Codium fragile fragile grows in high densities and can dominate canopy species in infralittoral rocky reef communities. Identification: Codium fragile, or "Dead Man's Fingers" is a seaweed named for its dark green color and soft, felt-like texture.It has earned the common name "Dead Man's Fingers" or "Green Sea Fingers" for its swollen, finger-shaped branches that float in the water, or … Habitat & Range This species is found in the lower intertidal to subtidal, on rocky open coastlines. tomentosoides were obtained with temperatures ranging from 18 to 24 °C and a long-day … tomentosoides (Van Goor) Silva collected from New Zealand habitats. It is native to Asia and has been introduced around the globe, including North America, South America, Greenland, Europe, Africa, Australia and New Zealand. tomentosoides tolerates large variations in salinity and temperature, enabling it to colonise a wide range of environments. We have employed a combination of plastid microsatellite markers and DNA sequence data from three regions of the plastid genome to trace the invasive history of the green alga Codium fragile ssp. tomentosoides in the Gulf of Maine, both male and female gametes are produced in the same sex organ. fragile), female and male gametangia occur on separate plants. Codium fragile is a large, dark green macroalga with one to several, thick upright branches arising from a broad, spongy basal disc attached to the substrata. Blue markers: specimen records Yellow marker: type locality, if present Red markers: endpoints of range from literature View map from the Consortium of Pacific Northwest Herbaria. Depth range based on 44 specimens in 3 taxa. Natural Environment: Inhabits intertidal areas/tidepools and seen attached to coral rubble and broken shell material where it forms a mass of dark green spongy to the touch branches that are repeatedly forked. tomentosoides (van Goor) Silva were monitored at 3 locations in Rhode Island. californicum. Occurs in: coastland, estuarine habitats, marine habitats. "Tomentosoides" and "Membranipora membranacea" in the Gulf of Maine. Codium fragile is a conspicuous green alga with thick, spongy, and finger-like fronds, giving rise to its common name ‘Dead Man’s Fingers’. The geographic distribution of Codium within New Zealand is correlated with L. B. Moore's (1949) algal provinces. Species Codium geppiorum O. C. Schmidt, 1923. Codium, genus of about 50 species of marine green algae (family Codiaceae) usually found in deep pools along rocky coasts. Chavanich S., Harris L.G., Je J-G & Kang R-S (2006): Distribution pattern of the green alga Codium fragile (Suringar) Hariot, 1889 in its native range, Korea, Aquatic invasions, Volume 1, Issue 3: 99-108 [as Codium fragile] The density, cover and size (length, branching and weight) of annual erect thalli of Codium was enhanced in sheltered conditions, resulting in the monopolization of landward low‐shore habitats of breakwaters. Codium fragile. Range: Indo-West Pacific Ocean: Maldives east to Papua New Guinea, north to Taiwan, south to Hawaii, Australia, and New Zealand. Species Codium hubbsii Dawson, 1950.

Codium fragile: Morphological and molecular variation present in native and introduced subspecies in Auckland ResearchSpace/Manakin Repository Female gametes are twice the diameter of male gametes and outnumber them 6:1. In both species the ability to reduce acetylene is invariably associated with the presence of a heterocystous blue-green alga, Calothrix sp., epiphytic or embedded in the Codium thallus. Species Codium geppiorum O. C. Schmidt, 1923. MATERIALS AND METHODS Collection and maintenance of plant material Young (up to five dichotomies) and old (up to eight dichotomies) specimens of C. fragile were collected from intertidal rock pools at Bembridge, Isle of Wight in November 1979. Extremely low levels of genetic variation were detected, with only four haplotypes present in the species’ native range in Japan and only two of these found in introduced populations. The cylindrical branches are dichotomously branched and arise from a juvenile phase having both prostrate and erect branches. 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.

Codium fragile fragile grows in high densities and can dominate canopy species in infralittoral rocky reef communities. Identification: Codium fragile, or "Dead Man's Fingers" is a seaweed named for its dark green color and soft, felt-like texture.It has earned the common name "Dead Man's Fingers" or "Green Sea Fingers" for its swollen, finger-shaped branches that float in the water, or … Habitat & Range This species is found in the lower intertidal to subtidal, on rocky open coastlines. tomentosoides were obtained with temperatures ranging from 18 to 24 °C and a long-day … tomentosoides (Van Goor) Silva collected from New Zealand habitats. It is native to Asia and has been introduced around the globe, including North America, South America, Greenland, Europe, Africa, Australia and New Zealand. tomentosoides tolerates large variations in salinity and temperature, enabling it to colonise a wide range of environments. We have employed a combination of plastid microsatellite markers and DNA sequence data from three regions of the plastid genome to trace the invasive history of the green alga Codium fragile ssp. tomentosoides in the Gulf of Maine, both male and female gametes are produced in the same sex organ. fragile), female and male gametangia occur on separate plants. Codium fragile is a large, dark green macroalga with one to several, thick upright branches arising from a broad, spongy basal disc attached to the substrata. Blue markers: specimen records Yellow marker: type locality, if present Red markers: endpoints of range from literature View map from the Consortium of Pacific Northwest Herbaria. Depth range based on 44 specimens in 3 taxa. Natural Environment: Inhabits intertidal areas/tidepools and seen attached to coral rubble and broken shell material where it forms a mass of dark green spongy to the touch branches that are repeatedly forked. tomentosoides (van Goor) Silva were monitored at 3 locations in Rhode Island. californicum. Occurs in: coastland, estuarine habitats, marine habitats. "Tomentosoides" and "Membranipora membranacea" in the Gulf of Maine. Codium fragile is a conspicuous green alga with thick, spongy, and finger-like fronds, giving rise to its common name ‘Dead Man’s Fingers’. The geographic distribution of Codium within New Zealand is correlated with L. B. Moore's (1949) algal provinces. Species Codium geppiorum O. C. Schmidt, 1923. Codium, genus of about 50 species of marine green algae (family Codiaceae) usually found in deep pools along rocky coasts.

Codium fragile: Morphological and molecular variation present in native and introduced subspecies in Auckland ResearchSpace/Manakin Repository Female gametes are twice the diameter of male gametes and outnumber them 6:1. In both species the ability to reduce acetylene is invariably associated with the presence of a heterocystous blue-green alga, Calothrix sp., epiphytic or embedded in the Codium thallus. Species Codium geppiorum O. C. Schmidt, 1923. MATERIALS AND METHODS Collection and maintenance of plant material Young (up to five dichotomies) and old (up to eight dichotomies) specimens of C. fragile were collected from intertidal rock pools at Bembridge, Isle of Wight in November 1979. Extremely low levels of genetic variation were detected, with only four haplotypes present in the species’ native range in Japan and only two of these found in introduced populations. The cylindrical branches are dichotomously branched and arise from a juvenile phase having both prostrate and erect branches. 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.
