Ocean Going

 Whales, which grow to such great sizes, do so because of the buoyancy of water.

A set of three models, each with a model of a person for size comparison, is here. The blue whale is the largest animal on the planet.

The colossal squid is the heaviest invertebrate on the planet.

And the whale shark, the largest fish around, is a gentle giant.

Panels look more at how swimmers in the ocean function. 

This display features a cutaway of a blue whale skeleton, to show how much blubber surrounds the skeleton.

Another angle on the actual skeleton of the blue whale.

The path leads into an area on freshwater life. A terrarium features a spotted turtle.
