The simplicity of design and the efficiency of sharks underwater makes it evident why sharks have survived on earth for millions of years. The impact of people on sharks is undeniable and sad. If we lose these majestic animals we will lose alot. Apex predators serve a very important purpose in nature. I hope we do not push them to extinction. Here is a short clip demonstrating their ability to move efficiently through the water.
The sharks that are feed in Nassau Bahamas are grey reef sharks. Even though they are not overly aggressive, they do lose teeth trying to grab and chew on the bits of chum. In a way this image does reflect the level of interest that you may find on many dives. Some divers will absorb all of the available information about the dive, while others appear to be rather bored or disinterested.
On our first shark dive in Nassau Bahamas we were heading to the bottom. The grey reef sharks were starking to come into the dive site, but were very hesitant to mingle with a relatively large group of divers, 23 or so divers were in our group. So while the sharks were trying to determine if they wanted to check out our group I came across a hawksbill turtle at about 40 feet. He was heading to the surface so I followed him up for a while before I could get him between me and the sun. I thought about turning off the stobes so he would be only visible as a silhouette. But, decided his shell would add interest to the image.
