Opacuincola Gretathunbergae
''Opacuincola gretathunbergae'' is a freshwater snail endemic to New Zealand. It is named after the climate activist Greta Thunberg. Distribution The snail was discovered in 2016 by a research team from the University of Greifswald, which spent two weeks surveying easily-accessible water bodies in the northern South Island, and discovered multiple new species of endemic snail. This species lives in small streams with shallow and slow-flowing water, and has so far been found in just one site. It was collected off stones and debris in a trickle of water beside Cobb Dam Road in the upper Tākaka River valley, within Kahurangi National Park. Description The sample of 20 collected had an average shell height of 2.35 mm and a height of 1.41 mm, and an aperture just under a millimetre wide. This species is closely related to ''Opacuincola ngatapuna,'' which has larger genitalia. Its well-developed eyes and pigmentation suggest it is a true crenobiont, one of a small number of spe ...

Freshwater Snail
Freshwater snails are gastropod mollusks which live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a shell, with very few exceptions. Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung (e.g. ''Ampullariidae''). Most feed on algae, but many are detritivores and some are filter feeders. According to a 2008 review of the taxonomy, there are about 4,000 species of freshwater gastropods (3,795–3,972). At least 33–38 independent lineages of gastropods have successfully colonized freshwater environments. It is not possible to quantify the exact number of these lineages yet, because they have yet to be clarified within the Cerit ...

Pristimantis Gretathunbergae
''Pristimantis gretathunbergae'', dubbed Greta Thunberg's rainfrog, is a species of frog in the family Strabomantidae, native to Panama. It is named in honor of Greta Thunberg, a climate activist. It lives in small pools of water held in bromeliads growing on the cloud forests of Mount Chucantí and other mountains of the Darién Gap The Darién Gap (, , es, Tapón del Darién , ) is a geographic region between the North and South American continents within Central America, consisting of a large watershed, forest, and mountains in Panama's Darién Province and the norther ..., and of central Panama.

Species Named After Greta Thunberg
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes in zoologica ...

Gastropods Of New Zealand
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Endangered Biota Of New Zealand
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Critter Of The Week
''Critter of the Week'' is a weekly RNZ National programme about endangered and neglected native plants and animals of New Zealand. Beginning in 2015, ''Critter of the Week'' is an approximately 15-minute discussion between Nicola Toki of the Department of Conservation and host Jesse Mulligan on an "uncharismatic and lovable" New Zealand species. The topic of spotlighting uncharismatic species was raised in an interview by Mulligan in April 2015, and the programme originated in a discussion between Mulligan and Toki about threatened bird conservation, in which she lamented a lack of attention and corporate funding for species such as the '' Smeagol'' gravel maggot. The first episode, airing 2 October 2015, featured the New Zealand bat fly. Each week's broadcast is supported by improving the Wikipedia article for the species in question. The show currently airs on Friday afternoons. In 2018, artist Giselle Clarkson designed t-shirts featuring a selection of species that had a ...

Greta Thunberg
Greta Tintin Eleonora Ernman Thunberg (; born 3 January 2003) is a Swedish environmental activist who is known for challenging world leaders to take immediate action for climate change mitigation. Thunberg's activism began when she persuaded her parents to adopt lifestyle choices that reduced their own carbon footprint. In August 2018, at age 15, she started spending her Fridays outside the Swedish Parliament to call for stronger action on climate change by holding up a sign reading ' (School strike for climate). Thunberg initially gained notice for her youth and her straightforward and blunt speaking manner, both in public and to political leaders and assemblies, in which she criticizes world leaders for their failure to take what she considers sufficient action to address the climate crisis. Soon other students engaged in similar protests in their own communities. Together they organized a school climate strike movement under the name ''Fridays for Future''. After Thun ...

Radula
The radula (, ; plural radulae or radulas) is an anatomical structure used by molluscs for feeding, sometimes compared to a tongue. It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters the esophagus. The radula is unique to the molluscs, and is found in every class of mollusc except the bivalves, which instead use cilia, waving filaments that bring minute organisms to the mouth. Within the gastropods, the radula is used in feeding by both herbivorous and carnivorous snails and slugs. The arrangement of teeth ( denticles) on the radular ribbon varies considerably from one group to another. In most of the more ancient lineages of gastropods, the radula is used to graze, by scraping diatoms and other microscopic algae off rock surfaces and other substrates. Predatory marine snails such as the Naticidae use the radula plus an acidic secretion to bore through the shell of other molluscs. Other predatory marine snails ...
