acquarium antics
A octopus has caused havoc in his aquarium by performing juggling tricks using his fellow occupants, smashing rocks against the glass and turning off the power by shortcircuiting a lamp.
"Otto is constantly craving for attention and always comes up with new stunts so we have realised we will have to keep more careful eye on him - and also perhaps give him a few more toys to play with."
"What was happening in the aquarium was a mystery. Each week, keepers were finding shark carcasses in the bottom of the tank. Week after week, the 3-4 foot sharks kept vanishing. So, one night, someone stayed up to see who the culprit was."
