Water, fresh water or ocean water or sea water, is definitely a dramatic sources of life in today’s world. It is home to various creatures, including animals like amphibian creatures like frogs, turtles and other under water animals.
We are generally unaware of such creatures. It is important to study under sea animals, under water animal life, frogs and turtles because such creatures are sensitive to delicate environmental changes like ozone depletion in the atmosphere or water quality. As amphibians act as environmental indicators, they help people in monitoring the indicators and observe other changes that could harm us.
As amphibians and other undersea animals play a vital role in the world’s ecosystem, creatures like turtles, frogs and toads help in the ways to destroy harmful insects in large quantities. Turtles act as scavengers in various water bodies. Amphibians and other under water animals provide a vital food source for other animals and, therefore, they are interesting to study.
Interestingly, most of the underwater animal species carry out their eco-logical roles without entering into a conflict zone with people.
Aquatic creatures like turtles mostly inhabit water bodies like rivers, ponds and lakes, while toads and frogs dare to lay their eggs in water. Most toads and frogs breed in ponds like vernal pools and other very shallow wetlands that are free from fish.
As turtles and frogs need different habitats at different times in the year, they turn vulnerable, if and when travel is involved.
Meanwhile, deep sea/ocean water is critical for survival for other aquatic creatures marine mammals like Blue Whale, which is the world’s largest marine animal, Bull Shark, an aggressive shark that lives in both fresh and salt water, Dolphin (which is an intelligent mammal having vocal and social activities.
Some of the other sea/ocean mammals include Elephant Seal, Estuarine Crocodile (found in Southeast Australian and Asian estuaries), Great White Shark, Humpback Whale (It is a majestic-looking black-and-white whale), Killer Whale (Orca) and Walrus (an Arctic marine mammal).
The aquatic ecosystems can largely be divided into two key groups based on their salinity and they are marine habitats and freshwater habitats.
- Marine habitats have high levels of salt concentrations, generally more than 1% and they include seas, coral reefs and oceans.
- Freshwater habitats have low salt concentrations, meaning less than 1% and they include ponds, wetlands, lagoons, swamps, rivers, bogs lakes and streams.
There are, however, some habitats where freshwater and saltwater mix together and they include mangroves, salt marshes and mud flats.
All these aquatic ecosystems majorly support different types of animals including amphibians, mammals, reptiles, birds, invertebrates and fishes.
– Rain water feeds freshwater rivers, streams and lakes and they are home to hundreds of thousands of animal species.
Oceans – They create the largest habitat on Earth with countless animal species living in the oceans that cover more than 75% of the Earth.
Coral reefs – They are the richest habitats for aquatic creatures on the planet and they provide shelter to hundreds of thousands of animal and plant species including reptiles, fish, echinoderms, crustaceans and invertebrates. The reefs are situated in the tropical and sub-tropical coastal regions.
