Desmarestia aculeata

The morphology of this phaeophyte varies with the season. Some forms are covered with many short delicate hairs. The color, once pressed and dried, can vary from light brown to green. The specimen seen here was collected and pressed by Mr. Alex Frost, scientist/artist. You too can collect and press marine algae (instructions, tips, recommended collection sites). Beware when you collect this species. The cells of Desmarestia contain sulfate ions. When these cells are disrupted, these ions interact with seawater to produce sulfuric acid. Because of this, Desmarestis is protected from being eaten by most creatures. When you go collecting, you should always keep Desmarestia separated from your other specimens, otherwise they will be damaged by the sulfuric acid before you have a chance to press them.
