The new St. Louis Aquarium is all kinds of... underwhelming. They marketed it as the next Georgia Aquarium, with massive tanks of whale sharks, manta rays, great hammerheads, beluga whales, penguins, deep-sea cephalopods, and more, and it has none of that. It’s really not worth the cost of admission, honestly, until it is significantly expanded. But it does have an excellent North American river otter exhibit, with plenty of underwater viewing. Definitely a step up from the St. Louis Zoo’s otter enclosure.
