Once known only from Paleozoic fossils, living monoplacophorans were discovered in 1952 in one of the most important discoveries in modern biology. We have moved all content for this concept to for better organization. A chiton’s shell consists of eight separate plates that overlap to form a shell like a coat of armour along the upper surface of its flat oval body. The name comes from the characteristic presence of 8plates called valves that are overlapping and attached to a part of the mantle called girdle.

The Solenogastres (less often referred to as Neomeniomorpha), common name the solenogasters, are one subclass of small, worm-like, shell-less molluscs (Aplacophora), the other subclass being the Caudofoveata (Chaetodermomorpha). Since that first recent species (Neopilina galathaea) was discovered, around 20 other species have been identified.One reason for having evaded detection for so long is that they are generally found in the deep ocean. POPPE-IMAGES™ has the aim to document the Marine Life in the Philippines. Animal: The animal body is composed of a head, a mantle and a large flattened foot. With the exception of a ventral groove, the mantle covers the entire body. Solenogastres A preserved specimen of Epimenia verrucosa: Scientific classification; Kingdom: Animalia : Phylum: Mollusca: Class: Aplacophora: Subclass: … Class Aplacophora. Examines the classification of mollusks. Temperate Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions Northeast Atlantic and the Mediterranean. Defining Characteristic of Monoplacophora. Possibly representive of the primitive molluscan condition or a secondary reduction from more advanced, shelled ancestors. From scientific Latin Monoplacophora, class name from mono- + ancient Greek πλακο-, πλάξ flat plate, tablet + -ϕόρος, after Polyplacophora. All known modern forms are shell-less: only some extinct primitive forms possessed valves.The group comprises the two clades Solenogastres (Neomeniomorpha) and Caudofoveata (Chaetodermomorpha), which between them contain 28 families and about 320 species. Neopilina galatheae, top (dorsal) view. Mollusks are soft-bodied invertebrates of the phylum Mollusca, usually wholly or partly enclosed in a calcium carbonate shell secreted by a soft mantle covering the body.

Subclass Chaetodermomorpha (Caudofoveata) Worm-shaped; covered by cuticle and … Among the shell-less molluscs ("Aplacophora") there are about 340 of the most primordial molluscs to be found on earth. Number of Species: Catalogue of Life: 2019 Annual Checklist = 28 families, 425 species; Molluscabase = 431. CAVS / CAAB Biocode. Many organisms belonging to this phylum have a calciferous shell. Aplacophora definition is - an order of Amphineura comprising wormlike mollusks in which the body is without calcareous plates but the mantle bears numerous calcified spicules over its entire surface. Apodomenia enigmatica sp. As their scientific name Aplacophora literally states, the members of this group actually are devoid of a shell and in that regard are unique among molluscs.

Environment: milieu / climate zone / depth range / distribution range Ecology Demersal; non-migratory (Ref. The monoplacophora, common name (deep-sea limpets) are a small, but ecologically important group of single-shelled molluscs. Etymology of Aplacophora: A = not or without, Plak = a plate or flat object, Phora = to bear (“Not having a shell”).
