Summary:
The oil spill has been effecting the sharks very dramatically. Reacher Niel Hammerschlag, who has been studing sharks for a decade now, is tagging sharks in the Gulf to see their migratory and behavioral patterns. Sharks are pretty much at the top of the food chain and they pretty much eat everything under them, if they never touch the oil something they might eat might of been hurt by the oil. This will make the sharks die because they won't be eating as much. The way that sharks breathe is they "take in the water, the water goes over their gills and they extract out the oxygen." So if the sharks are in the oil it will be extremely hard for them to breathe. In the Gulf there are spots where people are not allowed to fish, because we don't want the people to get sick. If we don't get this oil cleaned up soon who knows what will happen to all the sharks.
Opinion/Reflection:
I think that it is a horrible thing that happened in the Gulf. Also it is pretty cool to see how some people are taking things into their own hands, and making sure that we are doing everything that we can, to try and see if the sharks are being effected by the oil. Its very interesting to see that if one thing gets damaged in a food chain how the rest of it will be effected. I hope that we can have the oil cleaned up fast so the food chain will be able to go back to normal!
Questions:
1. What is the name of the guy who is tagging these sharks?
2. How long has he been studing sharks?
3. How do sharks breathe?
4. What do you think we can do to help these sharks?
That was an interesting article Lauren. These sharks are probab;y important to the ecosystem because they make sure no population explostion happens. If these sharks are in danger then who knows what other animals in that area are being hurt. I think that they're going to need all the help they can get down there.

3) They take in the water run it over their gills, and extract the oxygen
4) we can start a donation pr something because it's not likely we'll be able to actually go down there to physically help out.
Wow i never really thought about sharks dieng or anything from the oil spill. With out the sharks being alive other fish lower on the food chain could over populate. Without these sharks in the water the food chain is messed up and the fish can't keep each other in "check".
ReplyDeletethis ink talks more about shaks and the spill :

4.i think by really all pitching in and cleaning this spill can help them faster but what is done is done and we have to learn from our mistakes that have happened.
Before I read this I already knew about the creatures of the sea, and how they are affected by disruptions in their food chain. I do think it is important to realize that even if you don't like sharks, they are an important part of the ocean ecosystem. And when one part of the ecosystem suffers, so do other parts.

3)The sharks take in the water, the water passes pver their gills, where they extract out the oxygen from it.
4)We can educate others about why it needs to be a priority for scientists to find ways to remove the oil from the water to clean it. We can also try to educate others about this issue, so we can all fight to get better standards for oil rigs, so that nothing like this happens again.
This did not surprised me, because even sharks, which everyone believes to be "big, bad, and evil" can be hurt by simple oil, which should be branded, while sharks should be taken of that "tag." Sharks are very vital to our ecosystem, because without them, other fish would over-populate, the biodiversity ratio would lower, and a plethor of other unlikeable repremands would commence happening. And as Dylan said, "Wehn one part of the ecosystem suffers, so do other parts."

1)Niel Hammerschlag
2)About a decade
3) the gills "inhale" water, and as it passes over them, oxygen is extracted.
4)One way we could help them is by temporarily put them in tanks, to be able to clean them. This could be possible if they are flipped over, therfore going into a catatonic state, unaable to move, so that trained people could clean the oil off of them.
