How did Freshwater Creatures survive the Flood? Part 1

The Flood of Noah’s Day practically destroyed the surface of the whole earth

God knew if Noah didn’t build an ark, every land animal would have gone extinct.

But what about the animals that couldn’t live on the ark?

Fish and other water creatures

First we’ll look at what they need to stay alive.  They need

  • oxygen
  • a way to balance the salt and water levels in their bodies
  • clean enough water that their gills don’t clog up
  • and a steady temperature

A world-wide Flood with lots of magma and superheated water would mess all of these things up, so how did the fish we see around the world survive it?

Shell conglomerate rockIf you’ve ever found a fossil in your garden or on a walk, you know that there are billions of sea creatures that did die. The whole earth is covered with them. Just like most of the land animals didn’t make it through the Flood year, most of the water creatures were killed and many turned to stone as a memorial to God’s judgment of people’s sin.

But enough survived to allow both the oceans and rivers to fill up with life again. So some had to survive.

Here are some of the ways we know of that God could protect some of these creatures during the Flood.

Water doesn’t always work the same way

It is sorted into layers depending on what is in it and how warm it is. Cold water sinks (until it freezes), and so does saltier water.  So, if a section of water is warmer, or lower-salt, it floats in layers above the rest of the water. Wind also will pull this warmer, less salty water out of the way allowing deeper, cooler water to rise. There is a deep layer of water that flows off of the Antarctic coast that is less salty than the water above it, but sinks because it is cooler.

Today there are some very interesting areas where salt and fresh, cool and warm waters mix (or rather don’t mix) and make a very complex layering, swirling water system.

The Amazon River is one of these places. There is so much fresh water flowing out of the Amazon that the surface of the ocean beyond its mouth is less salty for more than 100 miles [160 km]!

Trapped areas of water can be quite different from the open ocean as well. The Black Sea is unusual with the water near the surface being only about half as salty as regular sea water, but with deep water areas that are cooler and saltier. They have found a river running along the bottom of the Black Sea from the Mediterranean that is so much denser that is flows down like a waterfall at one point!

Was the Ocean that Salty to Begin With?

Something people almost never consider is how salty the original ocean would have been. There is exciting science showing much of the salt on earth came from deep underground like magma. The first ocean might have been a lot less salty before the Flood and only changed to close to today’s levels as the water picked salt up from the land and carried it down.

We also know that during the Flood there were pockets of water that didn’t get swirled around so badly. For example, Ayer’s Rock in Australia is at the bottom of one of these basins. This area would have protected some water animals from being swirled away.

Good Guesses

We can’t know exactly how God protected the kinds of sea creatures that are still alive today because we weren’t there and He didn’t tell us. But we know this: God cares for His creation. He is sad when our sin makes the world a painful and deadly place for His creatures.

The fossil record shows us that many of the varieties of all animals God originally created are not alive today. We also know that when Jesus comes back to earth as King, He is going to restore the waters to great fruitfulness. What a glorious time that will be!

Here’s an experiment you can do to see how this all works:  Home School Science Press: Saltwater and Heat Convection

Then said he unto me, These waters issue out toward the east country, and go down into the desert, and go into the sea: which being brought forth into the sea, the waters shall be healed.  And it shall come to pass, that every thing that lives, which moves, where ever the rivers shall come, shall live: and there shall be a very great multitude of fish, because these waters shall come thither: for they shall be healed; and every thing shall live where the river comes.  And it shall come to pass, that the fishers shall stand upon it from Engedi even unto Eneglaim; they shall be a place to spread forth nets; their fish shall be according to their kinds, as the fish of the great sea, exceeding many. Ezekiel 47:8-10

Land Bridge from Asia to North America during the Ice Age


If you remember from the Ice Age posts, we figure it took about 500 years for the ice sheets to be the biggest they got before melting. When all that water was trapped on top of the continents, it wasn’t filling up the ocean.

All scientists figure that the water levels were up to 394 feet (120 meters) lower at the peak of the Ice Age before slowly rising to the level we see today. As we know, people were busy spreading all over the planet during this time, so it makes sense that they would leave behind submerged ruins for us to find in the shallow seas around the world.

First have a look at this page on how there was once a land bridge between England and France.

Then have a look at some of the places we’ve found around the world:

Persian Gulf Oasis

Underwater Burial Cave in Mexico

Unesco Underwater Cultural Heritage. These aren’t all Ice Age remains, but a lot of them are!!

Human Construction under the Black Sea. Noah’s Flood Deniers love to say that the Flood story came from the catastrophic breach of the Mediterranean into the Black Sea basin. This didn’t happen until after the World Wide Flood of Noah’s day, but it probably did happen like they describe.

Bimini Road of the coast of Cuba. If you read this page you’ll notice a common technique for keeping information about uncomfortable things from the mainstream of science: just don’t publish it!!! Then you can claim that no one really knows, it’s all just a conspiracy, etc.

And another article about the Cuban coast showing that there was a whole city. Have a look at this quote about why they won’t admit just what it all is: “We’d prefer to stay away from that subject. This is something of great potential scientific interest, but it must involve serious authorities on ancient civilizations.” They’d rather protect their jobs than publish the truth.

Well, that should keep you busy, and certainly shows that people got around!!

Here’s an article from a Young Earth Creationist about these places and more: Ice Age end about 1500BC and a MAP

So the LORD scattered them abroad from thence upon the face of all the earth: and they left off to build the city. Therefore is the name of it called Babel; because the LORD did there confound the language of all the earth: and from thence did the LORD scatter them abroad upon the face of all the earth. Genesis 11:8,9
