          CRAYFISH AS A PET  2                                         As part two of crayfish as a pet, I am writing the rest of the crayfish facts.  Feeding a crayfish Feeding a crayfish is pretty much the same as feeding a fish. Just make sure that there is something that reaches the surface of the water so the crayfish can climb up this to reach its food. Try to put most of the food near this climbing source. The crayfish will also use its legs (and rarely, its PINCERS!) to pick up the food that is left out on the bottom. The crayfish can also be fed bits of meat and rotting leaves.   Moulting Once in a while, crayfish shed their shell. They might suddenly fade their colours, this might mean that they are getting ready to moult. They will lose interest in feeding and might just hide away. When this happens, don’t feed them as they w...

                             CRAYFISH AS A PET Crayfish is a freshwater lobster. They can be kept as pets, in a small or big aquarium made for fish. They are crustaceans with two sharp pincers and antennas. They are quite easy to keep. I have written a little bit on how to keep them (based entirely on my own experience)   making the crayfish's home A few cleaned rocks and a log will do well as substrate for a crayfish aquarium. In a smaller aquarium it is not needed, but something that the crayfish can climb up is needed, as an aerator will not be needed if climbing sources are there. But these will have to be kept firmly as the crayfish likes to change position of its furniture. Add some substrate for the crayfish to hide as well. Gravel or sand is not compulsory, but it will possibly make the aquarium look nicer. And also, as the crayfish ...

                    down to the oceans    This time am going to write about four more oceanic features. Continental shelf This a gently sloping area that borders a continent. It extends offshore from almost nothing to 1000 miles wide and about 180 meters deep. Continental slope This a very steep slope that drops down from the continental shelf. It could be 12 miles wide and 10000 feet deep. Abbysal plane   This is the most level surface of planet Earth. If sediment collects over the rough parts of the ocean floor we call it an abbysal plane. Mid ocean ridges these are continuous mountain chains that can be found in every big ocean. They represent more than 20 percent of Earth’s surface.   (photos are from internet) And with that, I complete DOWN TO THE OCEANS. please keep visiting my blog.  

Hydrothermal vents hydrothermal vents As part two of down to the oceans I am going to write about hydrothermal vents.   Hydrothermal vents are chimney like towers that were of course, made naturally. They lead deep into the earth’s surface. Heated chemicals boil up from these natural chimneys in very high temperatures. Strangely in the water that had turned cloudy blue, small bacteria-unseen to the naked eye, and also pale crabs, a type of sea worm and other types of animals lived.    life from hydrothermal vents (photos are from internet)
