The given diagrams illustrate the life process of saimon, which is a kind of huge fish.
Overall, it is evident that the saimon undergoes three physical stages as it grows to maturity, each of which occurs in distinct aquatic locations.
Firstly, the life cycle of saimon starts from eggs laying under small tones and reed in upper river, where is slow moving. After approximate 5 to 6 months, in each egg, an embryo develops gradually for the fry, which is 3 to 8 cm in length, to hatch. Then, the fry survives in lower river, which is fast flowing, to grow into the smolt, which is 12 to 15 cm in length during 4 years.
The following stage, occurs 5 years later, the smolt migrates to the open sea and develops to the adult saimon. The fully shape of saimon is 70 to 76 cm. The last stage, the saimon swims back to the birthplace to lay eggs, and the life cycle therefore starts anew.
