Transcription

1 Attach ticket stub here Name Due Date: Long Beach Aquarium of the Pacific Date BC students go as a group: Cost w/bc group: If you attend on your own: $25.95; ages 3-11 yrs $ (Prices subject to change.) Parking is usually $8, but may be more, depending on date. Check ahead online at You may purchase Aquarium/L.A.Zoo combo tickets online for $36 for adults and $25 for children. But do not try to go to both places on the same day. Save your aquarium ticket stub and attach to this worksheet. If you go with the Biology dept field trip, stamp your worksheet at one of the marine life stamp machines around the aquarium. Directions from Bakersfield College are attached (back page). **If you are attending with the BC Biology Dept group, you will enter through a side gate. Go inside Great hall and start at the main aquarium entrance. You may move at your own pace through the aquarium. Pick up a Visitor s Guide w/a map at the information desk by the front door. Then try to follow the general pathway described below, starting from the front entrance. Take a break to eat lunch or sit and enjoy a particularly beautiful exhibit. Refer to the APPENDIX at the back of this worksheet for the phylum and class names and characteristics. Changing Exhibit Gallery (across from Visitor Information desk near main entrance; not the Tropical Pacific Preview) This exhibit changes on a regular basis. 1. What is the topic of this gallery today? 2. Find three important aspects of this exhibit and explain them. 1

2 2. (Continued) -- Great Hall of the Pacific Exhibits Tropical Pacific Preview 3. What are Pacific Island nations doing to help conserve the coral? Blue Whale Look up at the life sized model of a Blue Whale. Characteristics: ft long (as long as a Boeing 737) Weighing between tons (160, ,000 pounds) Population: The Blue whale (Balaenopteridae) is endangered with a worldwide population of between 6 and 14,000. It was hunted nearly to extinction by the whaling industry. They have been seen regularly in the Santa Barbara channel in the last few years providing hope that they may be increasing in numbers. Identification: Mottled blue color, small dorsal fin found approximately 3/4 along the back from the head. 2

3 Behavior: The Blue Whale is a baleen (toothless) whale sieving tiny organisms from the water, collecting them with its tongue and swallowing them. Dives may be as deep as 490 feet. Incredible blow (spout) of 30 feet appears as a slender column. Protection: In 1966 international law placed the blue whale on the protected list. You may look at the information on the second floor overlooking the model now or later for this information. 4. What do blue whales eat and how do they eat it? Blue Cavern The Blue Cavern at the end of the hall represents a famous diving location on Catalina. Using the signs, identify as many different species as you can. 5. Which species appears to be the largest? 6. Name the different classes of vertebrates that are present (use appendix). 7. Why is the giant sea bass a success story? Southern California/Baja Gallery Go to the right into the Kelp Forest. Follow the exhibit around. You should be able to identify the Kingdom and Phylum of all of the invertebrates in these displays. 8. Fill in the chart below as you move through this gallery (use appendix if necessary). Phylum Cnidaria Molluska Arthropoda Echinodermata Organism Common Name Scientific Name 3

4 9. What interactions do you see between kelp and other organisms of the amber forest communities? Don't miss the shark egg case and the mantis shrimp displays! 10. Where on the sea floor do crabs and lobsters take cover? 11. What are pinnacles? 12. Name two marine animals whose population numbers are dwindling due to overconsumption by humans. Walk through the underwater viewing of the Seals and Sea Lions and exit to the outside exhibits. Shark Lagoon Stop here and touch a ray or shark. 13. What animal did you touch and what did the skin feel like? Observe the sharks through the underwater viewing window. Lorikeets Spend a few minutes with the Lorikeets. No need to feed them just watch their behavior. 14. What is the main food source for these beautiful birds? Our Watersheds Observe the exhibit of Los Angeles area watersheds. 15. Where does the rainwater go? 16. Is current water usage in Southern California sustainable? Why or why not? 4

5 Surf, Seals and Sea Lions Go up the stairs and observe the seals and sea lions. Stay for a show, if your timing is right. 17. To what Phylum do Sea Lions and Seals belong? Class? (Use appendix.) 18. On what California Island do 4 species of sea lions and seals breed? June Keyes Penguin Habitat A World of Penguins (touch display) 19. In what hemisphere are penguins found? 20. Name 2 different penguin species and explain what they eat and what their nest is like. Southern California/Baja Gallery Enter the upstairs exhibit door and observe the various displays. 21. Just inside the door--where is the Sea of Cortes (Gulf of California)? Walk along the upper walkway and look at the changing pattern of California s water and climate. 22. What significant event happened during the Eocene Epoch ( MYA)? 15 MYA? 5

6 1.8MYA 11,500 years ago? Northern Pacific Gallery Now walk to the left and enter the Northern Pacific Gallery. Notice how the fish and seaweed move in the surge tanks. 23. How do the species living on the rocks survive in the wave-affected environment? Stop for a while at the diving bird display. These birds have some unique adaptations. Each species of bird on exhibit, while having similar lifestyles, have adapted with very unique niches. 24. Identify the birds in the exhibit. Which ones are present? 25. Read the display information on the wall to the right of the diving birds. How does the shape of a Murre egg help the species survive? Sea Jellies (opposite the Murre egg exhibit) Observe these beautiful drifters for awhile. Most jellies belong to the phylum Cnidaria (Comb jellies belong to phylum Ctenophora). 26. Look up phylum Cnidaria in the appendix at the back of this worksheet. What characteristics allow sea jellies to be classified in phylum Cnidaria? 27. What are their tentacles used for? 28. Circle any of the following necessary for movement: brain heart eyes 6

7 29. Are any of the above present in a jellyfish? Giant Pacific Octopus Walk forward to the corner octopus display. Observe the Giant Octopus. This animal is not advanced among the invertebrates and yet its eyes and behavior are very well developed. 30. Describe at least two adaptive characteristics that enable the octopus to be successful in its environment. Coastal Corner 31. Touch one invertebrate. What animal was it? What did it feel like? Sea Otter Habitat Observe the Sea Otters during an "enriched session" if possible (10:45AM, 2:15PM, 4:OOPM). 32. How do otters crack open their hard-shelled prey? 33. Why are otters a keystone species? 34. Sea otters were hunted almost to extinction for their lush fur. What challenges do they continue to face, even though currently protected from hunting? 35. What can you do to help protect sea otters? 7

8 Deep Waters the Twilight Zone Check out the Lion s Mane nudibranch. It uses its umbrella to trap prey. Look at the giant spider crabs, tanner crabs, and king crabs. 36. What phylum do these belong to? Now continue to the left to the incredible upstairs "Tropical Pacific" display. This is the final exhibit and it's fantastic! 37. Describe the coral lagoon. Tropical Pacific Gallery 38. What is the reef crest? Describe the environment on the reef crest. 39. Many coral have single-celled algae growing in their tissues. What is the importance of sunlight to these reef coral? 40. Why are coral reefs in trouble? 41. Describe the symbiotic relationship between the clownfish and the sea anemone. (Where s Nemo?) 8
