The moon orbits Earth at an avaerage speed of 2,288 miles per hour (3,683 kilometres per hour). The Moon travels at different speeds during different parts of its orbit. It moves slowest when it is at furthest distance from Earth. The Moon moves fastest in its orbit when it is closest to Earth.
Some animals travel in shallower waters at times. These include larger fish, such as swordfish, chain catsharks and cuttlefish. Several types of eels, including wolf eels and snipe eels, can also be found in the mesopelagic zone. Some herbivores may venture into the mesopelagic zone at times, but do not stay there due to lack of food.
Eels like to hide in caves or holes but also need plenty of space to swim. Many species, especially the Spiny Eels, also enjoy burrowing into the substrate. Because most eels are naked or have very small scales protecting their bodies it is important that the substrate is soft, such as fine sand and peat.el-like Fish: Aquarium eels also include many so-called 'freshwater eels' that are not true eels. Yet they are all commonly called eels in the aquarium industry. Other Eel-type fishes include: 1  Swamp Eels. 2  The Swamp Eels are members of Synbranchiformes Order which contains 3 families.
