Shark

Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the rays. However, the term "shark" has also been used for extinct members of the subclass Elasmobranchii outside the Selachimorpha, such as Cladoselache and Xenacanthus, as well as other Chondrichthyes such as the holocephalid eugenedontidans.

Why Have There Been So Many Shark Attacks in NC?

It may be a case of "Occam's razor" where the simplest answer is best. There are more people in the water. Global shark populations have actually been experiencing a sharp decline over the past few decades with some estimates suggesting we could be losing 100 million sharks each year! Other factors include low rainfall along the coast that has made the water more salty which both sharks and their prey like and also certain species of shark become agitated above a certain temperature (80 degrees Fahrenheit) and warmer waters are altering their behavior.

Sharks are easily one of the most frequently misunderstood creatures on our planet. They are gentle and shy creatures at nature, the only time they become aggressive is during feeding and mating seasons.
