You may think that since sharks have noses, they use them for breathing. However, unlike mammals, they use them only to smell ...

For instance, a new nozzle design, inspired by shark gill structures, was shown to improve mixing and reduce the vibration amplitudes in rod bundle assemblies, thus enhancing operational safety in ...

Fish gills are remarkable structures that maximize oxygen extraction efficiency. Typically located on either side of the pharynx, most bony fish possess four gill arches on each side, though this ...

Recently, the first two in a series of planned comprehension experiments were performed to measure the effect of the control structure diagram (CSD) on program comprehensibility. Upper- and ...

13. Gill Structure and Breathing Mechanisms Hellbender Salamander. Mynd í gegnum Unsplash Axolotls possess distinctive feathery external gills that protrude from the back of their heads, resembling ...

Behaviors such as vigorous twisting and turning further demonstrate an intense aversion reaction. Without water, the delicate gill structures that exchange oxygen for carbon dioxide stick together, ...

This work aimed to study the effect of new neonicotinoid thiamethoxam on the histological structure of common carp (Cyprinus carpio, L.) gills. Three experimental groups of fish were treated with 6.6, ...

Gills of the seawater fish Cathorops spixii (Agassiz, 1829) were submitted to routine processing for observation in scanning and transmission electron microscopy. The wrinkled surface of the gill ...
