My unit just finished learning about phylums in science class. There are about 35 major phylums into which biologists classify members of the animal kingdom. To reinforce what we had learned about phylums, the school planned a trip for us to the Adventure Aquarium in Camden, New Jersey so that we could see some of the animals we had read about. On Friday, May 7, 2010, we went on our field trip to the aquarium. I have visited the aquarium at least a dozen times. But each time I go I am still amazed at the views of the Ocean Realm. The Ocean Realm is this enormous tank. It has a huge collection of sea creatures freely swimming around in it. There are sharks, stingrays, shark rays and loggerhead sea turtles. There is a four hundred pound turtle named Bob that I always look for when I visit the aquarium. One strange thing about Bob is that Bob is a female turtle. Bob, a loggerhead turtle, is in the phylum Chordata. The sharks, stingrays and shark rays that share the Ocean Realm with Bob are also in the phylum Chordata. The Chordata is the animal phylum with which everyone is most familiar with because it includes humans and other
vertebrates. You can sit and watch this beautiful collection of marine animals gliding by, giving us a glimpse into their ocean world. I also enjoy walking through the shark tunnel. As you walk through the tunnels, sharks are swimming all around you. They seem so close. Sometimes I think I can reach out and touch them. But if you want to touch a real shark, you have to go to the Touch-A-Shark exhibit. In this exhibit, you can actually touch sharks, not the great white sharks or hammerhead sharks that you see in the shark tunnel, but smaller white-spotted bamboo sharks. All these sharks are in the phylum Chordata. Another fascinating area is the Jules Verne Gallery. As you walk through the gallery you will see several exhibits displaying all different kinds of sea creatures. I especially liked the giant octopus, jellyfish and the giant spider crabs. The giant octopus is in the phylum Mollusca, which are invertebrates with soft, un-segmented bodies that are often protected by a hard outer shell. The jellyfish is in the phylum Cnidaria, which use stinging cells to capture food and defend themselves. The giant spider crab is in the phylum Arthropoda,
invertebrates that have an
exoskeleton, a segmented body, and jointed
appendages. Irazu Falls is also a good place to stop by. There’s a waterfall and you can see some enormous fish from the Amazon swimming in the tank. If you like tropical fish, you should go to the area in the aquarium called the Caribbean Currents. There are hundreds of brightly colored tropical fish. If you look close enough, you’ll see some seahorses too. All these tropical fishes and the seahorses are in the phylum Chordata. Penguin Island is another great area to visit especially during feeding time. The penguins are in the phylum Chordata. These penguins are really smart. They know when it’s feeding time because they all gather at the door where the aquarium workers enter with food. It’s fun to see them swim and fight for food.
I really enjoyed our trip to the Adventure Aquarium. In my opinion, visiting the aquarium helped reinforce what we learned about phylums. Sure you can look at pictures and drawing, but seeing the real thing is much more interesting. I, like most students, learn best by seeing, touching and feeling objects that we have learned about in science class.
