Achatinella bulimoides is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Achatinellidae. This species is endemic to Hawaii.
The dextral or sinistral shell is ovate-oblong and subventricose. The shell has 6+1⁄4 whorls. The shell is similar in form to Achatinella livida , but the spire is less thickened and more pointed at the apex. The color is whitish with chestnut bands, and the apex is pale brown. The ground-color, in some specimens, is pale chestnut or ferruginous, banded with darker shades. Other specimens are pure white. The aperture is white. The suture is scarcely if at all margined by a groove. [3]
The height of the shell is 21.3 millimetres (0.84 in). The width of the shell is 11.8 millimetres (0.46 in). [3]
Achatinella rosea Swainson, 1828 is a variety of Achatinella bulimoides. [3] Its sinistral shell is a pale, rose color, with two obsolete white bands. The shell has 6+1⁄3 whorls. The margin of the lip and columella are of a deeper rose-color, and the aperture white. It should be observed that the subsutural groove is very distinct. The height of the shell is 22.3 millimetres (0.88 in). The width of the shell is 13.5 millimetres (0.53 in). [3]
Achatinella is a tropical genus of colorful land snails in the monotypic Achatinellidae subfamily Achatinellinae. Species are arboreal pulmonate gastropod mollusks with some species called Oʻahu tree snails or kāhuli in the Hawaiian language.
The gastropod shell is part of the body of a gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group.

Seashore wildlife habitats exist from the Tropics to the Arctic and Antarctic. Seashores and beaches provide varied habitats in different parts of the world, and even within the same beach. Phytoplankton is at the bottom of some food chains, while zooplankton and other organisms eat phytoplankton. Kelp is also autotrophic and at the bottom of many food chains. Coastal areas are stressed through rapid changes, for example due to tides.
