In 2017 an Australian tour operator out at
sea photographed something pretty spectacular and very rarely seen. That was a saltwater crocodile and four tiger
sharks in the same vicinity. The reason they were around each other is
all of them were feasting on the carcass of a whale. Unfortunately for us, they didn’t get into
a fight. Newsweek wrote, “There was no aggression
between the animals and they appeared to be respecting each other’s space, even eating
from different parts of the whale.” But we did find one case in which the two
animals did go toe-to-toe, also in Australia, and in the U.S. alligators have gone up against
sharks. You might be surprised what happened, but
we won’t tell you about the result just yet. Let’s first do some fight analysis. So, the in red corner we have the shark. The problem is, there are something like 440
species of shark so we have to know what kind of shark we are going to pit against our croc. In the interest of making this show exciting
we aren’t going to talk about softy sharks such as the nurse shark or leopard shark. They are not really the most violent species
and wouldn’t even hurt a hair on your head. If we are going to put a shark up against
one of those beasts called crocodiles, we think it has to be the great white. It’s a formidable killer and that’s why
it was the star of the utterly terrifying movie, Jaws. The great white can claim to be the shark
that kills most humans, and while the tiger shark is certainly handy in a fight, it’s
the great white that we all know and fear. Another good thing about this face off is
that a great white could possibly get into a scrap with a crocodile because in Australia
the two could meet in the ocean. There are some folks that probably didn’t
even know that crocs swim around the ocean, but if you’re Australian you’ll have seen
news reports of these beasts taking human lives. If you think it’s safe to go out in the
water and snorkel, be sure to check if the danger signs are up. Saltwater crocodiles seem to take the most
human lives among all crocodile species, so it’s a good croc to pit against our great
white. We should also tell you that saltwater crocodiles
can get very big, with the biggest croc ever recorded being the saltwater variety and going
by the name of Lolong. It was killed in the Philippines in 2011 after
killing a farmer and a little girl and perhaps a few others. These things are no joke, so we can say with
certainty if we put a great white against a saltwater croc we have the fight of the
century. Ok, time to do the weigh-in. We’ll work with averages here, not the biggest
ever found. A fully grown great white shark can weigh
anything from 680 – 1,100 kg. In pounds that’s 1500 – 2425. Yep, that’s big and it’s one reason humans
are so easily torn to shreds by these things. Females can get even bigger, and they can
measure on average 4.6 to 4.9 meters (15 to 16 feet). Let’s now look at our saltwater crocodile
at the weigh-in. In their case the males are much bigger than
the females, so let’s say our fight will be between a female great white and a male
crocodile. That male on average will weigh something
like 1,000 –1,075 kg. That’s 2,205 – 2,370 pounds. They usually grow to about 6 meters, or 20
feet. So, in terms of weight the two are very similar,
and let’s just say for this show the fighters are both fairly equal in weight. The croc is a bit longer but there’s nothing
we can do about that. It’s not that different, so just imagine
this fight being like that recent heavyweight contest between Andy Ruiz and Anthony Joshua. In that case the short guy won, but it might
not be the case for this fight. What’s good about this battle is both of
the animals can hold their own, and it’s said where they go they rules the waves. They really wouldn’t want to get into a
fight, because animals don’t often bite off more than they can chew. Well, today they have no choice. They are fighting and that’s it. Both animals are fast, and the crocodile might
move at 29 km/h when at top speed. That’s 18 miles per hour. The great white has the upper hand here as
it can reach speeds of 56 kph, or 34 miles per hour. Rushing in at that speed might be a problem
for the croc, but the croc has one massive ace up its sleeve. This ace is the fact the saltwater crocodile
has the highest bite force of any animal in the world. Yes, you heard that right, it bites harder
than any living thing. If it gets hold of a shark it’s going to
hurt to say the least. That bite force can be 3,700 pounds per square
inch. That might not mean much to you, but a great
white shark has a bite force of way less. This is how one scientist described the bite
of this animal, “The strongest bite clearly belongs to the saltwater crocodile. It would be easier to lift a car off of your
leg than to open up the jaws of a saltwater crocodile that has clamped down.” So far, the croc has the slight weight advantage
and size advantage and it can bite harder, but the slippery shark has speed, and we all
know speed is important. We should also add now that the crocodile
does hunt some quite large marine life, including sharks, but only small ones usually. We have seen a photograph of a saltwater crocodile
with a bull shark in its mouth, but that’s no great white. Sharks, too, though, eat other sharks as well
as lots of large marine life including small whales, dolphins, etc, so they are certainly
no pushover. In terms of weapons, we know the croc has
that incredible bite force and we know the shark’s bite force is strong, too, but on
the shark’s side is its maneuverability. If it gets something in those serrated teeth
it has it will then violently move its head from side to side. It’s a ripper rather than a chomper. With its ability to move in and out fast and
take chunks out of the croc, perhaps the crocodile would be ripped apart slowly. It’s not an easy match to pick a winner,
with some experts saying the saltwater crocodile is almost invincible in its natural territory,
and that includes being the toughest animal among sharks and other apex predators. It might not have the speed or agility to
outfox the shark, but if it gets that shark in its mouth – which it will in a fight
to death – it will cause so much damage. The shark on the other hand won’t so easily
cause the same kind of injury because the croc has better armor. The shark might get a chunk, but the bone-crushing
croc will no doubt deliver a much more harmful blow when it bites. If it gets a fin the shark will be in serious
trouble, but if that shark takes a chunk of the croc it will likely not do enough damage
to make the croc retreat. If the shark does get a big bite it could
just swim away and hope that the croc bleeds out. We looked at what so-called experts think
of this battle, and it seems a lot of people seem to think that the shark would not recover
from a crocodile bite Back to the beginning of this show and the
news report about a great white and a crocodile fighting over fish. This happened in Mexico and the croc attacked
and the shark swam off with its fin between its many teeth. It didn’t want to fight. The croc got the fish. We think this would happen time and again
because the croc is just too imposing and the shark is too astute to take a risk in
fighting the croc. The croc will be stubborn, though, and won’t
budge an inch. If it does come down to the fight it will
be whoever gets the first bite in. If the croc gets its mouth on the croc the
shark will suffer too grievous an injury to survive. If the shark can rush in and get a chunk and
then wait for the croc to bleed out it will win. With all this in mind, this fight would very
likely end with both great animals dying. It’s an unhappy draw. Or do you disagree? Tell us what you think about this fight in
