Many marine and freshwater bony fish achieve osmoregulation via

Different species regulate there body mechanism by going through different levels or frequencies of path ways for attaining the right balance of chemicals and water inside there bodies. For, the freshwater bony water fish there is lack for the optimum level of                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 certain materials and for that reason they have to look for some of the alternative options in order to fulfill these needs and requirements of the organisms.Most of the marine and the freshwater bony fish achieve the optimum level of nutrients and solutes with the help of ingestion the food materials or food resource which provide most of the water molecules required for there survival inside the region.

Ifound this on google “according to the findings, a foramen magnum positioned toward the base of the skull is found not only in humans, but in other habitually bipedal mammals as well.” i hope this you for what your looking for
