M-Bay’s unusual walk-through aquarium is home to 2000 submarine beasties, including jellyfish, moray eels, stingrays and, yes, some sharks. Other rare and endangered toothy reptiles on display include some of the world’s last remaining golden crocodiles. A staff of scuba-diver caretakers and naturalists are available to chat as you wander around. Better yet, go scuba diving yourself (from $650).
