Phylum Arthropoda comprises 75% of animal diversity! True compound eyes are absent. Members of subphylum Uniramia have uniramous appendages and bear one pair of antennae, a pair of mandibles, and two pairs of maxillae (one pair of maxillae in milli- pedes) on the head. 7. Grow by molting. The head has a pair antennae and ocelli. Cell Specialization Organ Systems ; 5. The thorax bears the wings as well as six legs in three pairs. 3. Hickman Fig. 2- The mouth parts on ventral side of the head, and the mandibles are unjointed and have no palps. 6. Describe the characters and classification of sub-phylum Uniramia. Ø Body is divided into head, thorax and abdomen. Because of the unbranched nature of the appendages of its members, the subphylum is designed uniramia, as against those of crustaceans and primitive chelicerates that are branched and hence biramous. chele=claw, keros=horn) The body is divided into cephalothorax and abdomen with no distinct head. There is usually a great proportion of insects present in striking con- In this exercise we will omit the small classes Symphyla and Pauropoda, and focus on the centipedes, millipedes, and insects, beginning with the least specialized tracheates, the Chilopoda. Subphylum Uniramia (Myriapoda) a) Class Chilopoda –centipedes b) Class Diplopoda –millipedes c) Class Insecta - insects. Subphylum Uniramia Class Insecta Subclass Pterygota Division Endopterygota • Ants, bees and wasps • All have four wings • Many eusocial species. 5. Myers, P., R. Espinosa, C. S. Parr, T. Jones, G. S. … Body Cavity Coelom - true open space ; 3. Cephalothorax bears six pairs of appendages with no antennae or antennules. Subphylum Crustacea – Class Crustacea - crabs, crayfish, shrimp 3. This has to do with their method of sex determination, called Haplo-diploidy. List of animal phyla is a list of the major groups of animals usually classified as a phylum.Modern sources have been used: the list is different from that of Linnaeus or Cuvier.A list of this type may be arranged alphabetically; equally it might be arranged according to evolutionary relationships. Describe the characters and classification of sub-phylum uniramia. The uniramians have mandibles which are non - jointed, unbranched appendages … However, the competing hypothesis — that Crustacea and Hexapoda form a monophyletic group, the Pancrustacea , to which the Myriapoda are the closest relatives — has support from molecular and fossil evidence. The name Hexapoda denotes the presence of six legs (three pairs) in these animals as differentiated from the number of pairs present in other arthropods. Segments grouped into 2 or 3 regions known as Tagmosis iii. In this exercise we will omit the small classes Symphyla and Pauropoda, and focus on the centipedes, millipedes, and insects, beginning with the least specialized tracheates, the Chilopoda. Unfertilized eggs become males (drones for reproduction only). Characters :- (i) Appendages are uniramous. Discuss the different larval forms found in echinoderms. •Huge group > 1,000,000 species. Class :- Diplopoda. Classification of Phylum Arthropoda Habitat: They are mostly aquatic, few are terrestrial and very few are parasitic. Insects are invertebrates grouped in the phylum Arthropoda (Arthro-joint, poda-foot) and subphylum Uniramia. Insects are invertebrates grouped in the phylum Arthropoda (Arthro-joint, poda-foot) and subphylum Uniramia. Atelocerata is a proposed clade of arthropods that includes Hexapoda (insects and a few related taxa) and Myriapoda (millipedes, centipedes, and similar taxa), but excludes Crustacea (such as shrimp and lobsters) and Chelicerata (such as spiders and horseshoe crabs).The name is currently used interchangeably with Tracheata. Salient Features of arthropods Insects are invertebrates grouped in the phylum Arthropoda (Arthro-joint, poda-foot) and subphylum Uniramia. Chelicerates (Chelicerata) are a group of arthropods that includes harvestmen, scorpions, mites, spiders, horseshoe crabs, sea spiders, and ticks.There are about 77,000 living species of chelicerates. Classification of Arthropoda. Arthropoda is the largest phylum of invertebrate animals and comprises crustaceans, insects, arachnids (spiders and scorpions), and other classes.Some arthropods have soft-bodied young … I—4 Chapter I— The Zoobenthos of Freshwaters- An Introduction Introduction The benthic animals inhabiting lakes constitute an extremely diverse assemblage, both tax-onomically and ecologically.

Animals • ~ 84% of all animal species Renewable chitinous exoskeleton 4. Class :- Merostomata. Species live in colonies and only a few individuals reproduce. "Uniramia" was a taxon based mainly on an erroneous "ground plan" of the arthropod leg and mandible, and should be completely dropped from use. Characters :- (i) A pair of externally jointed appendages is usually present in each segment. Insects are invertebrates grouped in the phylum Arthropoda (Subphylum : Uniramia) Characters of the Phylum Arthropoda: (Arthro-joint, poda-foot) i. Segmented body ii. Characters of the Phylum Arthropoda are 1. A. Subphylum Uniramia. Tagmata are head and trunk in myriapods and head, thorax, and abdomen in insects. Segments grouped into 2 or 3 regions (tagma) known as Tagmosis. Insecta is the largest class of the world's largest phylum. General characteristics of Insects (class):- Insects are the most successful life form on the planet: they make up more than half of all living things on Earth- Some experts suggest that there are more than 10 million insects- Divided into 29 orders Subphylum: Uniramia Mainly terrestrial animals Includes myriapods (centipeds, millipeds) and insects General characters: 1- The body composed of head and elongated trunk. 3.
