I thought last weeks discussion was very interesting. The thing that amazed me were the atolls and how they were formed. I realized that these atolls were old volcanoes that were islands, but the coral grew around the volcano, causing it to sink f...

Use the space below to reflect on our latest class session... and introduction to the ins & outs of coral reef formation. The slide set we used to facilitate our chat can be viewed here: (soon) In the space below, tell what connections you made ...

yes, and yes... and also simply trap it within a structure they can close. think: mollusks.

I understand now. That helps.

To an extent. Does this mean they find water to make gills efficient, or does it mean they produce a saliva or water based substance to clear up their needs?

Whoa. That's sick to think algae is in all those common everyday things Americans eat. Didn't he also say it was in gum. Or am I totally making that up? I'll have to check up on that.
on Monday
You did an awesome job looking up all those definitions. I'm a visual learner too, so when I was making my post. I opened up my Marine Biology book. I have to see it in person, or in pictures to understand something. One thing I think we all didn'...

Also, I have a quick question. In this picture, is this considered a tide pool? I am confused because it is not in an enclosed pool but it still has to go through the different levels of high-tide and low-tide.

So I love chocolate milk and pudding so this is a cool way to connect the ocean and the foods we eat to people like me who are not to much of sea food fans. I never would have guessed but i would have never really thought about it either.
on Monday
Hey this is what mine is about. There are the four different levels and that pretty much determines how much sun and water each are exposed to, i think.

I, being the procrastinator, am just starting to do this assignment (you know the one that is due in just a couple of hours). Therefore, I am doing this two weeks after the lesson and the thing that stuck with me the most was the tide pools. The p...

Before last class period I knew nothing about oceanic zones, I learned that there are two main oceanic zones called the pelagic and the Benthic zones both of which are seperated into smaller zones within them. I also learned that light penetrates ...
on Monday
Hmmmm..... I see it here just fine. Nicely done.
on Monday
What happened to my reply? When you click on Zones & Trophic levels and then go to the last page, you don't see mine at all, but if you go over to the Latest Activity and hit the "replied" link, you can see it.

During class, we began to talk about seaweed. When Mr. Nash asked if we knew what it felt like, I hadn't, because I'd never really seen seaweed in real life. I've been to an ocean and all, but never been to a spot that wasn't a beach where tons of...

Remember... the trophic pyramid is real. It is just that above coral reefs... it seems to be "inverted." Of course, this cannot be. There is simply no way to consume more than is produced. Thus, we spoke of the trophic pyramid on a coral reef as b...
on Monday
Again... excellent clarification of some possible confusion between supralittoral... and littoral.
on Monday
Apparent inverted trophic pyramid... apparent. It really cannot be inverted. In fact, this is related to the Law of Conservation of Mass/Energy.

Penguins and sea lions help produce new atlas

Recording hundreds of thousands of individual uplinks from satellite transmitters fitted on penguins, albatrosses, sea lions, and other marine animals, conservation scientists have released the first-ever atlas of the Patagonian Sea -- a globally important but poorly understood South American marine ecosystem.

Fish food fight: Fish don't eat trees after all, says new study

Recent theories suggesting that half of fishes' food comes from from land-based ecosystems may not hold water. Experiments show that algae, not land-based matter, is needed to build healthy and fertile aquatic organisms.

California's ancient kelp forest

The kelp forests off southern California are considered to be some of the most diverse and productive ecosystems on the planet, yet a new study indicates that today's kelp beds are less extensive and lush than those in the recent past.

Sponges recycle carbon to give life to coral reefs

Coral reefs live in some of the most nutrient deficient waters on the planet, so how do they survive? Marine biologists have discovered that certain sponges could be the key to reef survival. They recycle dissolved organic carbon that is unavailable to other reef residents.

Evolution of highly toxic box jellyfish unraveled

With thousands of stinging cells that can emit deadly venom from tentacles that can reach ten feet in length, the 50 or so species of box jellyfish have long been of interest to scientists and to the public. Yet little has been known about the evolution of this early branch in the animal tree of life. Researchers have now unraveled the evolutionary relationships among the various species of box jellyfish, thereby providing insight into the evolution of their toxicity.
