ok...that makes sense now. But...for the average (non-fishy) person, whose going to think that? Now that I put more brain power that direction, physics says that yes, a shark can leap out of the water (assuming air resistance is equal to 0

). But, I believe the biologists were looking to see if the sharks breached for prey purposes (specifically dolphin calves)...which was not answered. Additionally the (less showed) other team of biologists did tag a shark and note it's max velocity, which is pretty cool seeing that I didn't know that before.
Well why not show them the good setups? People try to mimic what other people do all the time, just take a look at all the Takashi Amano inspired nature aquariums out there! Show them the good that people do, rather than the "Tanked" inspired bad ones. Maybe I haven't been to many "bad" public aquariums, but the ones that I did go to (Georgia, Waikiki, New England, and Ripley's), had suitably sized aquariums for all of their inhabitants.And as for private aquariums, have you been to the Sharks and Rays forum lately? Sure, there are stupid questions, but at least those get smart answers. Yeah, the smallest sharks should really be given 250+ size oval aquariums, but still. If somebody is willing to do so, and are for the animal's welfare while in their care, then why not?
