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.
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.
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 ...
Hmmmm..... I see it here just fine.
Nicely done.
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...
Again... excellent clarification of some possible confusion between supralittoral... and littoral.
Apparent inverted trophic pyramid... apparent. It really cannot be inverted. In fact, this is related to the Law of Conservation of Mass/Energy.
Lungs are good at extracting oxygen from dry air. Gills are efficient only when wet.
Therefore, the paradox is most easily solved with regard to marine critters by finding a way to keep their gills wet during periods of drying.
Make sense?

Climate modeling may have missed something: Aquatic creatures mix ocean water by swimming
Understanding mixing in the ocean is of fundamental importance to modeling climate change or predicting the effects of an El Niño on our weather. Modern ocean models primarily incorporate the effects of winds and tides. However, they do not generally take into account the mixing generated by swimming animals.Sea stars bulk up to beat the heat
A new study finds that a species of sea star stays cool using a strategy never before seen in the animal kingdom. The sea stars soak up cold sea water into their bodies during high tide as buffer against potentially damaging temperatures brought about by direct sunlight at low tide.Deep-sea world beyond sunlight: Explorers census 17,650 ocean species on edge of black abyss
Scientists have inventoried an astonishing abundance, diversity and distribution of deep sea species that have never known sunlight -- creatures that somehow manage a living in a frigid black world down to 5000 meters (three miles) below the ocean waves.Paleontologists find extinction rates higher in open-ocean settings during mass extinctions
Researchers have uncovered a strikingly pattern for ancient mass extinctions: extinctions rates during mass extinctions were significantly higher in open-ocean-facing settings than in epicontinental seas, indicating that open-ocean settings were more susceptible to the mass-extinction-causing agents.Is 80-year-old mistake leading to first species to be fished to extinction?
A species of common skate is to become the first marine fish species to be driven to extinction by commercial fishing, due to an error of species classification 80 years ago.© 2009 Created by Sean Nash
