Both are filter feeders. Good thing sharks arent human. My posting, "Texting As Killer, As Savior" generated strong interest and I wanted to share some more compelling graphic designs from Dr. Robin Landa's Wiley Student Advertising Design Challenge, "Texting and Driving Don't Mix." [9], On 7 February 2012, a large whale shark was found floating 150 kilometres (93mi) off the coast of Karachi, Pakistan. Sometimes trying to establish connections lead to programs like diving with the sharks.

They are not the ones to blame; they have taken the proper procautions in order to make sure they were taken care of. [64], Despite its size, the whale shark does not pose any danger to humans. The article isn't online yet (read it on the iPad! Lily Goldsmith from Valencia CC. [10][11][12], Evidence suggests that males grow faster than females in the earlier stages of life but ultimately reach a smaller maximum size. I know they did a few years ago, but I thought they released it. The most significant difference between these two sharks is how they feed. No reasonable doubt that the last individual has died, Known only to survive in cultivation, in captivity or as a naturalised population, Facing an extremely high risk of extinction in the Wild, Facing a high risk of extinction in the Wild, Likely to qualify for a threatened category in the near future, Does not qualify for Critically Endangered, Endangered, Vulnerable, or Near Threatened. " if papers were being produced and published, I could at least understand the case for keeping such animals in captivity.". I think zoos and aquariums should have to meet some basic threshold of knowledge before they are allowed to keep certain species. When the issue originally came up, I remember expressing my outrage to a friend of mine and his response was "Well, how are we ever going to learn to keep them if we don't try?" The one thing that I dont agree with about holding animals in captivity is the fact that in most cases we hinder them from their natural instincts. Despite the aquariums progress, there are still concerns about the animals welfare. I believe sharks should only be held in captivity if its better for that shark and they have a better chance of living longer. A study. NOTE: This blog has moved. The Georgia Aquariums whale shark exhibit is unique and I see no harm in its existence. They are globally distributed, and we even have them (sometimes) here in South Carolina. New research shows there is no difference in life expectancy between killer whales born at SeaWorld and a well-studied population of wild killer whales. There are organizations out there that nurse animals back to health and release them into the wild. "The expectation is that if you put a whale shark in an aquarium, it's a death sentence.". I agree with Sweetwater Tom. No proof of anythingsimply anecdotal and also doesnt prove me right either.

Also, they have the weight and mass of a school bus, and we are 50-100 kg creatures. About 95% of the oscillating period was spent in epipelagic depths (<200 metres (660ft)), but whale sharks also took regular deep dives (>500 metres (1,600ft)), often descending in brief "stutter steps", perhaps for foraging. As a result, animal welfare activists have called for an end to marine parks, roadside zoos, and aquariums that keep ocean animals in captivity.

If they had died in the wild though they would not have people researching and scrutinizing every factor that could have lead to their death, which is beneficial to the other whale sharks. If no-one can see sense on this, maybe they should stop acting like they know better and research on animlas, conservation, bio-diversity and the need that animals have in the wild that can not be met in captivity. That being said, we must be careful about assigning human emotion to these animals (the same goes for captive killer whales and dolphins).
