Sea urchin walks on its teeth<\/h1>\n\n\n\n

Have you ever seen a creature with no face, no eyes, and no tail\u2014just a spiky ball on the bottom of the sea? It's a sea urchin. At first glance, it looks like an ordinary spiky rock. But inside this ball, there are real wonders.<\/p>\n\n\n\n

The sea urchin has no head. But underneath, right in the center of its body, is a mouth with five hard "teeth." Scientists call this special mouth "Aristotle's lantern" - because 2,300 years ago, the ancient Greek scientist Aristotle described how it looked like an ancient lantern. The five teeth converge in the center and grow continuously throughout its life - they wear down on rocks and grow back again. With them, the urchin scrapes algae from the rocks like a tiny grater.<\/p>\n\n\n\n

But how does a hedgehog walk if it doesn\u2019t have legs? It does! Hundreds of tiny transparent legs-suction cups are hidden between the spines. With them, the hedgehog slowly walks along the bottom and even climbs onto rocks. And the spines themselves move - it can rotate each one individually, like thousands of small needle-antennae.<\/p>\n\n\n\n

Some species of sea urchins live up to 200 years! They are the longest-lived among invertebrates. Imagine: a small spiky ball at the bottom saw how ships with sails sailed 200 years ago, how the seas and continents changed.<\/p>\n\n\n\n

It's easy to mistake a hedgehog for a lifeless stone. But life beats inside it - ancient, slow, wise. Nature reminds us: beauty and miracles come in the most unexpected forms.<\/p>\n\n\n\n
