We saw some amazing fish and other sea life at the aquarium in Boston. There were plenty of jellyfish, sharks, sting rays, turtles, penguins, seals, and more. The variety of fish there is incredible. They even have a mermaid’s purse where you can see a shark embryo grow and eventually hatch!!! The touch tank is another favorite where you can safely touch sting rays and sharks. We easily spent most of the day at this aquarium.
