Portland Aquarium, a December 2012 addition to Milwaukie, introduces visitors to thousands of waterborne species. Guests can slide their hands along the smooth flesh of a stingray or the knobby arms of a starfish or engage in staring contests with leopard sharks and jellyfish. Other exhibits include a cold-water tank filled with fish native to Oregon's coast and a rainforest-themed jungle gym for children. The tropical touch-tank woos visitors with its displays of vibrant-color aquatic life while amphibious wonders, including poison dart frogs, thrill visitors. Those seeking bigger thrills may visit the ball pythons and bearded dragons or get their picture taken with a lorikeet. Land-loving iguanas also lurch around in the mix.
