Question

Give any two examples of aquatic animals respire using atmospheric oxygen​

Answer 1

Answer:

whales, dolphins are the examples

Answer 2

Two important examples of aquatic animals that respire using atmospheric oxygen are amphibians such as frogs, and mammals such as a whale.

• Frogs are creatures that live their lives partly on land and partly in the water. They have a developed respiratory system with lungs to enable them to breathe in atmospheric air. The skin of a from is also an organ of respiration as it enables the animal to absorb oxygen from the water while it swims underwater
• Whales are aquatic mammals with a very well-developed system for respiration. They are capable of holding their breath for an immensely long period of time. As they reach the surface of the water, their blowhole opens to take oxygen from the air in. This hole closes again as the mammal dives into the sea
• A whale is capable of regulating their heart rate to conserve oxygen and stay underwater for longer periods
