The price you are able to negotiate varies depending on the time of year. Believe it or not, buying during certain parts of the month can get you a better deal. It can even depend on the launch date of a new model year. Read our tips on the best time to buy a car.
fish do not shed their scales when they grow as boss man says.. one thing I learned is when a fish loses its scales or a scale...the fish will not grow at all until the scale/scales are fully replaced or repaired ...this is because all of the fishes energy and nutrition go into regrowing the missing scales.ne thing I learned is when a fish loses its scales or a scale...the fish will not grow at all until the scale/scales are fully replaced or repaired ...this is because all of the fishes energy and nutrition go into regrowing the missing scales.
Bony fishes can swim forward and backward.   Gills:   Both cartilaginous and bony fish have gill slits but the bony fish also have gill covers (an operculum).   Reproduction:   In the Chondrichthyes the males have claspers which assist in copulation. Fertilisation is internal-almost unique among fish. Scales:   Cartilaginous fish have large scales called placoid scales. These have a bone like base embedded in the skin and a backward projecting enamel covered dentine spine. The whole thing has a central pulp cavity (rather like the structure of teeth). The epidermis and dermis form placoid scales.
