1. What Defines a Vertebrate and Invertebrate?
The classification of animals into vertebrates and invertebrates depends on the presence or absence of a backbone or spinal column.
Vertebrates: Animals with a backbone, including mammals, birds, reptiles, amphibians, and fish.
Invertebrates: Animals without a backbone, comprising the vast majority of animal species, such as insects, mollusks, and crustaceans.
Fruit flies, scientifically known as Drosophila melanogaster, fall into the invertebrate category due to their lack of a vertebral column. They are insects, characterized by their exoskeleton, three-part body (head, thorax, and abdomen), six legs, compound eyes, and antennae.
2. What Are the Key Characteristics of Fruit Flies?
Fruit flies possess several distinguishing features that set them apart from vertebrates:
2.1. Physical Attributes
- Size: Typically 2.5 mm long.
- Body Plan: Three segments – head, thorax, and abdomen.

- Exoskeleton: A hard, protective outer covering made of chitin.
- Compound Eyes: Eyes composed of multiple lenses, providing a wide field of vision.
2.2. Biological Traits
- Short Life Cycle: Completes its life cycle in about 10-14 days.
