Course Objective

This course aims to introduce the fishes living in the deep seas with extreme environmental conditions. The course will cover the characteristics of deep-sea environments and the special adaptations of deep-sea fishes to the extreme conditions in their habitat. In particular, morphological, anatomical and physiological adaptations will be explained in detail. In addition, the impact of human activities in the deep seas will also be discussed.

Learning Outcomes of the Course Unit

1   to understand the extreme environmental conditions at deep seas
2   to understand the special adaptations of deep-sea fishes to the extreme environmental conditions
3   to identify the deep-sea fish species
4   to understand the ecological roles of fishes in the deep-sea ecosystem
5   to understand the threats on the deep-sea fishes
6   to find out that what should be done for the protection of deep-sea fishes
