<h1>🔍 Animal Classification Review</h1>
<h2>Week 30 — Friday | Review and Check Your Knowledge</h2>

<h3>✅ Review: Key Concepts</h3>
<div class="reading-box" style="background: #fff3e0; border-left-color: #ff9800;">
<p>Scientists classify animals by their shared characteristics. <strong>Vertebrates</strong> have backbones and include 5 groups: mammals, birds, reptiles, amphibians, and fish. <strong>Invertebrates</strong> lack backbones and make up 97% of all animal species, including insects, arachnids, crustaceans, mollusks, and more. <strong>Metamorphosis</strong> is the process of changing form during development. Understanding animal groups helps us learn how animals live, survive, and relate to each other!</p>
