Whangapoua Harbour
Whangapoua Harbour is a shallow natural harbour in the northeast of the Coromandel Peninsula. It is located between Whangapoua in the north, Te Rerenga in the southwest, and Matarangi on the Omara Spit in the north separating it from the ocean. Two boat ramps and a jetty provide boat access into the harbour. Geography Waitekuri River, Opitonui River, Owera Stream, Otanguru Stream, and Mapauriki Stream all drain the surrounding hills that are part of the Coromandel Range into the 12 km2 harbour, which only has a single narrow mouth to the sea. Tidal flows have built up a bar at the 600m wide entrance, which makes navigation difficult in large swells. The entrance is flanked by the rocky Te Rehutae Point, rising to 85m to the west, and Omara Spit to the east. The southern and eastern estuary arms contain extensive areas of grey mangroves. The surrounding land is partly farm land, pine plantations, and native bush. Recreation The harbour is popular for fishing, particularly wit ...

Harbour
A harbor (American English), harbour (British English; see spelling differences), or haven is a sheltered body of water where ships, boats, and barges can be docked. The term ''harbor'' is often used interchangeably with ''port'', which is a man-made facility built for loading and unloading vessels and dropping off and picking up passengers. Ports usually include one or more harbors. Alexandria Port in Egypt is an example of a port with two harbors. Harbors may be natural or artificial. An artificial harbor can have deliberately constructed breakwaters, sea walls, or jettys or they can be constructed by dredging, which requires maintenance by further periodic dredging. An example of an artificial harbor is Long Beach Harbor, California, United States, which was an array of salt marshes and tidal flats too shallow for modern merchant ships before it was first dredged in the early 20th century. In contrast, a natural harbor is surrounded on several sides of land. Examples ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mangrove
A mangrove is a shrub or tree that grows in coastal saline water, saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse, as a result of convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs, and became widely distributed in part due to the plate tectonics, movement of tectonic plates. The oldest known fossils of Nypa fruticans, mangrove palm date to 75 million years ago. Mangroves are salt-tolerant trees, also called halophytes, and are adapted to live in harsh coastal conditions. They contain a complex salt filtration system and a complex root system to cope with saltwater immersion and wave action. They are ad ...

Patiriella Regularis
__NOTOC__ ''Patiriella regularis'', or New Zealand common cushion star, is a sea star of the family Asterinidae, native to New Zealand. It has an arm spread of up to . It is one of New Zealand's most common rocky shore starfish. It is abundant in shallow water around both mainland islands. They come in a large range of colours and have 4–6 arms. They feed on algae, barnacles and invertebrates. To catch their food the cushion star inflates its cushion and then deflates on top of its prey. They were introduced into waters in south east Tasmania, where they have become well established. Concern exists that they may be an invasive species. They breed in January to March. Once fertilised, 9–10 weeks are needed for them to grow from larvae. Research A genetic variance is found in ''P. regularis'' from the North and South of New Zealand. Geographic barriers, and coastal upwelling Upwelling is an oceanographic phenomenon that involves wind-driven motion of dense, cooler, and ...

Pacific Oyster
The Pacific oyster, Japanese oyster, or Miyagi oyster (''Magallana gigas''), is an oyster native to the Pacific coast of Asia. It has become an introduced species in North America, Australia, Europe, and New Zealand. Etymology The genus ''Magallana'' is named for the Portuguese explorer Ferdinand Magellan and its specific epithet ''gígās'' is from the Greek for "giant". It was previously placed in the genus '' Crassostrea''; from the Latin ''crass'' meaning "thick", ''ostrea'' meaning "oyster", and ''Crassostrea gigas'' is considered by part of the scientific community to be the proper denomination as an accepted alternative in WoRMS, Description The shell of ''M. gigas'' varies widely with the environment where it is attached. Its large, rounded, radial folds are often extremely rough and sharp. The two valves of the shell are slightly different in size and shape, the right valve being moderately concave. Shell colour is variable, usually pale white or off-white. Mature spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lunella Smaragda
''Lunella smaragda'', common name the cat's eye snail, is a species of sea snail, a marine gastropod mollusk in the family Turbinidae, the turban snails.

Amphibola Crenata
''Amphibola crenata'' (''tītiko'' in the Māori language or mud-flat snail in English) is a species of air-breathing snail with an operculum, a pulmonate gastropod mollusc which lives in a habitat that is intermediate between the land and the sea, not entirely terrestrial and not entirely marine.Rosenberg, G. (2011). Amphibola crenata (Gmelin, 1791).

Austrovenus Stutchburyi
''Austrovenus stutchburyi'', common name the New Zealand cockle or New Zealand little neck clam, is an edible saltwater clam, a marine bivalve mollusc in the family Veneridae, the Venus clams. Its Māori name is (North Island) or (South Island). Habitat Cockles live in harbours and estuaries in New Zealand. They live in the subtidal to intertidal zone, and when they are in the intertidal zone they live between the low tide mark and the mid tide mark. Cockles are unable to survive above the mid tide mark because of the increased exposure time. Cockles prefer to live in soft mud and fine sand, however they can be suffocated by extremely fine sand. For this reason, they mainly live in areas with a large grain size. The cockles bury 2 to 3 cm under the sand. Body Cockles have a soft body which is protected from predation, desiccation and wave movement by a sturdy shell. Predators find it difficult to pierce the shell of adult cockles. Sea birds drop cockles from high up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hormosira Banksii
''Hormosira banksii'', also known as Neptune's necklace, Neptune's pearls, sea grapes, or bubbleweed) is a species of seaweed (brown algae, Fucales) native to Australia and New Zealand. The genus ''Hormosira'' is monotypic. Distribution ''Hormosira'' is native to southeastern Australia (including Tasmania, Lord Howe Island and Norfolk Island) and New Zealand. Despite substantial morphological variation across its range, the species represents a single species and the genus ''Hormosira'' is monotypic. Genetic analyses of mitochondrial COI and microsatellite DNA sequence data have indicated that there is low genetic variation across the range of the species in Australia. Description ''Hormosira'' is a perennial species of seaweed (brown algae, Fucales). It is abundant on low-energy rocky reefs within the intertidal zone, where it outcompetes other algal species due to its high tolerance to desiccation. Plants vary significantly in morphology.

Zostera Muelleri
''Zostera muelleri '' is a southern hemisphere temperate species of seagrass native to the seacoasts of South Australia, Victoria and Tasmania.Paul Friedrich August Ascherson. 1867. Sitzungsberichte der Gesellschaft Naturforschender Freunde zu Berlin : 15. ''Zostera muelleri '' and New Zealand. Today, ''Zostera muelleri'' can be found in regions of Australia, New Zealand, and Papua New Guinea, as well as areas of the eastern Indian Ocean, and the southwest and western central Pacific Ocean. ''Zostera muelleri'' is a marine angiosperm, and is commonly referred to as eelgrass or garweed. It is a fast growing and readily colonizing species that serves as a feeding ground for wading birds and aquatic animals, and a breeding ground for juvenile fish and shrimp species. Seagrasses are a flowering plant species, not to be confused with seaweed, which do not form flowers, fruits, and seeds to reproduce. Seagrasses are important to the marine ecosystem for many reasons. For one, they p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
