Echyridella onekaka is a species of freshwater mussel endemic to New Zealand. E. onekaka is an aquatic bivalve mollusc in the family Unionidae, the river mussels.
The species was first recognised as a distinct species by Mark Fenwick and Bruce Marshall in 2006. It can be distinguished from Echyridella menziesii by a more strongly separated anterior pedal retractor muscle. [2]
Echyridella onekaka is found exclusively in the north-west of the South Island. [3] It is the rarest known freshwater mussel species in New Zealand. [4]
Crayfish are freshwater crustaceans belonging to the clade Astacidea, which also contains lobsters. In some locations, they are also known as baybugs, crabfish, craws, crawfish, crawdaddies, crawdads, freshwater lobsters, mountain lobsters, mudbugs, rock lobsters, signal crawfish, or yabbies. Taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills. Some species are found in brooks and streams, where fresh water is running, while others thrive in swamps, ditches, and paddy fields. Most crayfish cannot tolerate polluted water, although some species, such as Procambarus clarkii, are hardier. Crayfish feed on animals and plants, either living or decomposing, and detritus.
Mussel is the common name used for members of several families of bivalve molluscs, from saltwater and freshwater habitats. These groups have in common a shell whose outline is elongated and asymmetrical compared with other edible clams, which are often more or less rounded or oval.
The zebra mussel is a small freshwater mussel. The species originates from the lakes of southern Russia and Ukraine, but has been accidentally introduced to numerous other areas and has become an invasive species in many countries worldwide. Since the 1980s, the species has invaded the Great Lakes, Hudson River, and Lake Travis.
Fathom Five National Marine Park is a National Marine Conservation Area in the Georgian Bay part of Lake Huron, Ontario, Canada, that seeks to protect and display shipwrecks and lighthouses, and conserve freshwater ecosystems. Parks Canada has management plans for the aquatic and terrestrial ecosystems, with a multi-action plan for species that are at risk, including endemic species, the Monarch butterfly, the eastern ribbonsnake, and the eastern whip-poor-will. The aquatic ecosystems in the park are also of particular interest. Many fish, shellfish, amphibians, and eels are an attraction for naturalists in the park. Much of this wildlife is accessible to scuba divers and snorkellers in the park. The many shipwrecks make the park a popular scuba diving destination, and glass bottom boat tours leave Tobermory regularly, allowing tourists to see the shipwrecks without having to get wet. Additionally, there are three main popular hiking trails found within Fathom Five National Marine Park that provides visitors with views of old growth forests and the Georgian Bay. The Saugeen Ojibway Peoples have inhabited the Bruce Peninsula and the area that is now Fathom Five National Marine Park for thousands of years. This land provided for their communities and their people with the plethora of wildlife and plant life. They provide the local knowledge about Lake Huron and its ecological value to the reserve, park, and their overall livelihood. Parks Canada and Saugeen Ojibway People's collaboration is said to yield a benefit to both parties with regard to overall ecosystem knowledge.
Pelorus Sound is the largest of the sounds which make up the Marlborough Sounds at the north of the South Island, New Zealand.
A number of introduced species, some of which have become invasive species, have been added to New Zealand's native flora and fauna. Both deliberate and accidental introductions have been made from the time of the first human settlement, with several waves of Polynesian people at some time before the year 1300, followed by Europeans after 1769.

The New Zealand grayling is an extinct species of fish that was endemic to New Zealand. It was known to the Māori by many names, including pokororo, paneroro, kanae-kura, and most commonly, upokororo. The variety of names for the fish came from either multiple tribes, or to describe the fish at different periods of its life cycle. Even though this fish is named grayling, it is not related to European or American graylings and lacks the large dorsal fin ‘typical’ graylings are characterised by. It is, however, closely related to the Australian grayling. The New Zealand grayling was an amphidromous species, migrating between freshwater and saltwater during different seasons as well as stages in their life cycle. The last sighting of the New Zealand grayling was in 1923, and it was declared extinct in 2018.
