Sharks

I hate going to beaches because my fear that I'll be eaten from sharks. They're part of the subclass, Elasmobranchii, and they generally have tough skin, typically gray in color, and have tooth like scales.Many sharks have multiple rows of teeth, which consist of lower rows being pointed and upper rows being triangular shape. their teeth are engineered to consume their pray

Here are some interesting facts about sharks:

	Many sharks can see well in dimly lit environments, have excellent night vision, and can differentiate between colors. A reflective film of tissue called a tapetum is found on the back of sharks' eyeballs. This allows sharks to see incredibly well in low-light conditions.
	Sharks are devoid of muscles. Instead, they filter oxygen from water by their gills.
	sharks can have up to 50,000 teeth in their lifetime.
