Placiphorella, the veiled chiton, is a genus of polyplacophoran molluscs with precephalic tentacles, [1] which are used in feeding. [2]
Caudofoveata is a small class within the phylum Mollusca, also known as Chaetodermomorpha. The class is often combined with Solenogastres and termed Aplacophora, but some studies have cast doubt on the monophyly of this group.
Chitons are marine molluscs of varying size in the class Polyplacophora, formerly known as Amphineura. About 940 extant and 430 fossil species are recognized.
A chiton is a form of tunic that fastens at the shoulder, worn by men and women of ancient Greece and Rome. There are two forms of chiton: the Doric and the later Ionic. According to Herodotus, popular legend was that Athenian women began to wear the chiton as opposed to the peplos after several women stabbed a messenger to death with the bronze pins characteristic of the peplos.
A himation was a type of clothing, a mantle or wrap worn by ancient Greek men and women from the Archaic through the Hellenistic periods. It was usually worn over a chiton and/or peplos, but was made of heavier drape and played the role of a cloak or shawl. When the himation was used alone, without a chiton, it served both as a chiton and as a cloak. The himation was markedly less voluminous than the Roman toga. Many vase paintings depict women wearing a himation as a veil covering their faces.
The gumboot chiton, also known as the giant western fiery chiton or giant Pacific chiton, is the largest of the chitons, growing to 36 cm (14 in) and capable of reaching a weight of more than 2 kg (4.4 lb). It is found along the shores of the northern Pacific Ocean from Central California to Alaska, across the Aleutian Islands to the Kamchatka Peninsula and south to Japan. It inhabits the lower intertidal and subtidal zones of rocky coastlines. The gumboot chiton's appearance has led some tidepoolers to refer to it, fondly, as the "wandering meatloaf". The name "gumboot chiton" seems to derive from a resemblance to part of a rubber Wellington boot or "gum rubber" boot.
Chiton is a genus of chitons, a polyplacophoran mollusk in the family Chitonidae.
Chiton glaucus, common name the green chiton or the blue green chiton, is a species of chiton, a marine polyplacophoran mollusk in the family Chitonidae, the typical chitons. It is the most common chiton species in New Zealand. Chiton glaucus is part of a very primitive group of mollusc with evidence of being present in up to 80 million years of the fossil record.
A valve is each articulating part of the shell of a mollusc or another multi-shelled animal such as brachiopods and some crustaceans. Each part is known as a valve or in the case of chitons, a "plate". Members of two classes of molluscs, the Bivalvia (clams) and the Polyplacophora (chitons), have valves.
Mopalia spectabilis, commonly known as the red-flecked mopalia, is a species of chiton.
Chiton magnificus, the liquorice sea cradle, is a Southeast Pacific species of edible chiton, a marine polyplacophoran mollusk in the family Chitonidae, the typical chitons.
Acanthopleura granulata, common name the West Indian fuzzy chiton, is a medium-sized tropical species of chiton. This type of chiton's activity does not depend on spring-neap oscillations leading to lower locomotion loss. Its morphology is different from usual chitons as it has a fifth valve, which is split into halves.
Acanthochitonidae is a family of marine mollusks belonging to the class Polyplacophora, commonly known as chitons. Species are widely distributed throughout the world's oceans, but are most commonly found in the shallow waters of the Pacific Ocean, from Alaska to Chile.
Acanthochitona fascicularis is a common chiton in the family Acanthochitonidae.
Mopaliidae is a family of marine molluscs in the class Polyplacophora.
Plaxiphora albida, the white Plaxiphora chiton, is a species of chiton in the family Mopaliidae.
Enoplochiton echinatus is a Southeast Pacific species of edible chiton, a marine polyplacophoran mollusc in the family Chitonidae, the typical chitons.
Acanthochitona crinita is a species of marine chiton in the family Acanthochitonidae. It is found on rocky coasts in the northeastern Atlantic Ocean, the North Sea and the Mediterranean Sea.
Tonicella marmorea is a species of chiton, a polyplacophoran mollusc found in the Arctic Ocean and the North Atlantic Ocean. It was first described by the Danish missionary and naturalist Otto Fabricius.
