This model demonstrates the important internal organs of the fish, such as the respiratory system, the circulatory system and the basic physiological structure of the fish. The complete visualization of some iconic anatomical structures of the fish anatomy, which shows in detail important internal organ systems of the fish, is a rare product in the teaching of aquaculture. The model is made of high quality ecological PVC, which is durability, so it is not fragile and hand painted. Adult fish specimens are an anatomical reference, exquisite manufacturing, and can be divided into three parts.Aquatic anatomy is an important part of animal anatomy. Very suitable for school teaching, learning, research exposure and can also be used as an important complement to laboratory decorations.
