Saltwater platypus surprise!
On the windswept ocean beaches of Kangaroo Island, off the southern coast of the Australian mainland, it was just another ordinary day.
The island is renowned as a place where you can get close to local fauna such as seals, kangaroos and koalas. Some international tourists aimed their video camera [actual image available only in Creation magazine] at one of Australia’s most famous native animals as it emerged from the sea and made its way up the sandy beach.1
Yes, the creature certainly matched the well-known descriptions of it which had for so long intrigued sceptical biologists: fur like velvet, a beaver-like tail, a bill that looks like a duck’s, and clawed feet useful for digging.2 The tourists were delighted and excited to be able to see for themselves a real live platypus in its natural habitat.
Or was it? ‘In the wild’, certainly, but was this platypus really ‘in its natural habitat’? Accompanying the tourists on the beach at that time was their Australian tour guide. In stark contrast to the visitors from overseas, Campwild Adventures tour guide Ben Combridge was dumbfounded (‘spun out’) to see this platypus come in to the shore, ‘riding in on a small wave’, and waddle up the beach. While the tourists were excited to experience what they thought was a standard encounter with local wildlife, the Australian knew better. As he told a news reporter: ‘I was—like—“That’s not meant to be here!”’1
Indeed. As an Australian myself, I was always taught that platypuses live in fresh water, not seawater, and are most usually found in mountain streams and creeks in eastern Australia—nowhere near a seashore environment.3
But when biologists heard of the seashore encounter with the Kangaroo Island platypus, their comments indicated that the platypus is a species that scientists still know little about.
‘When you think you know what they’re doing—they do something different’, said one platypus expert, describing this latest observation as ‘incredible’. Another expert who has successfully bred platypuses in captivity for more than 10 years, Dr John Wamsley, was just as candid. ‘I’ve never known of them going into the salty water’, he said. ‘Whether they can survive in salt water or not, I haven’t got a clue.’1
Well, clearly platypuses can and do frequent seawater without any apparent ill effects, for since this first witnessing of a platypus emerging from the sea, Kangaroo Island tour guides have reported other sightings of platypuses in saltwater rock pools in the area.
This discovery adds to the weight of evidence showing that many amphibians and water-dwelling creatures (e.g. crocodiles, salmon, eels, starfish) can tolerate large changes in salinity—thus helping to explain why both saltwater and freshwater creatures (which were not on board the Ark) were able to survive in the waters of the global Flood (Genesis 6–9).4
It is likely, though, that Noah took a pair of platypuses on board the Ark, as, although they are known to be able to spend up to 10 hours in the water,5 much of their time is spent on land. They dig their burrows on dry land, usually taking care to dry themselves before entering, and they will not enter a burrow if the entrance is below the waterline. Finding that platypuses can tolerate saltwater gives us further insight into how they managed to spread out from the Ark’s landing place in the mountains of Ararat—by swimming and walking their way to Australia. In the light of this new report, it’s possible that their migration route might have even included significant stretches of ocean.6,7

So, for Christians, we need not be surprised on hearing of yet another amphibian or aquatic animal, previously thought of as living exclusively either in fresh or salty water, being discovered to tolerate both. But having been an atheist once myself—a believer in evolution and completely ignorant of the Bible—I can understand why many are surprised when findings like this are announced. In fact, I remember in my younger days going on a holiday to Kangaroo Island, and standing on the bank of an estuary just a few hundred metres from the sea, looking out over the calm water and seeing something like a mole or a rat rise to the surface momentarily a few metres away from me, before submerging again. Puzzled and startled, I remember thinking, ‘What was that? Surely not a water rat here in salt water—but what else could it be?’ It never occurred to me at that time that I might have been looking at a platypus … .8
So I can well understand the tour guide’s astonishment as he stood on the beach with his group of tourists: ‘We didn’t take much notice at first—it just looked like a bit of seaweed coming in on the wash’, he said. ‘But as the water washed back, it kept on coming.’

Having fished on the U.S. gulf coast for several years, I can say without a doubt that there are several different species of fish that can live in both salt and freshwater. I'm not just speaking of those species that live in the brackish bays or bayous either. I've seen freshwater Garfish leisurely swimming just off the beach before, several miles from the nearest body of freshwater.
Texas now has several rivers and inland reservoirs that boasts having very healthy stocks of Redfish. This is a species that can be routinely caught 20 -30 miles out into the Gulf of Mexico.
Freshwater or saltwater, it's all the same to these fish.
And for many others, too--see chapter 14 of The Creation Answers Book: How did fresh and saltwater fish survive the Flood?
Slowly but surely God is revealing the answers to us, in His time which is always the right time. What an amazing God we serve!
