Despite its appearance, kelp is not a plant but a stramenopile (a group containing many protists). [4] Kelp grow from stalks close together in very dense areas like forests under shallow temperate and Arctic oceans. [3] They were previously thought to have appeared in the Miocene, 5 to 23 million years ago based on fossils from California. [5]
The range is the northeast Atlantic Ocean (including the Baltic and North Seas), from the North Cape, Norway and the Kola Peninsula south to central Portugal. [6] [7]Laminaria hyperborea grows on rocks in the sublittoral zone at depths down to about 10 m (35 ft) in turbid waters and down to 30 m (100 ft) where the water is clear. [8]
Membranipora membranacea colonies consist of individual organisms called zooids, each with a chitinous exoskeleton which is secreted by the epidermis. [6] This exoskeleton, hardened with calcium carbonate, is known as the zooecium, which not only serves to protect the internal structures of the organism, but also keeps the individual permanently attached to the substrate and neighboring zooids ...

The central band is dimpled while the margins are smoother with a wavy edge, this is to cause greater water movement around the blades to aid in gas exchange.
