Do you know cold blooded animals? In this world there are many types of animals that live around the human environment. The animals are then grouped by type. One of them is grouping based on the temperature of the environment.
For example, animals that have a higher internal body temperature when compared to the outside body temperature. These types of animals are referred to as poikilotherms or cold-blooded animals.
The body temperature of these animals is caused by environmental influences. This type of poikilothermic or cold-blooded animal is a nation of reptiles, fish, and amphibians.
Based on research that has been published in an article entitled "Proceedings of the National Academy of Sciences (PNAS) online", it is known that from various distances, the temperature of each species changes its body temperature based on environmental temperature, so that environmental temperature is the dominant factor of bloody animals. This cold is to control the geographic variations in their lives.
In addition, there are other factors, such as local factors that also have an important role in their lives. Here are some poikilotherms in human life.
Cold Blooded Animals - Fish
The sizes of these cold-blooded beasts vary. There are whale sharks which are very large and measure up to 14 meters, as well as stout infantfish which are as small as 7 mm. Fish live in a very mysterious aquatic habitat.
In the sea for example, or a lake in which there is a mysterious life with many unpredictable animals. These mysterious animals are often thought of as "fish," even though they are not, such as whales, squid, and mermaids.
Fish are cold-blooded animals that can be found in almost all waters, both salt water, freshwater and brackish. However, waters that are too salty like the Great Salt Lake can't be a habitat for fish. These creatures are also often kept as human pets and cultivated in aquariums as ornamental fish.
Besides being cultivated, these cold-blooded animals are a very good source of food for the development of the body. For this reason, many fishermen in various waters are willing to spend their lives in the ocean to catch fish.
Fish has a very rich content of benefits and can be used as a source of body protein. The content in cold-blooded animals is also very nutritious and beneficial for the health of the human body.
As for food, the following is the nutritional content of fresh fish and its benefits.
Fish meat is very easy to digest because of the short protein fiber it contains.
Fish is very good for consumption by infants and pregnant women. This is because fish meat contains omega 3 which functions in the process of fetal brain development. In addition, omega 3 is also beneficial for the development of vision and nerve function in infants.
In addition to having iron which is very easy for the human body to absorb, fish also contains many vitamins. Like Vitamin A, which is found in fish liver oil and is very useful for children in preventing blindness.
It also contains vitamin B6 which can help the metabolism of amino acids and fats in the body and prevent nerve damage and anemia. Vitamin B12 is very important in helping the body's fat metabolism, forming red blood cells, as well as preventing nerve damage and protecting the heart. The presence of vitamin D in fish and meat liver oil is beneficial for growth and strengthening bones.
Fish is very good for stimulating cell growth in the toddler's brain because of the rich amino acids in fish.
There is iodine which can prevent the inhibition of children's growth and prevent the occurrence of goiter.
There is selenium which is useful in helping the body's metabolism as well as oxidants that can protect the body from free radical attacks.
Fish is also good for the health and strength of teeth in children because of the fluoride content in fish.
There is also zinc which can help the performance of hormones and enzymes.
To get the content in fish that is rich in benefits, then consume fish that are still fresh because the nutritional content is still maintained.
Cold Blooded Animals - Reptiles
Reptiles are animals that have four legs and reproduce by laying eggs. However, there are some reptiles that reproduce by giving birth. Usually they will feed their fetuses with a type of placenta that is similar in shape to mammals. This cold-blooded animal can be found on almost all continents, except Antarctica.
These cold-blooded animals have very diverse sizes, for example for the type of small gecko measuring 1.6cm. Then reptiles such as crocodiles usually weigh up to 1 ton. Although many of them are wild animals, many poachers are trying to catch them. This is because reptile skin is very suitable for use in the production of clothing, bags, shoes, and accessories.
Cold Blooded Animals - Amphibians
At the time of dripping, the larvae will later adjust to where they are so that they will breathe using gills. After a while, these larvae will have a changing shape where they will become adults and are shaped like their parents. Not only physical changes, but also respiratory organs.
Adult animals will breathe using lungs and live in drier areas. In Indonesia itself, some of the amphibians that can be found are frogs, salamanders, and caecilians.
To make it easier to identify amphibians, here are their characteristics.
In addition to having a body full of mucus, this cold-blooded animal has a heart with two chambers, namely one and two chambers.
This cold-blooded animal has two pairs of legs, each of which has a swimming membrane and is located between the toes. Its function is to swim and jump. In addition to the legs, the eyes of these animals also have a membrane in their eyes called the nictitating membrane and is very useful when diving.
These cold-blooded animals when they are still in the form of larvae or tadpoles breathe using gills. But his breathing apparatus changed after he turned into an adult. The respiratory organs are the lungs. The skin and nose will have valves to prevent water from entering the oral cavity when diving.
The way of reproduction is by releasing the egg to be fertilized by a male outside the mother's body.
We can find many cold-blooded animals in Indonesia. The existence of these animals shows how great God's power is to be able to create very diverse creatures to coexist with humans.
