Essay on Aquatic Animals

Introduction

Aquatic animals are those animals that live underwater. There are various aquatic creatures that have special characteristics. A short essay on aquatic animals helps children to understand life in water and how these organisms adapt themselves for survival.

Aquatic animals that live in ponds, rivers, and lakes are known as freshwater animals. Aquatic animals that live in oceans and seas are called marine/ saltwater animals. Some aquatic species have the capability to live both in water and on land; they are jellyfishes, crabs, turtles, etc. Around 230,000 species of aquatic animals have been discovered, and still, marine enthusiasts look forward to discovering new aquatic creatures. Some aquatic animals are known for inhaling oxygen through their gills, while other aquatic animals breathe through their lungs. The main source of survival for the people living in coastal areas is aquatic animals. The National aquatic animal of India is the Ganges River Dolphin, found in the Ganges-Brahmaputra area.

Several aquatic species live in the water, such as mammals like whales, molluscs such as sea snails, cnidarians, also known as jellyfish, and crustaceans like crabs. Short essay on aquatic animals helps children understand about marine life.

Threat to Aquatic Animals

Due to several reasons, the lives of aquatic animals are in danger now. They are:

Oil spills in the oceans create a layer on the surface of the water and prevent the diffusion of oxygen to aquatic life. Due to the increase in the production and consumption of aquatic animals, many aquatic animals are now endangered species.

The high amount of chemical waste from industries, manufacturing companies, and oil refineries pollute the aquatic lifeforms. Global warming is another cause of diminishing aquatic biodiversity. The phenomenon increases heat in the oceans and other water bodies and affects the ecosystem of shellfishes, fishes, crustaceans, and other marine species.

Protection of Aquatic Animals

The government has imposed several rules to take strict measures against people harming aquatic animals. Some of them are:

The Marine Protected Areas or the MPAs have signed the law to protect and preserve the endangered aquatic life forms in the year 1999. The Government of India has passed The Maritime Zones of India Act 1976 to safeguard the marine environment and protect its species.

The Coast Guard Act 1978 focuses on the control of marine pollution, and the protection of the marine environment.

Conclusion

Aquatic animals are living organisms that stabilise the ecosystem and biodiversity of water. Hence, these organisms should be protected from extensive consumption to prevent imbalance in the ecosystem. Kids learning about aquatic animals helps them to protect the marine organisms from extinction.

Frequently Asked Questions

Why do aquatic animals need less skeletal support?

Gravity on land is heavier than in the water. Every living being inside water feels lighter. Hence, aquatic animals have less skeletal support than terrestrial animals.

Why do animals living in water have thicker bones?

Thick bone is an adaptation that marine organisms have for living in the water. Thick bones are heavier and help water-dwelling animals control their buoyancy, i.e. the ability to float.

What are aquatic animals?

Aquatic animals are those animals that live in water bodies, such as seas, oceans, rivers, lakes, ponds, etc. Examples of aquatic animals are fish, jellyfish, sharks, whales, octopuses, barnacles, sea otters, crocodiles, crabs, dolphins, eels, rays, mussels, and so on.
