Empty the Tanks

"Empty the Tanks is not a radical movement demanding the release of all captive marine mammals into the wild. Some of these animals might be great candidates for release, but those that are not should be retired into sea pens, where they can enjoy the rest of their days in natural seawater, feeling the waves of the ocean around them. They should not be worked until their last breath is taken and then thrown out like trash and replaced." -Rachel Carbary

Zoo Blues


Presenting animals to zoo visitors as living exhibits teaches children that animals can be manipulated in order to fulfill our own curiosity about them. It suggests that animals have no right to be treated as individuals who think and feel for themselves. It fails to recognize that animals have their own needs to be met, for their own purposes.

Zoo Blues

Why capture and breed animals only to keep them captive and prevent them from exhibiting natural behaviors? There are many legitimate conservation agencies equipped to help dolphins thrive in the wild.

We are calling on the Indianapolis Zoo to follow the ethical lead of The National Aquarium.

“We also think it’s important that people learn about dolphins in the context of what they really do in the ocean and what kind of lives they lead.” – John Racanelli, CEO of the National Aquarium in an interview on NPR’s Weekend Edition.

Learn About Ocean Animals

  • Learn about Nova and other dolphins at the Indianapolis Zoo

  • When viewing captive animals, you will likely miss out on seeing a variety of their natural behaviors. Planet Earth is an amazing way to view animals in their natural habitat.

  • Information about Common Bottlenose Dolphins.

  • Although bottlenose dolphins are not one of the endangered dolphin species, they are the kind you generally see in aquariums. The Indianapolis Zoo breeds a non-endangered species with twice the calf mortality rate as dolphins in the wild.
