y-branch brown seaweed Dictyota sp.* Family Dictyotaceae updated Aug 11 Where seen? Forming a clump of blue-tinged y-shaped blades, this seaweed is sometimes seen on our Southern shores, on coral rubble. Features: Flat, strap-like structures about 0.5-1cm wide and 5-7cm long. Regular branching on the same plane, forming distinct y-shapes with rounded tips. It has no 'veins' down the middle of the blade. The outer edges of the blade has a pattern of fine bars that form alternating blocks of dark and light blue sometimes forming a 'chequered' pattern on the rest of the blade as well. Generally light brown, sometimes maroon with a bluish tinge. Entire seaweed often forms an overall ball-shape. These may be different species of Strap brown seaweeds (Dictyota sp.) that just happen to have a bluish tinge. |
