Sinistral and dextral, in some scientific fields, are the two types of chirality ("handedness") or relative direction. The terms are derived from the Latin words for "left" (sinister) and "right" (dexter). Other disciplines use different terms or simply use left and right.
Kapas Island is an island in Marang District, Terengganu, Malaysia, with a smaller island, Pulau Gemia, located north of it. It measures roughly 1.5 by 2.5 km. Its name, Pulau Kapas, refers to the island's white beaches. The island has tropical jungle, clear seawater, white sand beaches and coral reefs in the surrounding waters. It is promoted as a "diving and snorkeling paradise". The island is reached by ferry from Marang. Kapas is the location where most of the research on the enigmatic Amphidromus snails is carried out.
Amphidromus cognatus is a large camaenid land snail endemic to Australia.
Amphidromus is a genus of tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Camaenidae. The shells of Amphidromus are relatively large, from 25 mm (0.98 in) to 75 mm (3.0 in) in maximum dimension, and particularly colorful. During the 18th century, they were among the first Indonesian land snail shells brought to Europe by travelers and explorers. Since then, the genus has been extensively studied: several comprehensive monographs and catalogs were authored by naturalists and zoologists during the time period from the early 19th to the mid 20th centuries. Modern studies have focused on better understanding the evolutionary relationships within the group, as well as solving taxonomic problems.
