Did you know that…
- …sharks have tooth-shaped scales called denticles, and that these allow the sharks to move faster and more smoothly in the water? The denticles also prevent the algae and barnacles from accumulating on the shark’s skin.
- …a female shark can get pregnant without ever touching a male shark? This is called parthenogenesis. Only very few cases of parthenogenesis have been documented, though.
- …the eating habits of sharks are affected strongly by the ocean tides. Depending on the phase of the moon, sharks move closer to the shore to catch their prey.
- …there is a tiny shark species that is a mere 8 inches (20 centimeters) long? Pygmy sharks are among the tiniest in their family and they can produce their own light to help them hunt in deep waters.
