Splachnidium rugosum, the deadman's fingers or gummy weed, is a species of seaweed in New Zealand. [1] [2] [3]
A small seaweed that grows on rocks near the shore and in the intertidal zone, tubular, which is filled with a clear gooey substance.
Native to New Zealand, and known across the southern hemisphere, from Tristan da Cunha to South Africa to Australia. [4] [2]
Community scientists using the platform INaturalist have identified superficially morphologically similar specimens across the southern Hemisphere using user-uploaded photos. [1]
Intertidal zone.
Splachnidium is monotypic, containing only the species S. rugosum. [5]
Wakame(Undaria pinnatifida) is a species of kelp native to cold, temperate coasts of the northwest Pacific Ocean. As an edible seaweed, it has a subtly sweet, but distinctive and strong flavour and satiny texture. It is most often served in soups and salads.
Hormosira is a genus of seaweed in the family Hormosiraceae. It is monotypic, with a single species, Hormosira banksii, also known as Neptune's necklace, Neptune's pearls, sea grapes, or bubbleweed it is native to Australia and New Zealand.
The intertidal zone or foreshore is the area above water level at low tide and underwater at high tide; in other words, it is the part of the littoral zone within the tidal range. This area can include several types of habitats with various species of life, such as sea stars, sea urchins, and many species of coral with regional differences in biodiversity. Sometimes it is referred to as the littoral zone or seashore, although those can be defined as a wider region.
Veronica is the largest genus in the flowering plant family Plantaginaceae, with about 500 species. It was formerly classified in the family Scrophulariaceae. Common names include speedwell, bird's eye, and gypsyweed.
Porphyra is a genus of coldwater seaweeds that grow in cold, shallow seawater. More specifically, it belongs to red algae phylum of laver species, comprising approximately 70 species. It grows in the intertidal zone, typically between the upper intertidal zone and the splash zone in cold waters of temperate oceans. In East Asia, it is used to produce the sea vegetable products nori and gim. There are considered to be 60–70 species of Porphyra worldwide and seven around Britain and Ireland, where it has been traditionally used to produce edible sea vegetables on the Irish Sea coast. The species Porphyra purpurea has one of the largest plastid genomes known, with 251 genes.
Ozius truncatus, the reef crab or black finger crab is a crustacean of the family Oziidae, endemic to Australia. It is distributed across southern and south western Australia, including Western Australia, South Australia, Victoria and southern NSW. A similar species Ozius deplanatus is found in eastern Australia and New Zealand, and was historically known as Ozius truncatus. In Australia the distribution of truncatus and deplanatus overlaps. Differences between the two species include that in Ozius truncatus the epibranchial ridge is broken by a groove, and the carapace is a little wider in deplanatus. The carapace is up to nearly 60 mm across, and oval in shape, around 1.4 to 1.5 times as long as wide. Ozius truncatus lives in the intertidal zone, feeding on marine snails, limpets and other small invertebrates.
Colpomenia peregrina, sometimes referred to by its vernacular names oyster thief and bladder weed, is a species of brown seaweed.
Corallina officinalis is a calcareous red seaweed which grows in the lower and mid-littoral zones on rocky shores.
Durvillaea is a genus of large brown algae in the monotypic family Durvillaeaceae. All members of the genus are found in the southern hemisphere, including Australia, New Zealand, South America, and various subantarctic islands. Durvillaea, commonly known as southern bull kelps, occur on rocky, wave-exposed shorelines and provide a habitat for numerous intertidal organisms. Many species exhibit a honeycomb-like structure in their fronds that provides buoyancy, which allows individuals detached from substrates to raft alive at sea, permitting dispersal for hundreds of days over thousands of kilometres. Durvillaea species have been used for clothing, tools and as a food source by many indigenous cultures throughout the South Pacific, and they continue to play a prominent role in Chilean cuisine.
Durvillaea antarctica, also known as cochayuyo and rimurapa, is a large, robust species of southern bull kelp found on the coasts of Chile, southern New Zealand, and Macquarie Island. D. antarctica, an alga, does not have air bladders, but floats due to a unique honeycomb structure within the alga's blades, which also helps the kelp avoid being damaged by the strong waves.
Asparagopsis armata is a species of marine red algae, in the family Bonnemaisoniaceae. English name(s) include red harpoon weed. They are multicellular eukaryotic organisms. This species was first described in 1855 by Harvey, an Irish botanist who found the algae on the Western Australian coast. A. armata usually develops on infralittoral rocky bottoms around the seawater surface to around 40m of depth. Marine algae like A. armata are considered "autogenic ecosystem engineers" as they are at the very bottom of the food chain and control resource availability to other organisms in the ecosystem.
Mitra mitra, common name the episcopal miter, is a species of large predatory sea snail, a marine gastropod mollusk in the family Mitridae, the miters.
Ulva intestinalis is a green alga in the family Ulvaceae, known by the common names sea lettuce, green bait weed, gutweed, and grass kelp. Until they were reclassified by genetic work completed in the early 2000s, the tubular members of the sea lettuce genus Ulva were placed in the genus Enteromorpha.
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.
Ulva compressa is a species of seaweed in Ulvaceae family that can be found in North America, Mediterranean Sea, and throughout Africa and Australia.
Digitaria ciliaris is a species of grass known by the common names southern crabgrass, tropical finger-grass, tropical crabgrass or summer grass.
Sargassum johnsonii is a brown seaweed of the genus Sargassum that is endemic to the Three Kings Islands in New Zealand. It is sometimes called totara weed because of the resemblance to the foliage of the NZ native tree totara. Its scientific name derives from its discoverer, Magnus Earle Johnson, Three Kings Islands explorer and captain of the yacht Rosemary, who landed botanists on the islands on several occasions.
Desmarestia ligulata is a species of brown algae found worldwide. Its common names include color changer, Desmarest's flattened weed, and sea sorrel, though the last name can also refer to other species of Desmarestia.
Ischaemum rugosum, also known as saramollagrass, is a flowering plant belonging to the grass family Poaceae in the genus Ischaemum, and is native to tropical and temperate regions of Asia, growing in marshes and other wet habitats. It is a vigorous annual, and is an invasive species in South America and Madagascar. It reaches heights of up to 1 m and is primarily recognized by the ridged surface of its sessile spikelet’s lower glume. Despite its historic importance as fodder in Asia, the grass has become a major weed in mid-latitude rice paddies throughout Asia and South America.
Ulva Island-Te Wharawhara Marine Reserve is a marine reserve covering an area of 1,075 hectares south-west and north-east of Ulva Island, in the Paterson Inlet of New Zealand's Stewart Island. It was established in 2004 and is administered by the Department of Conservation.
