Structural Adaptations

Some aquatic insects, such as the young of mosquitoes, breathe in oxygen from the air. Those insects breathe through air tubes which extend from their bodies and stick out above the water. Many aquatic insects cannot take in dissolved oxygen. They have to take in oxygen from the air.

Structural Adaptations

Seals are mammals but they are different from the other mammals as Seals have nostrils at the top of their snouts .They push their nostrils above the water surface to breath, however other mammals breathe in oxygen from the air only through their lungs. Seals can store enough oxygen to hold their breath for up to an hour.

Structural Adaptations

The blowhole of a sperm whale, a toothed whale, is located left of center on the frontal area of the snout, of which is actually its left nostril, while the right nostril lacks an opening to the surface although its nasal passage is otherwise well developed.

Structural Adaptations

Aquatic animals like fish, shrimp and tadpoles have gills in order to remove oxygen from the water, gills are feathery organs full of blood vessels. They rely on this special organ (gills) as water passes over the gills, dissolved oxygen is taken in and carbon dioxide is given out.

Structural Adaptations

Animals, such as salamanders, can stay underwater for long period of time as it uses it's skin to take in oxygen underwater that is why it's skin must be moist like how frogs and toads breathe and take in moisture through their skin through a process called cutaneous gas exchange, but they also have lungs with which they breathe. During the time they stay submerged under or buried in soil (such as during hibernation) they ONLY breathe through their skin.

Structural Adaptations

Aquatic insects, such as Water Beetles and Water Spiders, have body parts that are adapted to trap air bubbles. This is one way for animals to breath under water. These insects can extend their air tubes from their bodies and stick out above the water's surface. Aquatic insects like these cannot take in dissolved oxygen. They have to take in oxygen from the air. They have air tubes or breathing tubes that extend from their bodies and stick out above the water surface.
