    The schooling pattern [1] in marine ecology is a common migration pattern for fishes of different swimming styles, such as carangiform of makrells, sub-carangiform of salmonids or anguiliform of eels [2]. This pattern is not only to move for food or survival, but also to avoid the predators and save the body energy loss, such as diadromous fishes of eels or salmons. In this talk, a model of multiple annugiliform swimmers, such as lamprey [3], is created to simulate the schooling pattern. The adaptive mesh refinement immersed boundary method is used for the numerical solution for the simulations. Moreover, the factors of body [4], such as body stiffness, spacing or body waveform, for swimming in schooling pattern will be investigated.
