Today my group and I went to our Eco place at Hanuma Bay. Our area that we chose is on the left side of the bay because we were told by one of the marine biologist that works there that the left side is more active with wildlife. When we were observing our area we noticed that there was some white sand and there where also some green sand that is native to this island. We also saw that there where a lot of reefs and coral in the ocean where we where observing. There where also some native plants there such as the Naupaka plant and the Lauwiliwili tree which has leaves that look like the fish called the long nose butterfly fish. There where also surrounding cliffs around where we where. Today at the bay the current was a little rough. I think that this is a good place to study because it has Aquatic and land animals and it also has a variety of plants there. I think that my group and I will be able to learn alot more about Hanuma bay in our upcoming visits. I am really excited because I want to learn more about the aquatic animals in the bay. Even though we could see a variety of animals from the surface I am interested in getting a closer look at the aquatic animals in our Eco place. I also think it is a good place for my group to study because there where also a lot of plant life for us to study there. I think we will be able to get a lot of information because I think there are alot resources that we can use to help us get as much information as we can about our Eco place. My group and I saw a variety of niches when we where at our Eco place. I think that my group and I have made a great dissision to do our science project at Hanuma Bay because of the things that i have mentioned above. The GPS coordinates of Hanuma Bay are Latitude which are 21degrees 16'11.57"N. The longitude 157 degrees 41'39"w. The Rip-o-meters test results Pohinahina:33,30pennies length 2 1/4 in. Naupaka:20,25pennies length 6 in.Lauwiliwili:16,23length 7.5in. //**Assigned Journal #1**// There was a variety of aquatic and land life there at Hanuma Bay. Some of the things that we saw where the Everman's Coral,Zebra Lenny,Orange Spine Unicorn fish,and the Hawaiian Muscle. The Everman's coral is one of the biggest pieces of coral at Hanuma Bay. It is located not that far off sure on the left side of the bay. Since the water/current comes through the left side I think that the coral has sufficent food supplie. I think it has a suffcient food supplie because the current probably pushes the plankton that it eats into the bay and the coral is able to feed. Coral can also get or make its food from the sunlight that it gets. So I think it is doing well in the niche that it is in. Another one of the animals I am going to talk about is the Hawaiian Muscle. The Hawaiian Muscle is usually found in green algae or Bryopsis. The muscle's niche is a good one because it shelter in the algae and it also can get food from the water that continuelously flows through the muscle's niche. Next, is the Zeba Lenny and this fish lives in the tidepools and is able to jump. The Zebra Lenny is able to see the next tidepool that it wants to jump in to escape a predator. This fish is able to escape many predators because it niche gives it many places for it to hide from danger. The last fish I will be talking about is the Orange Spine Unicornfish. This fish dosn't really have a horn but it does have two spines. You can tell if this fish's gender by looking if it has any filaments on it. If it has filaments that means the fish is a male and if it dosn't it is a female. Although this fish has no horns it is in the unicorn fish family because of its spines. This fish usually is found near the various reefs at Hanuma Bay. It's niche allows it to have shelter and to have enough food for it to surrvive. So as you can see there are a variety of niches that are located in my eco area or the place that I am studying.

//**Free Journal #2:**// My group and I decided that I would focus my study on the aquatic animals that live within the bay. I started my studies when my group and all went down to Hanuma Bay. We first went and made some more land observations then we went into the water to look at the waters enviroment that the fish and other aquatic animals live in. When we were in the water we saw a variety of wildlife. For example we saw: Parrot fish,Convict Tang, Owama or (goatfish),Omilu,Barracuda,and other variety of ocean wildlife. I observed these wildlife in their natural habitat which is known as the ocean. The first fish I will explain is the Convict Tang. This fish is an organism that lives near the reefs and feeds off the variety of algae that lives there. This fish also gets a shelter and protection from the reef in which it lives. This fish also may also have some camouflage from the stripes that go down the side of its body horizontally. The next fish I will talk about is Owama this is ocean floor dwelling fish. It has a mouth that is specialized for eating food off the groundand it also has whisker like structures that are used to look for food and to sense things. Its color also helps it to camouflage when it is swimming along the sand in its own enviroment. The next fish that I will be explaining is the Parrot fish. This is a fish that spends most of its time eating the reef and making sand. This fish also usually found by the reef because it provides food,and shelter for it. The Parrot fish uses its strong teeth to crush the reef to make it into sand. You can tell when you are looking at a parrot fish because the scale of a Parrot fish are usually colorful like the rainbow. The last fish that I will explain is the dangerous Barracuda. This fish usually is found near the reef also because it is quietly waiting for an unexpecting fish to swim by. When the Fish swims by it is able to strike with lightning fast speed and is able to kill its prey with its sharp teeth. This fish is a hunter that waits patientenently for the right time to strike its unsuspecting prey. Why is there more fish on the left side then on the right side? Why is preserving Hanuma Bay so important to the natives?

//**Assigned Journal #2:**// The fish in the Eco place come in many different sizes,shapes,and colors. The fish that I am going to concentrate on are the Parrot fish,Owama,and the Barracuda. These different species are the same but they can also appear differently. These species of fish have different characteristics that make them better than some of the other fish that do the same things that they do. I will now start to talk about the Parrot fish. There are two different types of this fish. You can find this fish with rainbow scales and you can find the same species of fish and it can have red and white scales. I think the fish with the red and white scales is more fit for survival than the fish with the colorful scales. I think that it is more fit for survival because of its darker colored scales this could make it less likely to be eaten by a predator. It can hide and blend in all the dark places because of its scale colors. The colorful Parrot fish I think is more exposed to gettting attacked by a predator because you would be able to see its colorful scales more than the other fish's scales. I think that the Parrot fish with the darker scales will have a better chance in reproducing to pass on it traits to its offspring. The next species of fish that i will explain is the Owama. This fish lives on the ocean floor. These fish get bigger as they mature and turn into Veke. I think that the veke will have a better chance in surviving because it is bigger than the Owama and it is more mature. Since it is more mature it might have a better chance to survive because it has lived so long already. I think the only the Owama who survive to become veke will be able to pass on their successful traits onto their offspring. The last fish that I will explain is the Barracuda. This fish is a very aggresive fish and it also has very sharp teeth that it uses to kill its prey. I think that only the barracuda that are able to efficiently hunt its prey and is able to survive to adult hood will be successful. These lucky few will be able to reproduce and keep its going. It could also become more effecient hunters and might evolve new structures to make it better in hunting its prey. Second Rip-o-meter test results. Pohinahina:13,22 Length 1 3/4in. Naupaka:17,16 length 2 1/4in. Lauwiliwili 40 .plus,18 pennies length 4in.

On November 16th, I went to our Eco-system again and continued my observations. This time was a little different than the other times I had gone with my group because this time I went at around 8:15AM. When I got there I saw that the A'ama crabs were out on the rocks in a big colony. They quickly went back to their usual hiding spots under a nearby boulder. I noticed that the tide was pretty high when I got there; then a little over fifteen minutes later it got noticeably slower. I also went to the other side of the bay and saw that the trees were wind-swept up toward the mountains. When I went into the water I went towards the right on the left** **side of the bay. I looked at the right part and the left part of the of the left side. On that particular side, I saw that the fish were very healthy and very big in size. When I went to the left part of the left side I saw that the fish were noticeably small****er as compared to the fish on the right side. The water on the left side was also a little shallower than the right side of the left part of the bay. An inference that I made of this situation is that since the water was deeper it allowed for the fish to grow bigger because there was more food and enough room to sustain them. I also saw that the waves that were coming in were getting by the natural wave breaker also known as the reef. The waves were gradually slowed down as the waves went across the reef. I think there are more fish on the left side than on the right side because I noticed more reef structure in the pictures of the bay at the information center. I also think the left side has more activity because the current or the new water from the ocean comes in from the left which makes the water cleaner and a better place to live. The water in the bay is continuously replenished with the "new water" the current brings in from the ocean. While I was there I also noticed that the sand on the left side was coarse. As I walked to the right side the sand got coarser until I reached the end of the bay. At the end I noticed that the sand was soft because it was the original olive green sand. The deeper the water gets the bigger the fish will become because there will be more room for them to grow and sustain themselves. I also think the activity has to do with the water coming in from he left** **side because I think since the water is always fresh that more fish live on the left side. There actually is a lot of reef structure on the left side more than the right side of the bay. I think since the reef provides a variety of food sources** **which allows a variety of speices to live in the bay. I think since there is more runoff on the right side of the bay it makes the water more dirty. This is probably another reason why the left side is more active with fish and wildlife.** If there is more reef structure then there will be more activity. to test this see how much reef there is on a scale and how much wildlife on a scale.

When we visited our eco-place for the fourth time we continued to take detailed observations. We saw that the fish were hanging more on the left side of the bay then the right side. When we posed the question how come there is more fish on the left side then on the right side to one of the faculty members. They said,"that you only think there is more fish on the left side because there are more places where you can see them. Where as the right side of the bay is made mostly up of reef so there is fewer places where you can actually see the fish. Which means that the right side is at a disadvantage because there are less open areas to see the fish. So people automatically assume that there are more fish on the left side because they can see more of the fish then when they go on the right side. When we took a look at a picture of the bay we could see that the right side did indeed have more reef then the left side and we also noticed that the left side had more open spaces. So my experiment was to make a scale of how much reef I saw and of how much marine life that I saw. So what I did was I went on the left side of the bay and looked at how much reef that I saw and how much marine life I saw. I also did this for the right side of the bay as well. On the left side I did notice more fish and less reef. When I went to the right side I noticed that there was more reef but less fish. As a scientist you can never fully answer and understand a question because sometimes questions are supposed to remain unsolved. My group and I still tried our best to figure out why things happened in our Eco- place the way that they did. After looking at what I saw I concluded that the right side has more fish because it has more food for the marine to live off of. Since there is so much reef in that area you can never know for sure if the right side has more fish then the left side because the reef block you from seeing all of the fish. The right side is at a disadvantage and people just see the fish on the left side because of all the open spaces. I used this scale to compare the right and left side of the bay. The left side got a 5 on marine life and a 3 on how much reef life. the right side of the bay got a 5 for the amount of reef life but a 3 for marine life.
