Q.6 Write a classification essay of around 200 words on any one of the following topic:
Classification essay on Animals It is well-known that there are many different animal species on the earth. Some of them live on a land, while the others are at the sea. But there is still an unknown fact about how many kinds of animal species we have. So scientists have briefly classified them into two categories as vertebrates and invertebrates. All animals belong to one of these groups.
Vertebrates have an internal skeleton made of bone. Most of them have an exoskeleton. Fish, amphibians, reptiles, birds, mammals, primates, rodents and marsupials belong to this group. Even though there are a small number of vertebrates comparing to others’ populations, their size and power enable them to dominate their habitat.
We can cite mammals as an example concerning this matter. There are several unique characteristics of mammals which distinguish them from the others. They can bring fully formed babies into the world and female ones can put their babies to breast for feeding them. They are also the most intelligent living creatures on the earth. They are able to learn to live under hard conditions and adapt many different climates.
Invertebrates are the animals without a backbone. They don’t have an internal skeleton made of bone. Most of invertebrates have a fluid-filled, hydro static skeleton like worm. Others have a hard outer shell, like insects. More than 98% animal species in the world are invertebrates. The protozoa, annelids, echinoderms, molluscs and arthropods belong to this group. The main features of invertebrates are that they are composed of head, thorax and abdomen; so some of them respire through their skin. And they are unable to have babies because they are oviparous animals.
Classification of animals is a key to understand similarities and differences between animals and it provides scientists to explain evolutionary relationships, describe similar features through the various extents of animal groups and subgroups. But we should love all animals and respect their inherent right to life regardless of their species.
