Cabrillo Aquarium Exercise: The Invertebrates Directions to the Cabrillo Marine Aquarium, San Pedro: From PIERCE take the San Diego Freeway south to the Harbor (110) Freeway - San Pedro. Continue on the Harbor Freeway south, take the Catalina exit/Harbor Blvd (towards Vincent Thomas Bridge). Turn right at the end of the offramp and take Harbor Blvd. all the way to 22nd St. Turn right on 22nd and then left on Pacific Ave (second traffic light). Take Pacific Ave with Fort Mac Arthur on your left to 36th street. Turn left onto Stephen White Drive and follow curve to right to Cabrillo Beach. There is limited free parking along and pay parking at the aquarium. Weekdays during the winter parking is (was?) free. The aquarium is closed on Mondays. The number is 310/548-7562. What to do before going. Read over this exercise and look up each group of organisms in your text. By first reading and studying the organisms you will better benefit from the aquarium visit and be able to complete the exercise more quickly. What to do once you are there: On arrival obtain a Visitor = s Guide from the information desk. This has a map and a listing of the major exhibits. In the exercise that follows I reference the exhibit by its name in bold italics to make it easier for you to locate the information. This is a very comprehensive hand-out. Use it you your best advantage and don’t worry about completing every detail. It will review almost everything we have covered in class about marine invertebrates and fishes. You may not finish it in one visit – get what you can out of it. After you have looked over the exercises you should be able to figure out where you are weak and what to concentrate on. If some of the exhibits have changed – just go on to the others. For each of the groups you need to read over the material in this exercise while you are looking at them, and then fill in some species you observed where it says “examples”. For each of the organisms look at the exhibits indicated and list the genus of the organisms that belong to the group described after A examples: @ . Breakfast/Lunch/Dinner. I recommend the Lighthouse Deli on the corner of Pacific Ave. and 39th St. Just 3 blocks toward the water past Stephen White Drive. 1

Sponges (Phylum Porifera) The body is covered with a perforated A skin @ (epidermis) and body penetrated by numerous small channels forming the body cavity (spongocoel). Channels lined with flagellated A collar @ (choanocyte) cells. Feeding is accomplished by creating a current with flagellae (microscopic A whips @ ) of collar cells that draws water in through skin and through channels where food is trapped by the collar cells. The prey is primarily phytoplankton, bacteria and detritus. Sponges are found mostly in dark areas: beneath rocks, and in caves due to poor ability to compete with faster growing alage for space. Exception is in the tropics where the grazing pressure from fishes on algae allows the less palatable sponges to persist in lighted areas. Animals That Look Like Plants, Filter Feeders
