Phylum

A phylum is a way scientists categorize or group living organisms based on their major body structures and features. It’s like a broad family classification that includes many related species sharing common characteristics. For example, all animals with a backbone, called vertebrates, belong to the phylum Chordata. Phyla help scientists organize the diversity of life, making it easier to study how different organisms are related and how they evolved over time. Think of it as a large, natural grouping that reflects fundamental similarities in body design and organization.
