A snail is, in loose terms, a shelled gastropod. The name is most often applied to land snails, terrestrial pulmonate gastropod molluscs. However, the common name snail is also used for most of the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract completely into. When the word "snail" is used in this most general sense, it includes not just land snails but also numerous species of sea snails and freshwater snails. Gastropods that naturally lack a shell, or have only an internal shell, are mostly called slugs, and land snails that have only a very small shell are often called semi-slugs.
The gastropods, commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda.
Hahajima is the second-largest island of the Ogasawara Islands south of the Japanese main island chain. It is about 21 km2 (8 sq mi) in area with a population of 440.
Sea snail is a common name for slow moving marine gastropod molluscs usually with visible external shells, such as whelk or abalone. They share the taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible shell.

Lamprocystis is a genus of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the subfamily Microcystinae in the family Euconulidae, the hive snails.
Lamprocystis hahajimana is a species of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Euconulidae, the hive snails.
Lamprocystis hornbosteli is a species of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Euconulidae, the hive snails.
Lamprocystis misella is a species of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Euconulidae, the hive snails.
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. 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.
Euconulidae is a taxonomic family of minute, air-breathing land snails, terrestrial pulmonate gastropod mollusks or micromollusks in the superfamily Trochomorphoidea.
Eucalyptus fastigata, commonly known as brown barrel or cut-tail, is a species of medium-sized to tall tree that is endemic to southeastern Australia. It has fibrous or stringy bark on the trunk and larger branches, smooth bark above, lance-shaped to curved adult leaves, flower buds in groups of eleven or more, white flowers and conical or pair-shaped fruit.
Freshwater snails are gastropod mollusks which live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a shell, with very few exceptions. Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung. Most feed on algae, but many are detritivores and some are filter feeders.
Grevillea laurifolia, commonly known as the laurel-leaf grevillea, is a spreading prostrate shrub native to eastern Australia.
Miralda is a genus of sea snails, marine gastropod mollusks in the family Pyramidellidae, the pyrams, and their allies.
Turbonilla fastigata is a species of sea snail, a marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies.
Anticlimax is a genus of sea snails, marine gastropod mollusks in the family Tornidae within the superfamily Truncatelloidea.
Acropora multiacuta is a species of acroporid coral that was first described by F. Nemenzo in 1967. Found in marine, tropical shallow reefs in lagoons, on rocks or on the tops of reefs, it occurs at depths between 3 and 15 m. It is classed as a vulnerable species on the IUCN Red List, and it has a decreasing population. It is uncommon but found over a large area, including in two regions of Indonesia and the Great Barrier Reef, and is classified under CITES Appendix II.
Opadometa is a genus of long-jawed orb-weavers that was first described by Allan Frost Archer in 1951. Their morphology and behavior indicate that these spiders are likely related to Leucauge.
Opadometa fastigata, the pear-shaped leucauge, is a species of spiders in the family Tetragnathidae. It is found in India to Philippines and Sulawesi.
