Open Ocean

 
 
The vast open ocean and deep sea are home to delicate jellyfish, light-producing animals, and other organisms ranging from the beautiful to the bizarre.
  • Be sure to stop by the Sea Jelly Lab and see what's growing in this open husbandry lab. Students, volunteers and staff are often seen working on a variety of projects here. You might even be shown baby jellies on the microscope monitor.

  • Shapes, colors, and behavior of the fish in the Fish Diversity Tank reflect where and how these fish live.  See how sharks come in an amazing variety of sizes, shapes, and habitats and how some of the biggest sharks are gentle filter-feeders instead of ferocious predators.

  • The Channel Islands are major breeding grounds for many thousands of seabirds, seals and sea lions.  Feeding and nesting habitats are displayed.

  • Whales and dolphins, descended from land mammals, are the largest and most intelligent animals of the ocean.  The lives of these big mammals are examined in special exhibits on feeding, a video of various cetaceans, displays of whale and dolphin skeletons, and recordings of whale sounds.
