Hygraula Nitens
''Hygraula nitens'', the pond moth or Australian water moth, is a moth of the family Crambidae. It was described by Arthur Gardiner Butler in 1880. It is found in New Zealand and most of Australia, including Tasmania. The wingspan is about 25 mm. The caterpillars of this species live underwater. The filaments protruding from the body are not hairs but gills for breathing underwater. The larvae feed on ''Potamogeton crispus'' and ''Zostera'' species. They also feed on other alien macrophytes such as ''Hydrilla verticillata'', ''Lagarosiphon major'', and ''Ceratophyllum demersum ''Ceratophyllum demersum'', commonly known as hornwort, rigid hornwort, coontail, or coon's tail, is a species of ''Ceratophyllum''.

Aranda, Australian Capital Territory
Aranda () is a suburb in the district of Belconnen, in the Australian capital city of Canberra. Located at the western foot of Black Mountain and bounded on two sides by nature park, the suburb is characterised by its bush setting. During the planning and development of the suburb, a large proportion of large native trees – predominantly eucalypts – were left in place. The suburb derives its name from the Arrernte tribe of Central Australia, previously known as ''Arunta'', which means 'White Cockatoo'. The streets in Aranda are named after Aboriginal tribal groups from around Australia. The suburb comprises an area of 160ha and in 1967 was the first suburb in Belconnen to be settled. A small plaque at the Aranda District playing fields near the suspension bridge over Belconnen Way marks the settlement of the suburb as the first development in the Belconnen district. It reads: Location Aranda is located in the south east of Belconnen. It is bounded by Caswell Drive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acentropinae
Acentropinae is a fairly small subfamily of the lepidopteran family Crambidae, the crambid snout moths. Species of this subfamily are exclusively found in wetlands and aquatic habitats. Systematics In modern treatments, the former subfamily Nymphulinae is mostly treated as a tribe within Acentropinae. There are about 730 species in 78 genera. Only 13 species in 6 genera are found in Europe. *''Acentria'' Stephens, 1829 (= ''Acentropus'' J.

Lagarosiphon Major
''Lagarosiphon major'' is a Monocotyledon, monocotic aquatic plant native to Southern Africa. Common names include African elodea, curly waterweed, oxygen weed and South African oxygen weed. It is used as freshwater aquarium plant. It is an invasive species, invasive plant in some countries. In New Zealand it is listed on the National Pest Plant Accord and is classed as a noxious weed in the United States. ''Lagarosiphon Major'' was added to the European Union's List of invasive alien species of Union concern, List of Invasive Alien Species of Union concern on 3 August 2016. This means - amongst other things- that it is illegal to sell this plant in the whole of the European Union or to dump it in the environment.

Hydrilla Verticillata
''Hydrilla'' (waterthyme) is a genus of aquatic plant, usually treated as containing just one species, ''Hydrilla verticillata'', though some botanists divide it into several species. It is native to the cool and warm waters of the Old World in Asia, Africa and Australia, with a sparse, scattered distribution; in Australia from Northern Territory, Queensland, and New South Wales.Flora Europaea''Hydrilla''/ref>Flora of Taiwan''Hydrilla''Australian Plant Name Index''Hydrilla''/ref> The stems grow up to 1–2m long. The leaves are arranged in whorls of two to eight around the stem, each leaf 5–20 mm long and 0.7–2 mm broad, with serrations or small spines along the leaf margins; the leaf midrib is often reddish when fresh. It is monoecious (sometimes dioecious), with male and female flowers produced separately on a single plant; the flowers are small, with three sepals and three petals, the petals 3–5 mm long, transparent with red streaks. It reproduces prim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neophyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zostera
''Zostera'' is a small genus of widely distributed seagrasses, commonly called marine eelgrass, or simply seagrass or eelgrass, and also known as seaweed by some fishermen and recreational boaters including yachtsmen. The genus ''Zostera'' contains 15 species. Ecology ''Zostera marina'' is found on sandy substrates or in estuaries, usually submerged or partially floating. Most ''Zostera'' are perennial. They have long, bright green, ribbon-like leaves, the width of which are about . Short stems grow up from extensive, white branching rhizomes. The flowers are enclosed in the sheaths of the leaf bases; the fruits are bladdery and can float. ''Zostera'' beds are important for sediment deposition, substrate stabilization, as substrate for epiphytic algae and micro-invertebrates, and as nursery grounds for many species of economically important fish and shellfish. ''Zostera'' often forms beds in bay mud in the estuarine setting. It is an important food for brant geese and wigeon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potamogeton Crispus
''Potamogeton crispus'', the crisp-leaved pondweed, curly pondweed, curly-leaf pondweed or curled pondweed, is a species of aquatic plant (hydrophyte) native to Eurasia but an introduced species and often a noxious weed in North America. Description Curly-leaf pondweed is a rhizome, rhizomatous perennial herb producing a flattened, branching stem up to a meter long. The submerged leaves are alternately arranged. The leaves are sessile, linear or oblong in shape, long and wide. The leaves may be bright green, olive green or (especially later in the season) fibrous and brownish and have noticeably serrated margins, a feature that distinguishes them from other pondweeds. The leaves usually have wavy edges but this is not always apparent, especially on new growth. Turion (botany), Turions occur in leaf axils and at stem tips. The inflorescence is a short spike of flowers emerging above the water surface. It flowers from May until October. The turions of the plant develop along w ...

Gill
A gill () is a respiratory organ that many aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. The microscopic structure of a gill presents a large surface area to the external environment. Branchia (pl. branchiae) is the zoologists' name for gills (from Ancient Greek ). With the exception of some aquatic insects, the filaments and lamellae (folds) contain blood or coelomic fluid, from which gases are exchanged through the thin walls. The blood carries oxygen to other parts of the body. Carbon dioxide passes from the blood through the thin gill tissue into the water. Gills or gill-like organs, located in different parts of the body, are found in various groups of aquatic animals, including mollusks, crustaceans, insects, fish, and amphibians. Semiterrestrial marine animals such as crabs and mudskippers have gill cham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the other wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically extent, is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is distance between the length from one end of an individual's arms (measured at the fingertips) to the other when raised parallel to the ground at shoulder height at a 90º angle. Former professional basketball player Manute Bol stood at and owned one of the largest wingspans at . Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, independently of wing shape or sweep. Implications for aircraft design and anima ...
