GENERAL CHARACTERS & CLASSIFICATION OF MOLLUSCA. Phylum Annelida is divided into four main classes, primarly on the basis of setae, parapodia, metameres and other morphological features. Class 1 Polychaeta (Polys: many; chaite:hair) Habitat: They are marine, terrestrial, and freshwater. Classification of Animal Kingdom - Porifera, Coelenterata, Platyhelminthes, Aschelminthes, Annelida, Arthropoda, Mollusca, Echinodermata, Chordata.] Animal Classification In order for us to understand how all living organisms are related, they are arranged into different groups.The more features that a group of animals share, the more specific the group is. Gastropod - Gastropod - Classification: Since the 1980s, gastropod classification has been the subject of extensive debate. The references in that work have not been transferred to this one. There are 11 classes of mollusks in the Mollusca phylum. Phylum Annelida is divided into four main classes, primarly on the basis of setae, parapodia, metameres and other morphological features. Ruppert and R.D. Disclaimer: The Animal Diversity Web is an educational resource written largely by and for college students.ADW doesn't cover all species in the world, nor does it include all the latest scientific information about organisms we describe. ADVERTISEMENTS: In this article we will discuss about the classification of phylum chordata with its characters. This phylum can be segregated into seven classes: Aplacophora, Monoplacophora, Polyplacophora, Bivalvia, Gastropoda, Cephalopoda, and Scaphopoda. Classification in Outline (Up to Orders): The classificatory scheme followed in the present text is based largely on the plan laid down by E.E. ADVERTISEMENTS: 2. CHAPTER 4 ANIMAL KINGDOM Animal Kingdom is characterized by multicellular, eukaryotic organisms. The classification helps to assign a systematic position to newly described species. ADVERTISEMENTS: In this article we will discuss about the general characters and classification of Phylum Mollusca. Habitat: mostly marine; They burrow in mud and sand. Class 1 Pelecypoda or Bivalvia. Classification of Phylum Annelida. Phylum Chordata belongs to the Kingdom Animalia and includes all the vertebrates, i.e., animals with a backbone, and several invertebrates, i.e., organisms without a backbone. Class MONOPLACOPHORA, Ex. This class comprises snails and slugs from saltwater, from freshwater, and from the land. Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. Phylum MOLLUSCA. Although the phylum Mollusca are made up of a set of incredibly diverse animals, there are certain characteristics which aid to classify them. Class 1 Polychaeta (Polys: many; chaite:hair) Habitat: They are marine, terrestrial, and freshwater. General Characteristics and Classification of Arthropoda Arthropoda (Arthon- Jointed; podos- legs) Arthropoda, animals having jointed appendages or legs. The Moiluscans are soft bodied, triploblastic coelomate & bilaterally symmetrical animals. The gastropods (/ ˈ ɡ æ s t r oʊ p ɒ d z /), more commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca, called Gastropoda. Order Decapoda, Ex. Class Gastropoda Subclass Prosobranchia. Barnes (1994) in their book “Invertebrate Zoology”. Order Archaeogastropoda Source | Credits | Picture Credits: NCERT General Science Basis for Animal Kingdom Classification Classification of Animal Kingdom is based on various fundamental features like - Levels of Organisation, Symmetry, … Mollusca is a phylum that is classified under the super phylum Lophotrochozoa, in the Animal kingdom. Many, however, occur in fresh water and some even in damp soil. The cells lack cell ... About 1.2 million species of animals are described till now. It is a phylum of triploblastic, haemocoelomic, segmented invertebrates having head, thorax and abdomen, a chitinous exoskeleton and jointed legs and appendages. No distinct head Classification of Mollusca up to subclasses and orders and examples. Genera represented in Benton collection: Mopalia . Introduction :Mollusca includes soft bodied animals .It was first applied by Ariistotle to the cuttle-fish of the Aegean Se. Habitat: They are mostly marine. The chordates form a large heterogeneous group of members differing widely from one another in many respects. From most broad to most specific, these categories are kingdom, phylum, class, order, family, genus and species. Phylum Mollusca is a very diverse (85,000 species ) group of mostly marine species, with a dramatic variety of form. The Moiluscans are soft bodied, triploblastic coelomate & bilaterally symmetrical animals. Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. Mollusks refer to are a large group of soft-bodied invertebrate animals. GENERAL CHARACTERS & CLASSIFICATION OF MOLLUSCA.
