Lake Alexander (Northern Territory)
Lake Alexander is a man-made lake named in honour of Alec Fong Lim who was Lord Mayor of Darwin from 1984 to 1990. The lake is located in Fannie Bay Darwin, Northern Territory, Australia and was officially opened on the 21 July 1991 for recreational use by the people of Darwin. The water in the lake is refreshed with pumps bringing water from the adjoining harbour through filters intended to prevent marine organisms from entering. This system has succeeded in keeping large predators such as saltwater crocodiles and bull sharks, and the deadly box jellyfish. However the lake has been closed to swimming twice, once due to a large Orange-spotted grouper and once due to an outbreak of a stinging species of Cassiopea jelly fish.

Darwin, Northern Territory
Darwin ( ; Larrakia: ) is the capital city of the Northern Territory, Australia. With an estimated population of 147,255 as of 2019, the city contains the majority of the residents of the sparsely populated Northern Territory. It is the smallest, wettest, and most northerly of the Australian capital cities and serves as the Top End's regional centre. Darwin's proximity to Southeast Asia makes the city's location a key link between Australia and countries such as Indonesia and East Timor. The Stuart Highway begins in Darwin, extends southerly across central Australia through Tennant Creek and Alice Springs, concluding in Port Augusta, South Australia. The city is built upon a low bluff overlooking Darwin Harbour. Darwin's suburbs begin at Lee Point in the north and stretch to Berrimah in the east. The Stuart Highway extends to Darwin's eastern satellite city of Palmerston and its suburbs. The Darwin region, like much of the Top End, experiences a tropical climate with a wet a ...

Reservoir
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam A dam is a barrier that stops or restricts the flow of surface water or underground streams ...

Lake
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saltwater Crocodile
The saltwater crocodile (''Crocodylus porosus'') is a crocodilian native to saltwater habitats and brackish wetlands from India's east coast across Southeast Asia and the Sundaic region to northern Australia and Micronesia. It has been listed as Least Concern on the IUCN Red List since 1996. It was hunted for its skin throughout its range up to the 1970s, and is threatened by illegal killing and habitat loss. It is regarded as dangerous to humans. The saltwater crocodile is considered to be the largest living reptile. Males can grow up to a length of , rarely exceeding , and a weight of . Females are much smaller and rarely surpass . It is also called the estuarine crocodile, Indo-Pacific crocodile, marine crocodile, sea crocodile, and informally as the saltie. A large and opportunistic hypercarnivorous apex predator, they ambush most of their prey and then drown or swallow it whole. They are capable of prevailing over almost any animal that enters their territory, including ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bull Shark
The bull shark (''Carcharhinus leucas''), also known as the Zambezi shark (informally zambi) in Africa and Lake Nicaragua shark in Nicaragua, is a species of requiem shark commonly found worldwide in warm, shallow waters along coasts and in rivers. It is known for its aggressive nature, and presence mainly in warm, shallow brackish and freshwater systems including estuaries and lower reaches of rivers. Bull sharks are euryhaline and can thrive in both salt and fresh water. They are known to travel far up rivers, and have been known to travel up the Mississippi River as far as Alton, Illinois, about from the ocean, but few freshwater interactions with humans have been recorded. Larger-sized bull sharks are probably responsible for the majority of nearshore shark attacks, including many incidents of shark bites attributed to other species. Unlike the river sharks of the genus '' Glyphis'', bull sharks are not true freshwater sharks, despite their ability to survive in freshwa ...

Box Jellyfish
Box jellyfish (class Cubozoa) are cnidarian invertebrates distinguished by their box-like (i.e. cube-shaped) body. Some species of box jellyfish produce potent venom delivered by contact with their tentacles. Stings from some species, including ''Chironex fleckeri'', ''Carukia barnesi'', ''Malo kingi'', and a few others, are extremely painful and often fatal to humans. Taxonomy and systematics At least 51 species of box jellyfish were known as of 2018. These are grouped into two orders and eight families. A few new species have since been described, and it is likely that additional undescribed species remain. Cubozoa represents the smallest cnidarian class with approximately 50 species. Class Cubozoa * Order Carybdeida ** Family Alatinidae ** Family Carukiidae ** Family Carybdeidae ** Family Tamoyidae ** Family Tripedaliidae * Order Chirodropida ** Family Chirodropidae ** Family Chiropsalmidae ** Family Chiropsellidae Description The medusa form of a box jellyfish has a s ...

Orange-spotted Grouper
The orange-spotted grouper (''Epinephelus coioides''), also known as the brown-spotted rockcod, estuary cod, estuary rockcod, goldspotted rockcod, greasy cod, North-west groper, orange spotted cod or blue-and-yellow grouper, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It has an Indo-Pacific distribution and is found in marine and brackish waters. Description The orange-spotted grouper has an elongate body which has a standard length that is 2.9 to 3.7 times its depth. The dorsal profile of the head is flat or slightly convex between the eyes, the preopercle has enlarged serrations at its angle and a shallow notch just above the angle. The upper margin of the gill cover may be straight or slightly convex. The dorsal fin contains 11 spines and 13-16 soft rays while the anal fin has 3 spines and 8 soft rays. The membranes between the dorsal fin spines are obv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cassiopea
''Cassiopea'' (upside-down jellyfish) is a genus of true jellyfish and the only members of the family Cassiopeidae. They are found in warmer coastal regions around the world, including shallow mangrove swamps, mudflats, canals, and turtle grass flats in Florida, and the Caribbean and Micronesia. The medusa usually lives upside-down on the bottom, which has earned them the common name. These jellyfish partake in a symbiotic relationship with photosynthetic dinoflagellates and therefore, must lie upside-down in areas with sufficient light penetration to fuel their energy source. Where found, there may be numerous individuals with varying shades of white, blue, green and brown. Species According to the ''World Register of Marine Species'', this genus includes 8 species: * ''Cassiopea andromeda'' (Forsskål, 1775) * '' Cassiopea depressa'' Haeckel, 1880 * '' Cassiopea frondosa'' (Pallas, 1774) * ''Cassiopea maremetens'' Gershwin, Zeidler & Davie, 2010 * '' Cassiopea medusa'' ...
