Mopalia muscosa, the mossy chiton, is a species of chiton, a polyplacophoran, an eight-plated marine mollusk. It is a northeastern Pacific species which occurs from British Columbia, Canada, to Baja California Mexico. [1] [2] [3]
This species is found in the middle and lower intertidal zone on exposed rocky shores. Mopalia muscosa can be 40 to 55 mm (1.6 to 2.2 in) in length. Mossy chitons are often covered by algae, barnacles, and limpets. The chiton's girdle is covered with coarse hair-like bristles or "setae".The visible exterior of the chiton's eight shell plates are typically a drab brown or grey-green, however on the underside the shell plates have a vibrant turquoise blue color. Some mossy chitons are biofluorescent mainly around the girdle and may show a bright glowing green color under ultra-violet or blue light. [4] Mossy chitons typically move about at night or when covered by a high tide in order to graze on the red and green algae of which their diet consists. Young chitons have a planktonic stage and later metamorphose and settle on the bottom as adults.
Chitons are marine molluscs of varying size in the class Polyplacophora, formerly known as Amphineura. About 940 extant and 430 fossil species are recognized.
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 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.
Haliotis rufescens is a species of very large edible sea snail in the family Haliotidae, the abalones, ormers (British) or pāua. It is distributed from British Columbia, Canada, to Baja California, Mexico. It is most common in the southern half of its range.
Tonicella lineata, commonly known as the lined chiton, is a species of chiton from the North Pacific.
Tonicella undocaerulea, commonly known as the blue lined chiton, is a species of chiton.
Mopalia spectabilis, commonly known as the red-flecked mopalia, is a species of chiton.
Tonicella lokii, commonly known as the flame lined chiton or Loki's chiton, is a chiton in the lined chiton genus Tonicella.
Mopalia hindsii is a species of medium-sized chiton that grows up to 7 cm long. Most commonly found in intertidal zones, M. hindsii has a white ventral side unlike most intertidal chitons that are orange underneath.
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.
Mopalia ciliata is a chiton in the genus Mopalia, commonly known as the hairy chiton. It is a medium-sized marine mollusc up to 5.0 cm (2.0 in) in length. It is oval shaped with 8 separate, moderately elevated, overlapping ridged valves on its dorsal surface. Hairy chitons can be found along the coast of North America.
Katharina tunicata is commonly known as the black Katy chiton, black Leather chiton, black chiton, or leather chiton,, is a species of chiton in the family Mopaliidae.
Acanthochitona fascicularis is a common chiton in the family Acanthochitonidae.
A girdle is part of the anatomy of a chiton, one class of marine mollusks, the class Polyplacophora. The shell of a chiton consists of eight valves which articulate with one another. The girdle is a strong but flexible structure that in most cases encircles the plates, holding them all together.
Chiton olivaceus, the green chiton, is a species of chiton, a marine polyplacophoran mollusk in the family Chitonidae, the typical chitons.
Enoplochiton echinatus is a Southeast Pacific species of edible chiton, a marine polyplacophoran mollusc in the family Chitonidae, the typical chitons.
Tonicella insignis, the white-lined chiton, or red chiton, also known as the hidden chiton, belongs to the Tonicellidae family in the class Polyplacophora, and the phylum of Mollusca. Its body length of T. insignis is around 5 cm.
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.
