koi fish drawing

Hi everybody, welcome to anew NIL-Tech drawing tutorial: "Fish". Fish are involved in our society through the pet industry, the recreational fishing industry, and fish farming. Fish are likewise crucial to the ocean, lake, and river ecosystems. While fish are commonly thought to lack intelligence and also emotional capability, they remain, in fact, sentient creatures. They have feelings and can experience both positive and negative emotions.


Here are some interesting facts about Fish:

1. Lungfish can live out of water for several years. It produces a mucus cocoon and burrows itself under the unbaked earth. It takes in air with its lung with a built-in breathing tube that brings leads to the surface. A lungfish has both gills and a lung.

2. Some fish, such as the great white shark, can increase their body temperature. This helps them hunt in cold water.

3. The oldest known age for a fish was an Australian lungfish. In 2003, it was still alive and well at 65 years old.

4. Fish use a variety of low-pitched noises to convey messages to each other. They moan, grunt, croak, boom, hiss, whistle, squeak, shriek, and wail. They can also rattle their bones and gnash their teeth. However, fish do not have vocal cords. They use other parts of their bodies to make sounds, such as vibrating muscles against their swim bladder.

5. Fish can form schools consisting of many fish. They use their eyes and something called a lateral line to hold their places in the school. The lateral line is a row of pores on the fish's sides from head to tail. Unique hairs in the pores can sense changes in water pressure from other fish or predators' motions.
