The creatures in the Cambrian Explosion lived under water because most of them had shells that they used to protect them
All life was in the water in the Cambrian. Neither animals nor plants had evolved to the point where they could exist out of a marine or fw environment for many millions of years. Although a few land plants and fungi showed up in late Ordovician it was early Devonian before land-dwelling invertebrates emerged and mid-Devonian before the first land vertebrates appeared.

Why aren't humans amphibians?
amphibians are creatures that can live in water or on land, that does not mean that if we build a dome underwater and live their that we are amphibians.Amphibians can breathe underwater and on land, and since humans can't breathe underwater without the help of special equipment we are not amphibians.
These creatures are basket-shaped and live in colonies?
Sponges are basket-shaped creatures that live in colonies attached to surfaces underwater. They are filter feeders that rely on water flow to bring them food.
What is the study of underwater creatures?
The study of underwater creatures is called marine biology. Marine biology focuses on the biology, ecology, and behavior of organisms that live in saltwater environments, such as oceans, seas, and estuaries. Marine biologists study a wide range of organisms, from microscopic plankton to large marine mammals.
Are frogs underwater creatures?
Frogs are amphibians. That means they can live on land, but they must return to water alot to lay eggs and breathe, whereas toads are land animals, so if you live in a house far from any water bodies or out in the country without ponds the pads/frogs you see in your garden are most likely be toads. So yes, frogs may be underwater creatures but they roam land aswell
All the under water sea creatures?
If you mean, "are all under water creatures, sea creatures?" then no. The term SEA is for the ocean and there also can be creatures in freshwater. Also some creatures that live in water such as some snakes and sea turtles come out of the water every so often, so they are no total sea/water creatures. Fish are underwater creatures though.
Why creatures can live in water?
If by creatures, we mean animals, they require oxygen to survive. Humans get oxygen from the air by using their lungs. Underwater animals can get oxygen directly from the water (water contains dissolved oxygen) by using their gills. Other animals don't have gills (like dolphins) so they live underwater but come up to the air every now and then to get their oxygen. Life in general is very good at living in water. For billions of years, creatures were ONLY able to live in water. Land animals, like us humans, evolved later to live on land so now we are so poorly adapted for life underwater that it would kill us.
Can a snail live underwater?
Yes, there are types of snail that can live underwater.
Can dead people live underwater?

How are dolphins kind of fish?
Dolphins are not fish they are mammals or air breathing creatures that live underwater and come up for air like whales . ps.dolphins are part of the whale family
Do frogs live underwater or above?

Can you live through an explosion?
It all depends on how big the explosion was or how close you are.
Can all snails live underwater?
