“I challenge you to investigate these issues on your own. The facts are out there and are easily accessible. Everyone should become aware and take their own educated stance regarding the decline of sharks worldwide.”
Sharks – arguably the most dominant group of predators on our planet. They are stereotyped as voracious animals; equipped with large jaws and teeth that frighten most people. In truth, sharks are a very dynamic group of animals, and science has found these species to be of serious ecological significance to maintaining healthy oceans.
There are approximately 500 species of sharks worldwide. They range in size from a few inches to tens of feet long. Furthermore, sharks differ in their predation strategies (hunt and chase, surface predation, ambush), antipredator techniques (camouflage, escape maneuvers, armor), migration, appearance, abundance, behavior and performance. The diversity and density of shark species is strongly influenced by their respective habitat niche: depth preferences, levels of dissolved oxygen, and temperature variances within the oceans.

Sharks have been swimming the seas for 420-455 million years, and are considered an evolutionary success, as they have circumvented five major extinctions. This blog provides me with an opportunity to look past their typical stereotypes and see what sharks are really about. I am here to do the research for you, and provide you with the facts. Through the use of figures, videos and text we will explore different topics to help raise your awareness.
I am very keen on making this blog appealing to you. Please comment on any topics that you would be interested in learning about below. I look forward to learning more about these amazing animals with you.
