Classification of Insects:   Classification of insects is basically adopted by A.D. Imms (1957) , according to him class Insecta or Hexapoda is divided into two sub classes Sub Class 1- Apterygota:   Apterous insects, the wingless condition presumed to be primitive, metamorphosis slight or absent. Adult with one or more pair of pregenital abdominal appendages. Adult mandible usually articulating with the head capsule at a single point. This sub class is divided into following four orders Thysaneura: Example Silver fish  Diplura: Example Japygids Protura: Example Telson tails or proturans   Collembola: Example spring tail Sub Class 2–Pterygota:   winged or secondarily wingless insects, metamorphosis varied, Adults without pregentital abdominal appendages. Adult mandible usually articulating with the head capsule at two points. This subclass is divided into following two divisions - Division I - Exopterygota:  Wings develop externally. Metamorph...

Phylum Arthropoda

Image
  Arthropoda 👉Arthropods were first studied by  Aristotle.  It is the  largest phylum in the animal kingdom.   Von Siebold   first   coined the term  Arthropoda . 👉It is derived from the  Greek word  Arthos means jointed and podas means legs. It is the largest Phylum of animal Kingdom. At least 80 percent of all known species of animals are arthropods. General characters of  Arthropoda 👉 Arthropodas are  found in aquatic, terrestrial and aerial forms. Some are ecto-parasitic and vectors of disease. 👉 Arthropodas b ody have jointed appendages or legs (which are modified to different structures to perform different functions like jaws, gills, walking legs, paddle). There may be 3 pairs, 4 pairs, 5 pairs, many pairs.  Body is triploblastic,  Bilaterally symmetrical.  👉  Body is divisible into 3 parts tat is  head, thorax and abdomen . NOTE: In some  Arthropodas body is divisible into cephalo...

Classification of Animal Kingdom (Module-2)

Image
  Classification of Animal Kingdom Animal Kingdom is classified into different phylum that is   i)  Porifera  ii)   Coelenterata (Cnidaria)  iii)  Ctenophora   iv)  Platyhelminthes  v)  Aschelminthes (Nemotoda)  vi)  Annelida  vii)  Arthropoda  viii)  Mollusca   ix)  Echinodermata  x)  Hemichordata and   xi)  Chordata The brief discussion of the given phylum are i) Porifera: Porifera   includes arr those organisms which have holes. Porifera animals  are primitive multicellular animals and are  cellular level of organisation .  👉Porifera are non-motile animals attached to some solid support.   Poriferas  are commonly called  sponges . 👉 G enerally marine & mostly  asymmetrical animals .  Sponges have a water transport or  canal system .  Water enters through minute  pores (ostia)  in the bo...

Basis for Animal Kingdom Classification (Module-1)

  Basis for Animal Kingdom Classification Classification of Animal Kingdom is based on the various characteristics are fallowing i)  Based on the Organization Levels ii)  Based on the Symmetry Levels iii)  Diploblastic and Triploblastic Levels  of  Organizations iv)  Based on the Coelom development v)  Based on the Segmentation of the body vi)  Based on the Presence or absence of Notochord.   brief discussion of the fallowing level of classification- i) Based on the Organization Levels:   All the members of Animalia are multicellular, and all the animalia do not have the same pattern of organization of the cells. For Ex. in sponges the cells are arranged as loose cell aggregates . In Coelenterates, the organization of cells is more complex. In animals such as, Arthropods, Annelids, Echinoderms, Molluscs and Chordates, organs have organized to form functional systems, each system is concerned with a specific physiological function. T...
