<h1 class="shark-header">Know about Sharks</h1>
<p class ="shark-text">
Sharks star in blockbuster movies as blood-seeking villains,
but in reality they’re far more fascinating and complicated than they’re often depicted in pop culture.
<br>
<img class="shark-image" src="img/shark-1.jpg">
<br>
Based on fossilized teeth and scales, scientists believe that sharks have been around for more than 400 million years—long before the dinosaurs.
The ocean’s top predators have evolved into roughly 500 species that come in all different sizes and colors and have varying diets and behavior.
</p>
<h2 class="shark-header">Anatomy</h2>
<p class ="shark-text">
Like rays and skates, sharks fall into a subclass of fish called elasmobranchii. Species in this subclass have skeletons made from cartilage,
not bone, and have five to seven gill slits on each side of their heads (most other fish have only one gill slit on each side),
which they use to filter oxygen from the water.
<br>
<img class="shark-image" src="img/shark-2.jpg">
<br>
Formidable predators, sharks have mouths lined with multiple rows of individual teeth that fall out and grow back on a routine basis.
Their teeth come in all sizes and shapes, from serrated like a razor to triangular like a spear.
</p>
<h2 class="shark-header">Behavior</h2>
<p class ="shark-text">
Sharks are found in deep and shallow waters throughout the world’s oceans, with some migrating vast distances to breed and feed.
Some species are solitary, while others hang out in groups to varying degrees. Lemon sharks, for example, have been found to
congregate in groups to socialize.
<br>

<br>
Scientists are still trying to figure out how long sharks live and have only studied the ages of a fraction of shark species.
Most notable is the Greenland shark, Earth’s longest-lived vertebrate at 272 years.
<br>
Most sharks eat smaller fish and invertebrates, but some of the larger species prey on seals, sea lions, and other marine mammals.
