<p>Monotremes are a living relic of mammalian history, representing an ancient branch of mammals that split from other species millions of years ago. Despite their reptilian traits—such as laying eggs—they are warm-blooded, produce milk, and have fur. The two most famous monotremes are the platypus and the echidna.</p>
<h3>The Platypus</h3>
<p>The <strong>platypus</strong> is an iconic animal of Australia, known for its duck-like bill, webbed feet, and electroreception, which it uses to detect prey in murky waters.</p>
<h3>The Echidna</h3>
<p>The <strong>echidna</strong>, on the other hand, is a spiny, burrowing insectivore with a long, sticky tongue perfect for catching ants and termites.</p>
<p>Both species are vital to their ecosystems, and due to habitat loss, they are increasingly in need of protection.</p>
