Arthropods constitute the largest group of the animal kingdom. Give reasons.

Explanation

### Step-by-Step Solution:

1. **Definition of Arthropods**: Arthropods are a diverse group of invertebrate animals that include insects, arachnids, myriapods, and crustaceans. They are characterized by their jointed limbs and segmented bodies.

2. **Dominance in Species Count**: Arthropods represent the largest group of animals in terms of species diversity. It is estimated that about 80% of all known animal species are arthropods, particularly insects.

3. **Undiscovered Species**: There are still many species of arthropods, especially insects, that have not yet been discovered. This suggests that the actual number of arthropod species may be even higher than currently documented.
