Codium bursa is a green marine algae of medium size.
Codium bursa is a marine alga growing to 30 cm across. It generally appears as a spongy sphere of utricles which at the surface form a cortex. It is composed of loosely packed filaments which at the surface form a cortex of utricles which are single celled bladder-like or club-shaped structures. [2] It has a velvety texture and is dark green in colour. The alga is attached by a holdfast of filaments. [3]
In the Atlantic from the Canary Islands to the British Isles, [4] where they perhaps are originating further south, since C. bursa is very persistent in drift. [4] In Ireland the most recent record was in 1977 from County Donegal. [5] also recorded from other countries in Europe. [3] In the Mediterranean often found accompanying the seagrass Posidonia oceanica and commonly found beachcast amongst leaves of Posidonia oceanica. [4]
Codium bursa grows sublittorally attached to rock to 10 m deep in the Atlantic Ocean [3] and up to 50 meters deep in the Mediterranean Sea. [4]
Ceramium is a genus of Ceramium algae. It is a large genus with at least 15 species in the British Isles.
Codium is a genus of edible green macroalgae under the order Bryopsidales. The genus name is derived from a Greek word that pertains to the soft texture of its thallus. One of the foremost experts on Codium taxonomy was Paul Claude Silva at the University of California, Berkeley. P.C. Silva was able to describe 36 species for the genus and in honor of his work on Codium, the species C. silvae was named after the late professor.
Atractophora hypnoides is a rare red alga (Rhodophyta) found in the British Isles, France and some Atlantic Islands and is the only species of the genus found in the British Isles. It is attached to the rock or other algae by a small basal disc and is much branched with downgrowing filaments which enclose the main branch or axis forming a cortex. Short filaments of limited growth radiate in whorls from the axis and frequently convert into hairs. The spreading filaments grow irregularly in a diffuse manner. Microscope examination is required for identification.
Schmitzia hiscockiana is a small, rare, red seaweed or marine alga of the phylum Rhodophyta or red algae. It was discovered and named in 1985.
Colpomenia peregrina, sometimes referred to by its vernacular names oyster thief and bladder weed, is a species of brown seaweed.
Halimeda tuna is a species of calcareous green seaweed in the order Bryopsidales. It is found on reefs in the Atlantic Ocean, the Indo-Pacific region and the Mediterranean Sea. Halimeda tuna is the type species of the genus Halimeda and the type locality is the Mediterranean Sea. The specific name "tuna" comes from the Taíno language, meaning "cactus" and referring to the resemblance of the thallus to the growth form of an Opuntia cactus.
Osmundea pinnatifida is a species of red alga known by the common name pepper dulse.
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, sea staghorn, 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.
Codium tomentosum is a species of green seaweed in the family Codiaceae. Its common names include velvet horn and spongeweed.
Chaetomorpha linum is a species of green algae in the family Cladophoraceae.
Polysiphonia denudata is a small red alga, Rhodophyta, growing as tufts up to 20 cm long without a main branch axis.
Polysiphonia elongata is a small red marine algae in the Rhodophyta.
Melanothamnus harveyi, Harvey's siphon weed, is a small marine red alga in the division of Rhodophyta.
Codium arabicum, commonly known as green sea cushion, is a species of seaweed in the Codiaceae family.
Vertebrata fruticulosa(Boergeseniella fruticulosa Kylin) is a small marine alga in the Division Rhodophyta.
Ceramium botryocarpum is a small red marine alga in the Division Rhodophyta.
Phyllophora crispa is a medium-sized fleshy, marine red alga. This alga forms dense mats of up to 15 cm thickness, which influence environmental factors, thus creating habitat for several associated organisms.
Phyllophora pseudoceranoides, the stalked leaf bearer, is a small marine red alga.
Phyllophora sicula, the hand leaf bearer, is a small red marine alga.
Zanardinia is a monotypic genus of seaweed in the brown algae. The only species, Zanardinia typus, commonly known as penny weed, is native to the northeastern Atlantic Ocean and the Mediterranean Sea.
