Hairy-nosed Otter
The hairy-nosed otter (''Lutra sumatrana'') is a semiaquatic mammal endemic to Southeast Asia and one of the rarest and least known otter species. It is threatened by loss of natural resources and poaching. Description The hairy-nosed otter has a short brown fur that becomes paler on the belly. Its rhinarium is covered with short hair. Its upper lip and chin are whitish. Some individuals are reddish-chestnut in colour. Its body is long, its tail slender, and its fully webbed paws have prominent claws. Head-to-body length ranges from , tail length from , and weight from . Its skull is flatter than that of smooth-coated otter, and it has smaller teeth. Its forepaws are wide and smaller than the hind paws with about . The hairy-nosed otter is the least known of the Asian otters, and is also the most difficult to identify in the field. In most other respects, it is similar to the European otter (''Lutra lutra''). Distribution and habitat This hairy-nosed otter occurs in Southeas ...

John Edward Gray
John Edward Gray, FRS (12 February 1800 – 7 March 1875) was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frederick Gray (1766–1828). The same is used for a zoological name. Gray was keeper of zoology at the British Museum in London from 1840 until Christmas 1874, before the natural history holdings were split off to the Natural History Museum. He published several catalogues of the museum collections that included comprehensive discussions of animal groups and descriptions of new species. He improved the zoological collections to make them amongst the best in the world. Biography Gray was born in Walsall, but his family soon moved to London, where Gray studied medicine. He assisted his father in writing ''The Natural Arrangement of British Plants'' (1821). After being blackballed by the Linnean Society of London, Gray shifted his interest from botany to zoology. He began his zoolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Camera Trap
A camera trap is a camera that is automatically triggered by a change in some activity in its vicinity, like presence of an animal or a human being. It is typically equipped with a motion sensor – usually a passive infrared (PIR) sensor or an active infrared (AIR) sensor using an infrared light beam. Camera trapping is a method for capturing wild animals on film when researchers are not present, and has been used in ecological research for decades. In addition to applications in hunting and wildlife viewing, research applications include studies of nest ecology, detection of rare species, estimation of population size and species richness, and research on habitat use and occupation of human-built structures. Camera traps, also known as trail cameras, are used to capture images of wildlife with as little human interference as possible. Since the introduction of commercial infrared-triggered cameras in the early 1990s, their use has increased. With advancements in the qu ...

Ipomoea Aquatica
''Ipomoea aquatica'', widely known as water spinach, is a semi- aquatic, tropical plant grown as a vegetable for its tender shoots. ''I. aquatica'' is generally believed to have been first domesticated in Southeast Asia. It is widely cultivated in Southeast Asia, East Asia, and South Asia. It grows abundantly near waterways and requires little to no care. Description ''Ipomoea aquatica'' grows in water or on moist soil. Its stems are or longer, rooting at the nodes, and they are hollow and can float. The leaves vary from typically sagittate (arrow head-shaped) to lanceolate, long and broad.

Salvinia Cucullata
''Salvinia'', a genus in the family Salviniaceae, is a floating fern named in honor of Anton Maria Salvini, a 17th-century Italian scientist. Watermoss is a common name for ''Salvinia''. The genus was published in 1754 by Jean-François Séguier, in his description of the plants found round Verona, ''Plantae Veronenses'' Twelve species are recognized, at least three of which (''S. molesta'', ''S. herzogii'', and ''S. minima'') are believed to be hybrids, in part because their sporangia are found to be empty. ''Salvinia'' is related to the other water ferns, including the mosquito fern ''Azolla''. Recent sources include both ''Azolla'' and ''Salvinia'' in Salviniaceae, although each genus was formerly given its own family. ''Salvinia'', like the other ferns in order Salviniales, are heterosporous, producing spores of differing sizes. However, leaf development in ''Salvinia'' is unique. The upper side of the floating leaf, which appears to face the stem axis, is morphologically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pistia Stratiotes
''Pistia'' is a genus of aquatic plants in the arum family, Araceae. It is the sole genus in the tribe ''Pistieae'' which reflects its systematic isolation within the family. The single species it comprises, ''Pistia stratiotes'', is often called water cabbage, water lettuce, Nile cabbage, or shellflower. Its native distribution is uncertain but is probably pantropical; it was first discovered from the Nile near Lake Victoria in Africa. It is now present, either naturally or through human introduction, in nearly all tropical and subtropical fresh waterways and is considered an invasive species as well as a mosquito breeding habitat. The genus name is derived from the Greek word πιστός (''pistos''), meaning "water," and refers to the aquatic nature of the plants. The specific epithet is also derived from a Greek word, στρατιώτης, meaning "soldier," which references the sword-shaped leaves of some plants in the '' Stratiotes'' genus.

Eleocharis Dulcis
''Eleocharis dulcis'', the Chinese water chestnut or water chestnut, is a grass-like sedge native to Asia, tropical Africa, and Oceania. It is grown in many countries for its edible corms. The water chestnut is not a nut, but an aquatic vegetable that grows in marshes, under water, in the mud. It has stem-like, tubular green leaves that grow to about . The water caltrop, which also is referred to by the same name, is unrelated and often confused with the water chestnut. The small, rounded corms have a crisp, white flesh and may be eaten raw, slightly boiled, or grilled, and often are pickled or tinned. They are a popular ingredient in Chinese dishes. In China, they are most often eaten raw, sometimes sweetened. They also may be ground into a flour form used for making water chestnut cake, which is common as part of '' dim sum'' cuisine. They are unusual among vegetables for remaining crisp even after being cooked or canned, because their cell walls are cross-linked a ...
