Did you think that volcanoes could only be on land? No you were mistaken there are more than five thousand volcanoes underwater that are of various sizes.

It is not necessary for these volcanoes to be under deep water, these can also exist under shallow water and when these shallow water volcanoes erupt, they throw the magma on the surrounding land area as well.

The coral reefs are found in shallow, warm water only, where the temperature of water is mostly constant throughout the year. Have you ever wondered what exactly are these reefs made up of? These are made up of as many as thousands of corals, and when this coral dies, it leaves behind the calcium carbonate skeleton. Further, the cycle starts again when the young ones attach themselves to the old skeleton. And so on, every generation builds up themselves on the prior generation.

Coral reefs start at a length of a few centimeters and go on to attain an unimaginable size - the Great Barrier Reef in the Pacific Ocean being one of the best example of the same. Coral reefs are considered largest living structures on the planet.

Sharks have been the most feared and wild marine creatures. These animals have been prowling in the oceans for around 400 million years and have evolved into 440 different species. Sharks are known to live for many years.

Sharks have excellent eyesight and can see objects moving even in dim light. Strong smell and touch senses make them amazing and smart predators. With the gift of such wonderful sensory abilities, their prey animals can hardly escape these deep water beasts

There are about 32 types of dolphins and all are unique in their color and body constitution. Looking at them together will really fascinate anyone! While these 32 types thrive in salt water, there are five other types of dolphins who live in the freshwater. Bottle nose dolphin, the Killer Whale, the Common dolphin, the Black dolphin and Dusky dolphin are some of the types of dolphins.

an adult dolphin eats nearly 20 to 22 kilos of fish every day!! The eating habits of dolphins are dependent on the area where they thrive and the season of the year. Seasons in which fish like mullet, mackerel, herring, cod are found abundantly, the dolphins have a party time!
