y-branch brown seaweed Dictyota dichotoma* Family Dictyotaceae updated Feb 13 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 roundedtips. 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. Human uses: Strap brown seaweed is eaten by people and used as animal feed, medicine for its antibacterial properties. D. dichotoma is also used to make beer, frozen food, fruit juices, ice cream, jellies, in meat and flavour sauces, milk shakes, pastries and salad dressings. Extracts from it are also used in industry as emulsifiers, gelling agents, stabilisers. |
