Adaptation of living organisms | Secondary One | Unit 1 - Chapter 1 - P: (3/8) | Integrated Sciences
In This Lesson : Biological adaptations Examples 1. Some deep ocean fish have special abilities to regulate respiration under the state of oxygen deficiency. A famous example is the Electric Eel, which lives at depths of thousands of meters, where oxygen levels are extremely low. These fish have developed very large gills, with very fine capillaries that maximize the efficiency of extracting the little oxygen found in water. In addition, they can slow down their metabolism to minimize their oxygen needs. 2. Deep-sea fish have strong and durable arteries and veins that can withstand the high pressure to adapt to the high-water pressure at great depths.
