The segments of the thallus are connected by narrow constrictions, giving the algae a jointed appearance. The thalli of Lomentaria are typically reddish-brown in color, but they can also be greenish or purplish.
Environments
Lomentaria species are found in a variety of marine environments, including rocky shores, tide pools, and deeper water. They prefer cool, temperate waters, and are often found in areas with strong currents. Lomentaria species are typically found attached to rocks, shells, and other substrates, but they can also be found growing on other algae.
