The appeal of the aquarium means you see the wonders of the ocean, without any of the danger. Or at least in most cases...
Onlookers at the Orient shopping centre in Shanghai were extremely unlucky when a glass wall cracked, pouring out the contents of the aquarium.
Three lemon sharks, several turtles and small fish were sadly killed in the incident, and sixteen people are said to be injured.
In 2010, a 2.6m-gallon tank - one of the of the largest in the world - also cracked in Dubai.
A true horror moment for selachaphobiacs and ichthyophobiacs.
