Water Planet

The Water Planet exhibit's blue glow creates a beautiful place for exploring watery adaptations.
Explore the dramatic connections between water and life in a luminous gallery of jellies, pythons, pipefish, seahorses, lumpsuckers, and other remarkably adapted animals.

Water Planet features an ever-changing cast of fish, reptiles, amphibians, insects, and more—all organized by adaptations to water. Seven clusters of tanks highlight animals that have evolved fascinating methods of feeding, movement, reproduction, defense, sensing their surroundings, surviving in deserts, and living both in and out of water.

Going to extremes
