description Desmarestia aculeata Overview
Desmarestia aculeata is a brown alga recorded from the North Atlantic and North Pacific. Its cells store sulfuric acid in vacuoles, an unusual chemical defense that can make the alga strongly acidic when the tissue is damaged. Ruptured cells may bleach or injure other algae collected with it, so the species is notable both for its ecology and for the handling problems created by its chemistry.
help Desmarestia aculeata FAQ
What is unusual about Desmarestia aculeata?
Desmarestia aculeata stores sulfuric acid in cellular vacuoles. When its tissue is damaged, the released acid can make the alga strongly acidic.
Where is Desmarestia aculeata found?
It has been recorded in both the North Atlantic and North Pacific. It is a brown alga associated with marine habitats in those regions.
Can Desmarestia aculeata damage other algae?
Yes. Ruptured cells may release acidic contents that can bleach or injure nearby algae. This chemical defense makes damaged tissue particularly important to handle with care.
Why does Desmarestia aculeata contain sulfuric acid?
The acid is stored in vacuoles and functions as an unusual chemical defense. Damage to the tissue can release it and create strongly acidic conditions around the alga.
