There are many animals in the sea, and various fish swim freely in the water, adding a lot of vitality to the underwater world. Lets learn how to draw undersea animals. The editor has compiled pictures of childrens simple drawings of marine animals. I hope you all like them!

Introduction to marine animals
Marine animals are heterotrophs in the oceanThe general name of organisms. The ocean is an important life support system, and marine animals are an important part of the biological world.
There are many categories, and the morphological structure and physiological characteristics of each category can be very different. Tiny ones include single-celled protozoa, while large ones can be over 30 meters long.meters and can weigh more than 190 tons. There are marine animals from the sea to the bottom of the sea, from the shore or the intertidal zone to the bottom of the deepest trenches. A general term for heterotrophic organisms with very different morphological structures and physiological characteristics in various categories in the ocean. They do not perform photosynthesis and cannot synthesize inorganic matter into organic matter. They can only live by feeding on plants, microorganisms and other animals and their organic detritus.
There are currently 160,000 to 200,000 species of marine animals, which are diverse in form, including microscopic single-cell protozoa, higher mammals - blue whales, etc.; they are widely distributed, from the equator to the polar seas, from the sea surface To the depths of the ocean floor, from the coast to the bottom of ultra-abyssal trenches, there are representatives. Marine animals can be divided into three categories: marine invertebrates, marine protozoa and marine vertebrates.
Distribution
Fauna in the ocean: The living conditions in the ocean are relatively consistent and the area is vast. In addition to fish, whales and planktonic animals, Animals and swimming animals such as cephalopods and jellyfish. In the deep sea layer, only animals that do not depend on plankton for survival are found. In many ocean areas, ocean currents bring nutrient-rich deep seawater to shallower layers, increasing fish production in the shallower ocean zones. Benthic animals living on the seabed include sessile animals, such as sponges, coelenterates, nereids, etc., and mobile animals, such as crustaceans, mussels, various annelids, echinoderms, etc. Coral animals are most fully developed in tropical oceans. Coral reefs are formed by the deposition of chalky skeletal material from a large number of reef-building animals and plants, especially corals and bryozoans. Animals are densest and most diverse in coral reef environments.
