I would argue that the Albatross is one of the most efficient animals. It does not have to flap it's wings when it soars across the oceans since it's wing bones lock into place. It is also able to sleep while flying. It has a glide efficiency of 20 feet forward for every 1 foot down.
Gaseous exchange surfaces inside the body of terrestrial animals help to protect the delicate respiratory membranes from drying out and damage. This internal arrangement also helps to regulate gas exchange and maintain proper moisture levels, especially in dry environments. Additionally, it provides a more controlled and efficient system for exchanging gases such as oxygen and carbon dioxide with the bloodstream.
its the balance of the system... ecologically most herbivorous animals have this innate tendency to be in groups to protect themselves and most carnivorous animals have a tendency to be singular or to detach themselves from other members of the same group other than mating rituals. its a delicate balance evolved from the ages. if the big cats have this capacity to be in groups no animals will survive this massive strength, so evolution has played its own cards in making this positive by making the carnivorous animals powerful and singular entities and the weaker sections to be in massive heard to protect themselves by their numbers against the powerful animals.
There are many animals that display solitary behavior due to negative human interactions. However, there are some animals that are solitary by nature. These animals include the Giant Panda, the Ringed Seal, rhinos, the wombat, cougars, and tigers.
The closest spies of dog to a wolf is the chiwawa so my opinian is that the most recent spieces to a dog is the chiwawa
Some animals that move in groups include wolves, buffalo, zebras, and fish such as sardines and anchovies. Moving in groups can provide protection from predators, allow for better foraging opportunities, and aid in reproduction and social bonding.
Because of counter-current exchange, fish gills are the most efficient at gas exchange. This is followed by the continuous flow of bird lungs (due to their system of air-sacs). I don't know which animal exactly, but look to the fish for your answer.
Most animals do not live in family groups. Some animals that do include horses, lions, and dolphins.
it's the mammal
the animal is an herbivore they live by the solar energy
Butterflies do indeed take part in the exchange of gasses. They need oxygen to breathe just like most living animals.
Like most canids, Huskies are pack animals.
The superlative of efficient is "most efficient."
Carbon dioxide (CO2) and Oxygen(O2)
Different animals prey on other animals. In most cases, the carnivores are the ones that will prey on other groups of animals. A good example is a lion preying on an antelope.
They are dumb in comparison to humans, but they get over the average, seeing as there exists so many invertebrates.
