Placostylus Ambagiosus
''Placostylus ambagiosus'' is a species of flax snail (Māori: pūpū whakarongotaua), a large air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Bothriembryontidae. Description This snail has a large ( long) shell, which is heavily calcified. The size of the adult shell is habitat dependent, but the shell shape is not plastic. ''Placostylus ambagiosus'' is highly valued by Te Aupōuri me Ngāti Kurī (the indigenous people of northern New Zealand) as a food source, musical instrument and in the past this snail provided alarm calls at night warning of approaching invaders. Distribution This land snail species occurs in New Zealand. It is restricted to a small fragmented area of Northland Region, including the Aupouri Peninsula and Motuopao Island. In the past local Māori moved and propagated populations of ''Placostylus ambagiosus,'' so today at least three extant populations are found on old pā sites (fortified settlements), along wit ...

Bothriembryontidae
Bothriembryontidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Orthalicoidea. Taxonomy This family has been named Placostylidae and had no subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). Breure et al. (2010) moved '' Prestonella'' and '' Bothriembryon'' to Placostylidae. Breure & Romero (2012) confirmed previous results from 2010 and they renamed Placostylidae to Bothriembryontidae. * subfamily Bothriembryontinae Iredale, 1937 * subfamily Placostylinae Pilsbry, 1946 - for species from New Zealand and Melanesia Prestonellinae was formally described as a new subfamily within Bothriembryontidae in 2016.

Land Snail
A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. ''Land snail'' is the common name for terrestrial gastropod mollusks that have shells (those without shells are known as slugs). However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and fresh water, and others are relatively amphibious between land and salt water. Land snails are a polyphyletic group comprising at least ten independent evolutionary transitions to terrestrial life (the last common ancestor of all gastropods was marine). The majority of land snails are pulmonates that have a lung and breathe air. Most of the non-pulmonate land snails belong to lineages in the Caenogastropoda, and tend to have a gill and an operculum. The largest clade of land snails is the Cyclophoroidea, with more than 7,000 species. Many of these operculate land snails live in habitats or microhabitats ...

Northland Region
The Northland Region ( mi, Te Tai Tokerau) is the northernmost of New Zealand's 16 local government regions. New Zealanders sometimes refer to it as the Winterless North because of its mild climate all throughout the year. The main population centre is the city of Whangārei, and the largest town is Kerikeri. At the 2018 New Zealand census, Northland recorded a population growth spurt of 18.1% since the previous 2013 census, placing it as the fastest growing region in New Zealand, ahead of other strong growth regions such as the Bay of Plenty (2nd with 15%) and Waikato (3rd with 13.5%). Geography The Northland Region occupies the northern 80% (265 km) of the 330 km Northland Peninsula, the southernmost part of which is in the Auckland Region. Stretching from a line at which the peninsula narrows to a width of just 15 km a little north of the town of Wellsford, Northland Region extends north to the tip of the Northland Peninsula, covering an area of 13,940&nb ...

Lord Howe Island
Lord Howe Island (; formerly Lord Howe's Island) is an irregularly crescent-shaped volcanic remnant in the Tasman Sea between Australia and New Zealand, part of the Australian state of New South Wales. It lies directly east of mainland Port Macquarie, northeast of Sydney, and about southwest of Norfolk Island. It is about long and between wide with an area of , though just of that comprise the low-lying developed part of the island. Along the west coast is a sandy semi-enclosed sheltered coral reef lagoon. Most of the population lives in the north, while the south is dominated by forested hills rising to the highest point on the island, Mount Gower (). The Lord Howe Island Group comprises 28 islands, islets, and rocks. Apart from Lord Howe Island itself, the most notable of these is the volcanic and uninhabited Ball's Pyramid about to the southeast of Howe. To the north lies a cluster of seven small uninhabited islands called the Admiralty Group. The first repo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Bothriembryon'' is a genus of tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Bothriembryontidae. B. J. Smith (1992) made the last review of the genus summarizing all known data. Distribution The land snail genus ''Bothriembryon'' is endemic to Australia but forms part of the Gondwanan element in the superfamily Orthalicoidea. ''Bothriembryon'' species are mostly patchy in their distribution. Taxonomy This genus was classified with the Bulimulidae by Pilsbry (1900), Breure (1979)Breure A.S. H.

Molluscan Research
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.
