| We are the two who studied the marine worms, which are invertebrates. There are four groups of marine worms: flatworms, acorn worms, bristle worms, and ribbon worms. We mainly focused on flatworms and bristle worms because they are the most common. Most worms of any group are found on or under rocks, in coral, or sitting on the sand or buried under it. Flatworms are scavengers that eat dead animals or debris that floats around such as waste products from larger sea creatures. Bristle worms also eat dead animals. The stinging worms like the fireworms can sting and paralyze fish, snails, slugs, and other animals. Tube worms filter feed, eating waste or debris that falls onto their tentacles. Worms are asexual. Some flatworms reproduce by fission, which is dividing into two. Other flatworms can reproduce by stabbing each other with a stylet and inserting sperm into the wound. The injured one then becomes the carrier of the eggs. Some bristle worms are hermaphroditic and do not mate to reproduce. We went to Diamond Head, Sandy Beach, Coconut Island, Ewa Beach, and Kahana Bay. At Sandy Beach we found a milky-white worm about six inches in length, which then split into three different parts a day after it was put in captivity. We had a hard time finding worms because they are small and can camouflage with their environment. We managed to find a Pericelis hymanae at Sandy Beach and Kahana Bay, Ptychodera flava at Diamond Head, Ewa Beach, and Kahana Bay, and Paralanocera oligoglena at Ewa Beach and Diamond Head. We also found about seven other species.
Welcome to our worm page. Worms are the most beautiful and interesting species in the intertidal. They have a broad range of ways to eat food. One way they eat is filer feding, and some use sharp teeth. They are very essential to the intertidal food web. Worms like to eat practically everything like worms (yes, they eat other worms), fishes, birds, echinoderms, the list would be long, so lets just say almost everything eats them. There are two main types of worms in the intertidal. Bristle worms- another name for them is segmented worms- and flatworms. Some worms can be really harmful to a person’s health. The worm that you really have to look out for are bristle worms. You can touch them, and their bristles are going to really irritate your skin. The other types of things you have to look out for are the brightly colored flatworms. When they are brightly colored, it normally means that they are toxic. But they are poisonous normally if eaten, so don’t eat them. Worms can be found from the bottom of the ocean to t he shallow intertidal areas. Because they are in so many different areas, you would expect them to be found very easily, but it is not as easy as you think. Since they have many predators, they have as many good places to call home. If you are in the intertidal, you are going to find more worms if you look under rocks and in little crevices. If you took the time to read this, good for you because you have just learned something new, if you didn’t already know these things.
