insects give this spotting a sense of scale. This species grows into two shapes: a ruffled form and cylindrical form, which look very different. It sometimes grows as an epiphyte on seagrasses and other algae. (see 2nd reference) This is an edible species.
This spotting was in the intertidal zone of the rock platform below Broken Head, near The Haven at Terrigal Beach on the NSW Central Coast.
