Live Sand Dollars. Most people probably don't realize that sand dollars are not those bone-colored shells that we are all used to seeing. They are a type of sea urchin that's fuzzy, and in the case of these, with a slight purple tint. They sit at all angles on the bottom of the ocean. What we normally see is the outer shell after the fuzz has died off and left nothing but the skeleton.
- No Fish No Future - does no one understand that overfishing has gone so far the fish we are catching are smaller and smaller because we've caught most all the larger and soon we will have nothing to catch meaning nothing in the ocean will have anything. There will be nothing left!
5 depth zones have been identified in the ocean. Life is most abundant in the uppermost ‘euphotic’ layer, where photosynthesis occurs. The mesopelagic is practically dark, and many creatures hide here during the day. The bathypelagic zone begins at 1,000 metres, where the pressure is nearly 100 times greater than at the surface. Below that lies the abyssopelagic zone,down to the sea floor-except where ocean trenches cut through the sea bed, creating what is called a hadopelagic…
The pistol shrimp is the NOISIEST creature in the ocean. Colonies of them make a distinct snapping noise that overshadows nearly all other sounds throughout the world's oceans, including the calls of some whales. In fact, they are so loud, their snapping sounds interfere with military and scientific sonar (so much so, that hostile submarines have used large colonies of pistol shrimps to hide!).
