Saccorhiza polyschides, common name furbellow, is a large brown algae of the lower shore and is the largest seaweed found in Europe. [2]
Saccorhiza polyschides is a large and bulky seaweed growing to 2 - 4 metres long. The holdfast is a large, bulbous [3] hollow, knobbly structure. The stipe is long, tough, leathery and rigid and is several centimetres wide. Near the base the margin forms several broad, wavy frills. These ruffles tend to dissipate wave energy and lessen the likelihood that it will be torn from the rock. The frond is digitate with about eight large flat lobes and may be massive. The lack of a midrib distinguishes it from Alaria esculenta . [4] [5] It is an extremely fast growing species, growing annually from the base and becoming fully extended over the course of a few months. [6]
Saccorhiza polyschides is found on the lowest part of the shore. It can not tolerate desiccation and may be found in places where it is wetted by spray when uncovered by the retreating tide. It is often found in association with Laminaria hyperborea . [2]
Distribution including Europe: Ireland, Britain, Faroes, France, Greece, Helgoland, Isla de Alboran, Italy, Netherlands, Norway, Portugal, Scandinavia and Spain. [7]
Chondrus crispus—commonly called Irish moss or carrageen moss —is a species of red algae which grows abundantly along the rocky parts of the Atlantic coast of Europe and North America. In its fresh condition this protist is soft and cartilaginous, varying in color from a greenish-yellow, through red, to a dark purple or purplish-brown. The principal constituent is a mucilaginous body, made of the polysaccharide carrageenan, which constitutes 55% of its dry weight. The organism also consists of nearly 10% dry weight protein and about 15% dry weight mineral matter, and is rich in iodine and sulfur. When softened in water it has a sea-like odour and because of the abundant cell wall polysaccharides it will form a jelly when boiled, containing from 20 to 100 times its weight of water.
Phycology is the scientific study of algae. Also known as algology, phycology is a branch of life science.
Fucus vesiculosus, known by the common names bladder wrack, black tang, rockweed, bladder fucus, sea oak, cut weed, dyers fucus, red fucus and rock wrack, is a seaweed found on the coasts of the North Sea, the western Baltic Sea and the Atlantic and Pacific Oceans. It was the original source of iodine, discovered in 1811, and was used extensively to treat goitre, a swelling of the thyroid gland related to iodine deficiency.
The sea lettuces comprise the genus Ulva, a group of edible green algae that is widely distributed along the coasts of the world's oceans. The type species within the genus Ulva is Ulva lactuca, lactuca being Latin for "lettuce". The genus also includes the species previously classified under the genus Enteromorpha, the former members of which are known under the common name green nori.
Fucus is a genus of brown algae found in the intertidal zones of rocky seashores almost throughout the world.
Palmaria palmata, also called dulse, dillisk or dilsk, red dulse, sea lettuce flakes, or creathnach, is a red alga (Rhodophyta) previously referred to as Rhodymenia palmata. It grows on the northern coasts of the Atlantic and Pacific Oceans. It is a well-known snack food. In Iceland, where it is known as söl[ˈsœːl̥], it has been an important source of dietary fiber throughout the centuries.
Ascophyllum nodosum is a large, common cold water seaweed or brown alga (Phaeophyceae) in the family Fucaceae, being the only species in the genus Ascophyllum. It is a seaweed that only grows in the northern Atlantic Ocean, also known in localities as feamainn bhuí, rockweed, Norwegian kelp, knotted kelp, knotted wrack or egg wrack. It is common on the north-western coast of Europe including east Greenland and the north-eastern coast of North America, its range further south of these latitudes being limited by warmer ocean waters.
Alaria esculenta is an edible seaweed, also known as dabberlocks or badderlocks, or winged kelp. It is a traditional food along the coasts of the far north Atlantic Ocean. It may be eaten fresh or cooked in Greenland, Iceland, Scotland and Ireland. It is the only one of twelve species of Alaria to occur in both Ireland and in Great Britain.
Ulva lactuca, also known by the common name sea lettuce, is an edible green alga in the family Ulvaceae. It is the type species of the genus Ulva. A synonym is U. fenestrata, referring to its "windowed" or "holed" appearance.
Fucus serratus is a seaweed of the north Atlantic Ocean, known as toothed wrack or serrated wrack.
Patella pellucida, common name the blue-rayed limpet, is a species of small saltwater limpet, a marine gastropod mollusc in the family Patellidae, the true limpets.
Pelvetia canaliculata, the channelled wrack, is a very common brown alga (Phaeophyceae) found on the rocks of the upper shores of Europe. It is the only species remaining in the monotypic genus Pelvetia. In 1999, the other members of this genus were reclassified as Silvetia due to differences of oogonium structure and of nucleic acid sequences of the rDNA.
Corallina officinalis is a calcareous red seaweed which grows in the lower and mid-littoral zones on rocky shores.
Laminaria digitata is a large brown alga in the family Laminariaceae, also known by the common name oarweed. It is found in the sublittoral zone of the northern Atlantic Ocean.
Macrocystis pyrifera, commonly known as giant kelp or bladder kelp, is a species of kelp, and one of four species in the genus Macrocystis. Despite its appearance, it is not a plant; it is a heterokont. Giant kelp is common along the coast of the northeastern Pacific Ocean, from Baja California north to southeast Alaska, and is also found in the southern oceans near South America, South Africa, Australia, and New Zealand. Individual algae may grow to more than 45 metres long at a rate of as much as 60 cm (2 ft) per day. Giant kelp grows in dense stands known as kelp forests, which are home to many marine animals that depend on the algae for food or shelter. The primary commercial product obtained from giant kelp is alginate, but humans also harvest this species on a limited basis for use directly as food, as it is rich in iodine, potassium, and other minerals. It can be used in cooking in many of the ways other sea vegetables are used, and particularly serves to add flavor to bean dishes.
Codium fragile, known commonly as green sea fingers, dead man's fingers, felty fingers, forked felt-alga, stag seaweed, sponge seaweed, green sponge, green fleece, and oyster thief, is a species of seaweed in the family Codiaceae. It originates in the Pacific Ocean near Japan and has become an invasive species on the coasts of the Northern Atlantic Ocean.
Sycon ciliatum is a species of calcareous sponge belonging to the family Sycettidaephylum.
Chorda filum, commonly known as dead man's rope or sea lace among other names, is a species of brown algae in the genus Chorda. It is widespread in the temperate waters of the northern hemisphere. The species also has numerous other common names related to its physical appearance. Names include mermaid's tresses, cat's gut or sea-catgut, bootlace weed, sea-twine, and mermaid's fishing line.
Phyllariaceae is a family of brown algae in the order Tilopteridales.
Phyllariopsis purpurascens is a species of large brown algae, found in the subtidal zone of the Mediterranean Sea and the intertidal zone of Morocco, as observed by Lourenço et al. (2020). While it is functionally similar to kelp species, it is not in the order Laminariales.
