She seems to have some, I've got a new article in the latest Wired on the science of stress, as seen through the prism of Robert Sapolsky. If we could get a more diverse crowd in the aquarium to begin with, I think this newly exposed crowd could see what an impact they could make in this great science. To work around this, Ioworld has a special practice in place. The way the Georgia Aquarium does the program seems safe.

As such, the conditions of captivity may be too restrictive for the whale sharks natural behavior, leading to physical and psychological distress. Happiness is a complex emotion probably not capable in fish, just based on the structure and processing capabilities of the brain.

[22], The whale shark is the largest non-cetacean animal in the world. Dr. Carson generously supported his response to the deaths of Ralph and Norton, and assured us that these deaths were not in any way correlated to maltreatment in the aquarium, so yes, I am satisfied with his statement.

While I can sort of understand the arguments used promoting the keeping of some wildlife in captivity and the greater good is serves, I also do not agree totally on the notion that seeing things in captivity live necessarily motivates kids to become something in later life. The main difference between these two giants is that they inhabit regions of the oceans. If you can, please help me see this differently. "Yes, so long as papers are being published, anything whatsoever should be allowed". WWF experts continue to study shark habits and gather information in the Coral Triangle on individual sharks by using satellite tags, sonar devices and digital cameras. Sometimes trying to establish connections lead to programs like diving with the sharks. Data deficient LC NT VU EN CR EW EX Least Concern Extinct. I also think the interview with Dr. Carlson was great! It is not satisfied and it will not be oppressed. -Edwin Hubble Blackfish tells of the story behind Tilikum, the killer whale that is being held captive at Sea World.
