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?

No... the variable heat of tidepools is a really fantastic scientific question. Like several have mentioned, the sea will soon be back to these little pools, but... this is a significant source of stress for sure!

This is a really nice reply of clarification. This is exactly what I mean about the kind of "value-added" reply that adds to the conversation more than just a friendly sort of way. Thank you for this. This is the way it should be done.

Great job explaining the Ocean Zones! I think it is crazy how they just told the people to get off the island so they could blow it up. That was their home!? All it did was test a bomb and hurt the enviornment. Although Mr. Nash did talk about the...

It is crazy to me how we could eat at a lower trophic level and have 10 times as much food as we would have the next trophic level up. It doesn't make sense to me when everyone is eating at high trophic levels. Eating at lower trophic levels is he...

We can reflect on the night, or research about a topic and post here.

Wow. I really had no idea that so much of the food that I consume every day has algae in it. It’s kind of weird if you think about it. Well maybe it is only for me. In zoology, we have only ever talked about algae when we were discussing how it li...

Last monday nights class was very interesting. I was unaware of how the trophic levels affected us as humans. It is obvious to me that we need to get our resources and food from the lowest trophic level possible. I thought it was very interesting ...

Okay. I am totally confused. Are we supposed to reply to this? I thought we were supposed to research something that interested us like seaweed or something?

Seaweed is slimy and gross. I can't stand it touching my skin let alone putting it in my mouth! Apparently people eat seaweed. I know I have when eating sushi but never really thought anything about it. There are a lot of diet fads going around th...

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.
