FAQs on Classification of animals Video Lecture - Lucent for GK - UPSC
1. What are the main classification groups for animals? |
|
Ans. Animals are classified into various groups based on their characteristics, including vertebrates (animals with a backbone) and invertebrates (animals without a backbone). Vertebrates are further classified into fish, amphibians, reptiles, birds, and mammals, while invertebrates are classified into various groups such as arthropods, mollusks, and worms.
2. How are animals classified into the arthropod group? |
|
Ans. Arthropods are a diverse group of animals that include insects, spiders, crustaceans, and centipedes. They are characterized by having a segmented body, jointed appendages, and an exoskeleton. Arthropods are further classified into different classes based on their characteristics, such as insects (six legs, three body segments), arachnids (eight legs, two body segments), and crustaceans (multiple pairs of legs, usually with a hard shell).
3. What are the different classes of vertebrates? |
|
Ans. Vertebrates are animals with a backbone and are classified into different classes based on their characteristics. The main classes of vertebrates include fish (aquatic animals with gills and fins), amphibians (animals that live both in water and on land and undergo metamorphosis), reptiles (cold-blooded animals with scaly skin), birds (warm-blooded animals with feathers and beaks), and mammals (warm-blooded animals that nurse their young with milk).
4. How are mammals further classified? |
|
Ans. Mammals are a diverse group of animals, and they are further classified into different orders based on their characteristics. Some of the main orders of mammals include primates (including humans and apes), carnivores (such as lions and wolves), rodents (including mice and squirrels), and cetaceans (including whales and dolphins). Each order has its own unique characteristics and adaptations.
5. What are the main characteristics used to classify animals into different groups? |
|
Ans. Animals are classified based on various characteristics, including their body structure, presence or absence of a backbone, mode of reproduction, and other specific features. These characteristics help scientists categorize animals into different groups and understand their evolutionary relationships. Some of the main characteristics used for classification include the presence of a backbone (vertebrates vs. invertebrates), body symmetry, type of skeleton, mode of reproduction (laying eggs vs. giving birth), and specific adaptations for survival.
