One species of salamander lacks lungs, so it breathes by absorbing oxygen through its skin and the roof of its mouth. The diving bell spider is able to breathe oxygen underwater by keeping air bubbles attached to its body with tiny, hydrophobic hairs.
Certain terrestrial animals, such as earthworms and amphibians, can breathe through their skins, but amphibians have simple lungs as well. All reptiles, mammals and birds breathe using lungs; in birds there is also a system of air sacs and air spaces within the bones that make breathing more efficient.
Respiratory System
Adult plethodontids (lungless salamanders) lack both lungs and gills, and rely on cutaneous respiration. Skin, in fact, is the primary respiratory surface in most amphibians and must be kept moist.
Fun fact: Crocodiles are NOT amphibians. They have lungs, no gills, and need to breathe air just like we do. So how do they stay under water for so long? Their bodies allocate and conserve oxygen very efficiently, enabling them to hold their breath for very long periods...
Abstract. Spiders (Araneae) are unique regarding their respiratory system: they are the only animal group that breathe simultaneously with lungs and tracheae. Looking at the physiology of respiration the existence of tracheae plays an important role in spiders with a well-developed tracheal system.
Ants do not breathe like we do. They take in oxygen through tiny holes all over the body called spiracles. They emit carbon dioxide through these same holes.
People, animals and insects also breathe a gas back out. This gas is called carbon dioxide. Apart from this, bugs don't breathe like humans and animals do. Bugs don't have lungs.
Sharks don't have lungs, but they do have to breathe oxygen to survive. Instead of breathing air, though, sharks get oxygen from the water that surrounds them. The concentration of oxygen in water is much lower than in air, so animals like sharks have developed ways to harvest as much oxygen as they can.
Yes, frogs have lungs like we do and if their lungs fill with water, they can drown just like us. Frogs can also breathe through their skin.
Reptiles are turtles, snakes, lizards, alligators and crocodiles. Unlike amphibians, reptiles breathe only through their lungs and have dry, scaly skin that prevents them from drying out.
In a study published Monday in the Proceedings of the National Academy of Sciences , researchers have now identified the first animal that doesn't use oxygen to breathe: Henneguya salminicola, an 8-millimeter white parasite that infects the flesh of Chinook salmon.
Bullfrogs… No rest for the Bullfrog. The bullfrog was chosen as an animal that doesn't sleep because when tested for responsiveness by being shocked, it had the same reaction whether awake or resting.
Jellyfish, also known as Scyphozoans, lack breathing and circulatory mechanisms. They do, however, require oxygen, just like any other mammal. Jellyfish have a number of physiological adaptations that enable them to absorb and retain oxygen, allowing them to survive in low-oxygen situations.
The porcine lungs have two lobes on the left side and four lobes on the right 2, 3, whereas humans have three right and two left lobes.
Unlike other fish with gills alone, lungfish can surface, take a breath and survive when other fish might be lacking air. In fact, much like many sea mammals, lungfish are obligate air breathers—they have to breathe air above water periodically to survive.
The world's largest lungs are those of the blue whale Balaeonoptera musculus. Its two lungs have a combined, total capacity of approximately 5,000 litres of air. Extremely efficient, its enormous lungs can transfer up to 90% of their inhaled air into the whale's bloodstream.
Various parts take part in the breathing process of an owl. Some of the parts involved include nostrils, trachea, lungs, heart, and blood capillaries. Air enters the respiratory system through the nostrils and is transported into the lungs through the trachea.
Grasshoppers don't have lungs like we do, but instead take in oxygen and give off carbon dioxide through air-filled tubes running throughout their body.
In cockroach, respiration occurs through spiracles – a small opening on the sides of its body. When air through external openings, enters into its respiratory system, spiracles serve as muscular valves paving way to the internal respiratory system. The respiratory organ of cockroach is referred to as tracheae.
Built for hopping, a kangaroo can hop for hours at a time. Its lungs use less oxygen than four-legged (quadrupedal) mammals moving at the same speed.
Like every mammal, dolphins are warm blooded. Unlike fish, who breathe through gills, dolphins breathe air using lungs. Dolphins must make frequent trips to the surface of the water to catch a breath.
Because they are aquatic species, squids breathe through the use of gills instead of lungs.
Scholars have long recognised that the survival value of pain means many animals experience it, supposedly with the exception of insects. But we surveyed more than 300 scientific studies and found evidence that at least some insects feel pain.
There are several ways for flies to transmit their larvae to people. Some flies deposit their eggs on or near a wound or sore, the larvae that hatch burrow into the skin. Certain species' larvae will move deeper in the body and cause severe damage.
Flies are capable of sophisticated behaviors, including navigating diverse landscapes, tussling with rivals and serenading potential mates. And their speck-size brains are tremendously complex, containing some 100,000 neurons and tens of millions of connections, or synapses, between them.
