What type of symmetry is exhibited by most echinoderms?
Step 1: Understand what echinoderms are. They are a group of marine animals that include starfish, sea urchins, and sea cucumbers.
Step 2: Learn about symmetry. Symmetry refers to how the body parts of an organism are arranged.
Step 3: Identify the types of symmetry. The main types are bilateral symmetry (where the body can be divided into two equal halves) and radial symmetry (where the body can be divided into multiple equal parts around a central point).
Step 4: Observe that most echinoderms, like starfish, have a body plan that allows them to be divided into equal parts around a central axis.
Step 5: Conclude that this arrangement is called radial symmetry, which is common in adult echinoderms.
