What are animals that live in water called?
Animals that live in water are called aquatic animals. They have adapted to live in water and have various features that help them survive in this environment.
Aquatic animals come in a wide variety of shapes and sizes. Some of the most common types of aquatic animals include fish, amphibians, reptiles, and mammals. Fish are the most diverse group of aquatic animals, with over 30,000 known species. Amphibians are animals that can live both in water and on land, such as frogs and salamanders. Reptiles are cold-blooded animals that typically live in water, such as crocodiles and turtles. Mammals are warm-blooded animals that typically give birth to live young, such as otters and seals.
Aquatic animals play an important role in the ecosystem. They help to control the population of other animals, and they provide food for other animals. Aquatic animals are also a source of food for humans.
The study of aquatic animals is called aquatic biology. Aquatic biologists study the behavior, physiology, and ecology of aquatic animals. They also study the interactions between aquatic animals and their environment.

Aquatic animals are a fascinating and diverse group of creatures. They play an important role in the ecosystem and provide us with a variety of resources. We must do our part to protect these animals and their habitats so that they can continue to thrive.
Diversity
The diversity of aquatic animals is one of the things that makes them so fascinating. They come in all shapes and sizes, from tiny plankton that can only be seen under a microscope to large whales that can weigh up to 200 tons. This diversity is due to the fact that aquatic animals have adapted to live in a wide range of habitats, from freshwater rivers and lakes to saltwater oceans.
The diversity of aquatic animals is also important for the health of the ecosystem. Different species of aquatic animals play different roles in the food chain, and they help to control the population of other species. For example, plankton are a food source for many small fish, which are in turn eaten by larger fish. Whales are top predators that help to keep the population of other marine animals in check.
Understanding the diversity of aquatic animals is important for a number of reasons. First, it helps us to appreciate the complexity of the natural world. Second, it helps us to understand the role that aquatic animals play in the ecosystem. Finally, it helps us to make informed decisions about how to protect aquatic animals and their habitats.
Habitat
The habitat of an aquatic animal is an important factor in its survival. Aquatic animals have adapted to live in a wide range of habitats, from freshwater rivers and lakes to saltwater oceans. Each type of habitat has its own unique set of challenges and opportunities.
- Freshwater habitats: Freshwater habitats include rivers, lakes, ponds, and wetlands. These habitats typically have a lower salinity than saltwater habitats. Freshwater aquatic animals have adapted to live in this type of environment, and they have evolved a variety of strategies to deal with the challenges of freshwater. For example, some freshwater fish have evolved the ability to breathe air, while others have evolved the ability to lay eggs in moist soil.
- Saltwater habitats: Saltwater habitats include oceans, seas, and estuaries. These habitats typically have a higher salinity than freshwater habitats. Saltwater aquatic animals have adapted to live in this type of environment, and they have evolved a variety of strategies to deal with the challenges of saltwater. For example, some saltwater fish have evolved the ability to excrete excess salt, while others have evolved the ability to drink saltwater.
The habitat of an aquatic animal can also affect its behavior. For example, some freshwater fish are territorial, while others are schooling fish. Some saltwater fish are predators, while others are filter feeders. The behavior of an aquatic animal is often adapted to the challenges and opportunities of its habitat.
Adaptations
Adaptations are the physical and behavioral characteristics that help an animal survive in its environment. Aquatic animals have a variety of adaptations that help them survive in water, such as gills for breathing and fins for swimming. These adaptations are essential for aquatic animals, as they allow them to move through the water, breathe, and eat.
Gills are specialized organs that allow aquatic animals to breathe underwater. Gills are made up of thin filaments that are covered in blood vessels. The blood vessels in the gills allow oxygen from the water to pass into the bloodstream. Fins are appendages that help aquatic animals to move through the water. Fins are typically made up of a thin, flexible membrane that is supported by bony rays. Fins can be used for swimming, steering, and balancing.
The adaptations that aquatic animals have developed allow them to thrive in a wide variety of aquatic environments. From the deep ocean to the shallows of a river, aquatic animals have adapted to survive in all types of water conditions. These adaptations are a testament to the diversity and resilience of life on Earth.
Food chain
Aquatic animals are an important part of the food chain. They provide food for other animals, such as fish, birds, and mammals. They also help to control the population of other species, such as algae and plankton. This helps to keep the ecosystem in balance.
For example, in the ocean, small fish eat plankton. Larger fish eat the smaller fish. Sharks and other predators eat the larger fish. This helps to keep the population of all of these species in check.
In freshwater ecosystems, aquatic animals also play an important role in the food chain. For example, in a lake, algae and other plants grow in the water. Small fish eat the algae and other plants. Larger fish eat the smaller fish. Birds and other animals eat the larger fish. This helps to keep the population of all of these species in check.
The role of aquatic animals in the food chain is essential for the health of the ecosystem. Without aquatic animals, other animals would not have enough food to eat. This would lead to a decline in the population of other animals, and eventually, the entire ecosystem would collapse.
Conservation
Aquatic animals are an important part of the ecosystem, but they are threatened by a variety of human activities. Pollution, overfishing, and habitat destruction are all major threats to aquatic animals.
- Pollution: Pollution can come from a variety of sources, such as industrial waste, agricultural runoff, and sewage. Pollutants can enter the water and harm aquatic animals in a number of ways. For example, pollutants can cause respiratory problems, damage the immune system, and disrupt reproduction.
- Overfishing: Overfishing occurs when fish are harvested at a rate that is faster than they can reproduce. This can lead to a decline in the population of fish, which can have a ripple effect on the entire ecosystem.
- Habitat destruction: Habitat destruction occurs when the natural habitat of aquatic animals is destroyed or degraded. This can be caused by a variety of human activities, such as land development, dam construction, and deforestation.
Conservation efforts are needed to protect aquatic animals and their habitats. These efforts can include reducing pollution, regulating fishing, and protecting habitat. By taking these steps, we can help to ensure that aquatic animals continue to thrive for generations to come.
