How many levels does the animal classification system have?

What is the first thing a scientist does to classify an animal?
The first thing a scientist does to classify an animal is to observe its physical characteristics and behavior to determine its characteristics and identify its unique features. This information is used to place the animal into a specific group or category based on similarities with other organisms.
What does classification of an animal mean?
The classification of an animal refers to the scientific categorization of an organism into a specific group based on its characteristics, traits, and evolutionary relationships. It involves placing the animal into a hierarchical system of classification that includes domains, kingdoms, phyla, classes, orders, families, genera, and species. This classification helps in understanding the relationships between different species and organizing the vast diversity of animal life.
