Evaluate Basic External Animal Anatomy and Morphology - AgriSETA

Evaluate Basic External Animal Anatomy and MorphologyPrimary Agriculture NQF Level 1 Unit Standard No: 1161737Two of the five kingdoms are very important for Agriculture: the Plant Kingdom andthe Animal Kingdom. The purpose of this Unit Standard is to study the AnimalKingdom.For the purpose of this Unit Standard the external anatomy (outside parts of thebody) and morphology (the science of the forms and structures of organised beings)of the five Vertebrate (having a vertebral column) groups (classes) and three ofthe Invertebrate (any animal that has no spinal column) groups (classes) will beexamined. The first two invertebrates are grouped together and are part of the socalledArthropods (jointed legs). The third Invertebrate that we will look at iscalled mollusca, or animals with a soft body. The mollusca are a big group of softbodiedanimals that form the phylum mollusca with a few classes. One of theclasses is the snail (Gastropoda).It is necessary to study the anatomy and morphology of a few different animals togive you an understanding of the differences between animals and to show youwhat to look for when studying differences in animals. The different animals that arestudied are easily available and illustrate the basic anatomic differences. It is notnecessary for you to study every animal that is included, but the external anatomythat classifies an animal in a certain class must be explained.In the agricultural world it is sometimes necessary to have knowledge of animalssuch as insects, fish, snails and reptiles. Snails, ticks and other insects aresometimes responsible for losses in small and large animal stock and can alsodestroy their fodder.Other animals like fish and reptiles can also become a farming possibility.Session 3 of this guide is very important because it will enable you to see theresemblance between farm animals and other animals in different classes.Vertebrate:Invertebrate:Arthropods:Mollusca:Is a subphylum of the Phylum Chordata comprising all animals that havea vertebral column (spinal column), including mammals, birds, reptiles,amphibians, and fish.Animal that has no spinal column.Animals with jointed legs.Animals with a soft body.Version: 01 Version Date: July 2006
