Terrapin by name, terror by nature - this female yellow-bellied slider terrapin, dubbed Tina, had to be found a tank of her own at the Hunstanton Sea Life Sanctuary after terrorising the other occupants.
Despite being no bigger than a dinner plate, Tina managed to bully her tankmates - three razor-toothed caiman crocodiles called Jabuti, Wanadi and Kacheri, who are all about 4ft long.
Adam Makinson from the sanctuary said: 'They are Cuvier's dwarf caimans, but though much smaller than other crocodiles they are plenty big enough to bite Tina in half if they wanted to.
'Instead, Tina has been stealing the mice and chicks the caimans are fed, and was spotted biting Wanadi on the back twice.'
Tina was an unwanted pet donated to the sanctuary over a year ago.
Mr Makinson added: 'Terrapins are frequently bought as pets when cute and tiny, and end up needing re-homing because their owners don't realise how big they grow and how much care they need.
'It's been a huge problem ever since the Teenage Ninja Turtles first appeared on our TV screens. We must have taken in at least 50 in the last 10 years.'
Tina and two other terrapins had cohabited peacefully with the caimans for months until she turned nasty.
'Why Tina suddenly developed a hankering for the larger meals intended for the caimans is a mystery, but she was not going to be denied,' Mr Makinson added.
