How do biologists classify the vast diversity of the animal kingdom?
In short: Explore the fundamental traits that define animal life. This video tours nine major phyla, examining the essential vocabulary used to distinguish between different species and body plans.
The presentation covers key biological concepts such as symmetry, cephalization, and the distinction between protostomes and deuterostomes. It also explores the presence of a coelom in various organisms.
The tour traverses nine major animal phyla, eight of which are composed entirely of invertebrates. The video also highlights fascinating exceptions, such as echinoderms, like the sea star, which possess bilateral symmetry as larvae but typically exhibit radial symmetry as adults.
