PURPOSE: An animal transfer passage for a waterway is provided to enable reptiles, mammals, and wide animals to escape from a waterway without replacing an existing waterway. CONSTITUTION: An animal transfer passage for a waterway comprises a fixed passage member(10) and a variable passage member(20). The fixed passage member is hung on an upper opening of a waterway. The variable passage member is rotatably coupled to the fixed passage member, and connects the bottom of the water way with the fixed passage member. The angle between the variable passage member and the fixed passage member is changed depending on the amount of water flowing in the waterway. |
