The Colpomenia sinuosa is a ball-shaped, hollow alga, rigid and smooth. The thallus is often covered with a shiny mucousy layer.
Cystoseira (as well as sargassum) are the largest algae in the Eastern Mediterranean. The Cystoseira has a developed holdfast that connects it to the substrate...
The Cystoseira compressa is a brown bushy alga, with a holdfast comprised of a single unit (compact). It is unbranched and several short stipes emanate from it. The alga has two forms of branches: som
A small, delicate, rounded species. The toful (the condensation at the base of the central branches) is partial, delicate, smooth and connected to the stipe.
The species is much smaller than the Cystoseira compressa. Its branches are cylindrical or slightly flattened (the flattened branches have a delicate central vein).
The Cystoseira schiffneri generally resembles the Cystoseira compressa in shape. The central axis and central branches are covered with irregular warts and projections.
The Cystoseira spinosa has a single compact, unbranched holdfast. It has a short stipe split into several branches.
The Dictyopteris membranacea is an erect brown alga that is easily identified. It is made of elongated stipes of thin membranous thalli at the centre of which a central axis runs prominently.
The flat thallus of the alga is branched dichotomously several times at an angle of 15-30 degrees. Most branches are flat and slightly rounded at the edges.
The Dictyota fasciola is a flat alga that resembles other species of Dictyota. The edges of the thallus are rounded, and the alga stands erect in the water.
The Ectocarpus is a tiny alga that can be examined only through a microscope. Its thallus is comprised of elongated cells that form split filaments.
The Hydroclathrus clathratus resembles an oval ball of mesh. Holes in the mesh tend towards round, but they are irregular and unequal in size.
The Lobophora has a flattened thallus shaped like a fan. It attaches to rocks loosely and to the substrate through numerous rhizoids.
The mature plant resembles a bonnet or a fan, sometimes split into lobes that also resemble a fan.
The Petalonia resembles a cluster of brown strands. The strands are narrow at the base and edges, and emanate from a common base.
