50 Water Animals Name | Aquatic Animals List A-Z

As we all know, the Earth is made up of 71% water. And although that may be alarming for some, it’s also incredibly intriguing and leaves plenty of opportunity for exploration. In this blog post, we’ll be exploring 50 different aquatic creatures—both saltwater and freshwater. These animals can be found in all corners of the world, from the Great Barrier Reef to the Amazon River Basin. So without further ado, let’s dive into our amazing undersea world!

Water animals, also known as aquatic animals, live in water. That might seem like stating the obvious, but it’s an important distinction to make. Animals that live on land are tetrapods, meaning they have four legs. But aquatic animals come in all shapes and sizes, from turtles and crocodiles to dolphins and whales. Some, like the manatee, are even able to spend time on land. What all water animals have in common is that they have adapted to life in an aquatic environment.

This can mean anything from having webbed feet for swimming to having gills for breathing underwater. In some cases, it even means being able to swim up rivers and climb trees! Whatever the case may be, these adaptations allow water animals to thrive in their watery homes.
