Zoology (45 marks) · Animal diversity and classification

Useful for: OSSC RHT — Regular High School Teacher

Overview

Animals are classified into phyla by body plan, symmetry, body cavity and other features; binomial names give each species a unique name.

Key points

  • Linnaeus introduced binomial nomenclature (genus + species).
  • Whittaker proposed the five-kingdom classification in 1969.
  • Major phyla: Porifera (sponges), Cnidaria (jellyfish), Platyhelminthes (flatworms), Nematoda (roundworms), Annelida (earthworm), Arthropoda, Mollusca, Echinodermata (starfish), Chordata.
  • Arthropoda is the largest animal phylum.
  • Vertebrate classes: fishes, amphibians, reptiles, birds, mammals.
  • Features used: symmetry, germ layers, body cavity, segmentation.

Explanation

  • Echinoderms are exclusively marine.
  • Mammals have mammary glands and hair.
  • Birds are warm-blooded and have feathers.
  • Amphibians live both in water and on land.
  • Classification shows evolutionary relationships.

Step by step
