Seychelles Giant Millipede
The Seychelles giant millipede (''Sechelleptus seychellarum'') is a species of millipede endemic to Seychelles. The species has been listed as Endangered on the IUCN Red List. The species inhabits 14 islands within the Seychelles, with an extent of occurrence of , and occupancy area of . The species is found to have a higher density in elevated areas with a presence of rock coverage, and use granite rock crevices, fallen logs, and other rotting wood debris as diurnal refuges in forested habitats. The species is threatened by the introduction and spread of the non native Bamboo plant ''Bambusa vulgaris,'' whose presence is associated with lower population density within the species. The leaf litter of ''Bambusa vulgaris'' can also outnumber the leaf litter of native flora, which the species feeds on, creating a lack of suitable food resources for the species. In terms of diet, the species prefers to feed on the softer freshly fallen leaf litter of species including ''Pisonia gra ...

Julien Desjardins
Julien François Desjardins (27 July 1799, Centre de Flacq – 18 April 1840, Paris) was a French zoologist, the son of Julien Jouan Desjardins (1766–1853) and Henriette Émilie Marcotte. He married Julie Renée Maréchal, his first cousin by his mother. He studied in Paris from 1822 to 1824 under Cuvier, and was influenced by Louis Jacques Thénard (1777–1857), Joseph Louis Gay-Lussac (1778–1850), Pierre André Latreille (1762–1833), René Desfontaines (1750–1831) and others. He embarked on a career in civil engineering, but soon realised that he should return to his original passion of natural history and studied at the Muséum d'Histoire Naturelle. With Charles Telfair, Wenceslas Bojer, and Jacques Delisse, Desjardins took part in founding the ' on 11 August 1829. He was the first secretary of this Society and editor of the publication ' until 1839, when he left for France to publish his observations. His premature death led to the acquisition of his manuscript by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Millipede
Millipedes (originating from the Latin , "thousand", and , "foot") are a group of arthropods that are characterised by having two pairs of jointed legs on most body segments; they are known scientifically as the class Diplopoda, the name derived from this feature. Each double-legged segment is a result of two single segments fused together. Most millipedes have very elongated cylindrical or flattened bodies with more than 20 segments, while pill millipedes are shorter and can roll into a tight ball. Although the name "millipede" derives from Latin for "thousand feet", no species was known to have 1,000 or more until the discovery in 2020 of '' Eumillipes persephone'', which can have over 1,300 legs. There are approximately 12,000 named species classified into 16 orders and around 140 families, making Diplopoda the largest class of myriapods, an arthropod group which also includes centipedes and other multi-legged creatures. Most millipedes are slow-moving detritivores, eat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seychelles
Seychelles (, ; ), officially the Republic of Seychelles (; Seychellois Creole: ), is an island country and archipelagic state consisting of 155 islands (as per the Constitution) in the Indian Ocean.

Seychelles was uninhabited prior to being encountered by Europeans in the 16th century. It faced competing French and British interests until it came under full British control in the early 19th century. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Species (IUCN Status)
Endangered species, as classified by the International Union for Conservation of Nature (IUCN), are species which have been categorized as very likely to become extinct in their known native ranges in the near future. On the IUCN Red List, endangered is the second-most severe conservation status for wild populations in the IUCN's schema after critically endangered. In 2012, the IUCN Red List featured 3,079 animal and 2,655 plant species as endangered worldwide. The figures for 1998 were 1,102 and 1,197 respectively. IUCN Red List The IUCN Red List is a list of species which have been assessed according to a system of assigning a global conservation status. According to the latest system used by the IUCN, a species can be "Data Deficient" (DD) species – species for which more data and assessment is required before their situation may be determined – as well species comprehensively assessed by the IUCN's species assessment process.

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...

Bambusa Vulgaris
''Bambusa vulgaris'', common bamboo, is an open-clump type bamboo species. It is native to Bangladesh, India, Sri Lanka, Southeast Asia, and to the province of Yunnan in southern China, but it has been widely cultivated in many other places and has become naturalized in several regions.Dieter Ohrnberger, ''The bamboos of the world'', pages 279–280, Elsevier, 1999, Among bamboo species, it is one of the largest and most easily recognized.''Biology Pamphlets'' (Volume 741), page 15, University of California, 1895D.

Pisonia Grandis
''Pisonia grandis'', the grand devil's-claws, is a species of flowering tree in the ''Bougainvillea'' family, Nyctaginaceae. Description The tree has broad, thin leaves, smooth bark and bears clusters of green sweet-smelling flowers that mature into sticky barbed seeds. Dispersal occurs when seeds stick to bird feathers. Vegetative reproduction frequently results when fallen branches sprout or basal shoots develop into new trees. Distribution ''Pisonia'' trees are distributed throughout the coral cays of the Indian and Pacific Oceans. The species often dominates mature coral cay vegetation, growing in dense, thick strands up to tall. ''Pisonia'' wood is rather weak and soft and decays rapidly when the trees fall. ''Pisonia'' forests are a common nesting site for seabirds. One of the best remaining ''Pisonia'' forests can be found on Palmyra Atoll. St. Pierre Island, Farquhar Group, was once covered by a ''Pisonia grandis'' forest. This forest disappeared after guano mini ...

Ficus
''Ficus'' ( or ) is a genus of about 850 species of woody trees, shrubs, vines, epiphytes and hemiepiphytes in the family (biology), family Moraceae. Collectively known as fig trees or figs, they are native throughout the tropics with a few species extending into the semi-warm temperate zone. The common fig (''F. carica'') is a temperate species native to southwest Asia and the Mediterranean region (from Afghanistan to Portugal), which has been widely cultivated from ancient times for its fruit, also referred to as figs. The fruit of most other species are also edible though they are usually of only local economic importance or eaten as bushfood. However, they are extremely important food resources for wildlife. Figs are also of considerable cultural importance throughout the tropics, both as objects of worship and for their many practical uses. Description ''Ficus'' is a pantropical genus of trees, shrubs, and vines occupying a wide variety of ecological niches; most a ...

Animals Described In 1834
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia (). With few exceptions, animals consume organic material, breathe oxygen, have myocytes and are able to move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million living animal species have been described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from to . They have complex ecologies and interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology, and the study of animal behaviour is known as ethology. The animal kingdom is divided into five major clades, namely Porifera, Ctenophora, Placozoa, Cni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arthropods Of Seychelles
Arthropods ( ) are invertebrates in the phylum Arthropoda. They possess an exoskeleton with a cuticle made of chitin, often mineralised with calcium carbonate, a body with differentiated ( metameric) segments, and paired jointed appendages. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. They form an extremely diverse group of up to ten million species. Haemolymph is the analogue of blood for most arthropods. An arthropod has an open circulatory system, with a body cavity called a haemocoel through which haemolymph circulates to the interior organs. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. They have ladder-like nervous systems, with paired ventral nerve cords running through all segments and forming paired ganglia in each segment. Their heads are formed by fusion of varying numbers of segments, and their brains are formed by fusion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
