Recent sightings of four great white sharks have prompted a swimming ban for the rest of the Labor Day weekend at some of the area's Oceanside beaches, including North Beach, Lighthouse Beach, South Beach and Harding Beach and Nauset Beach.

       No swimming this Labor Day weekend and maybe for another month.  The Great White Sharks have moved in and are enjoying the ideal water temperatures and the abundant fresh food, in the form of seals.  They do not care if you planned a beach weekend retreat, are there on your first vacation in years, or if you are going back to school tomorrow.  They are doing what sharks do and they are doing it very well.

     The Great White is between 12-16 feet long, and can grow up to 19-21 feet. The Great White is the most feared fish for humans. Great White Sharks are a very large species of shark. They are streamlined swimmers, and have a torpedo-shaped body with a pointed snout.

     They have about 3000 teeth, arranged in several rows. The first two rows of teeth are used for grabbing and cutting prey, while the teeth in the last rows rotate into place when front teeth are broken, worn down, or fall out. The teeth are triangularly shaped with serrations on the edges. (How cool is that!)

     The back of the shark is a dull grey color and the underside is colored white. They have three main fins: the dorsal (on back) and two pectoral fins (on the sides). The tail is crescent shaped. There are five  gill slits on Great White Sharks. The Great White reaches maturity about 9 years after it's birth. The growth of The Great White shark is about 25-30 cm per year. The White Shark has litters of about 7-9 pups. The females only reproduce twice in her whole life.
