It is a fact that is first on the list and might amaze you a little bit. Some say that the gentlemen will have more tendency to have a left-handed feature than the ladies. Studies suggest a person’s handedness can be recognized from the moment they are in their mother’s womb. Some theories also show that determining if a person is right or left-handed is because of heritage.

Being left-handed is a person’s preference in using their left hand to be their dominant hand in performing different tasks. In this world, about 10% of people have a more dominant left-hand than the other. According to a study, around 70% to 95% of our population is right-hand dominant. And among that population are the individuals who can either use their left or right hand in performing different tasks, though it’s rare for people to have that kind of ability.

After eating their feces, rabbits will digest the wastes again like it’s regular food. These animals have a couple of droppings; a softer black feces called cecotropes and the tiny black round feces. The cecotrope feces are what they consume, and they perform that process so that they can absorb some undigested food nutrients. They usually do this process once per day.

These animals are herbivores that do not hunt other animals but plants, they live mostly on eating the grass and weeds. But that type of diet is not always easily digestible. The moment that their food is already entered their tummies, food still has some nutrients that their systems need to work. The Rabbits and their hares can tackle the same issue with the digestion process that some people have given the name of the hindgut fermentation. In other words, Rabbits consume their own feces, and they re-digest it. The process is called Coprophagy, and this function is the same as the cows when they are munching their cud.

Birds Need Gravity so That They Can Swallow

Birds can’t munch their food, and they instead consume their prey as a whole. Their esophagus is large enough to eat bigger meals, and they depend wholely on the gravity so that their food will push down and later be in the stomach. To further elaborate this fact, here is a simple example when we eat our food, it goes through our food pipe or the esophagus, where series of contractions and relaxations are present that push the eaten food into our stomach.

Our esophagus helps us send our swallowed food directly from the mouth to our stomach. But in the cases of some birds, there is no peristaltic movement as their mouth is distinct and different from other mammals. Birds don’t have teeth, and their jaws are coated by a beak, which can be seen in various types. They don’t chew their food, and these birds’ esophagus is large enough for them to swallow bigger meals.

That’s why birds will heavily rely on gravity for pushing the food via the esophagus, to their crop from their throat, then later placed in their stomach by peristalsis waves in their crop. And that’s the reason why birds erect their head while they eat their food.

When people catch the lobsters from the water, and it bleeds during the process, at that moment, you might notice that the lobster’s blood is bright.

Or when people go to buy them from storing crate, during the process you can observe that the color of the lobster’s blood turns blue due to the high oxygen in the tank where they’re kept, the same things happen at the surface of the ocean water. There are proteins inside the lobster by the name of hemolymph and hemocyanin that turn changes their color into blue when there is more oxygen. Even if it’s a house or wild cat, their instincts don’t change at all, and cats that live at the house have similarly-programmed behaviors the same as the wild cats. Like their counterparts, pet cats have the tendency to sleep straight for the sixteen hours a day, regularly, in order to save their energy when it’s time to go hunting for the food.

Hemocyanin, a type of a protein serum which you can find in crustaceans and some arthropods. These include primitive and some aquatic insects which can retain the oxygen level that carries the function of the protein. Mollusks also evolved a different protein that people call hemocyanin and serve as an oxygen carrier. But it’s like developing differently from the hemocyanin of arthropod.

They don’t have to hunt for their dinner, and their meals are served, sometimes cat food or gourmet.
