Another reason why sharks should be held in captivity is if they are on the verge of going extinct but other than that just leave the sharks where they are. If the aquarium did not buy them, they would have been dead anyways. While Doctor Carson and his team of scientists have their theories on why Ralph and Norton died, I have mine on why a whale shark in the wild died; how about the trash that your cruise line dumped over board. Whale sharks (Rhincodon typus) are the largest shark, and indeed largest of any fishes alive today. I do not believe that there should be complete blame on the Georgia Aquarium on the death of the sharks. It is better for the sharks to stay at the aquarium if theyre going to fed, cared for, and promote knowledge to others.

The most significant difference between whale sharks and humans is that they live in the sea, and we live on land.
