Can slime last for 100 million years? Yes, yes it can.
Scientists have discovered the fossil of an ancient hagfish with traces of its slime still preserved.
The hagfish is a spineless creature that lives at the bottom of the ocean. It's been around for 500 million years and looks a bit like a swimming sausage.
It doesn't have jaws but does has a special way of defending itself - by letting out slime!
In the creepy video below, you'll see a hagfish defending itself against a shark. When the shark bites the hagfish, its mouth and gills are quickly covered in slime and the shark has to back off, or face suffocation.
It's not good to crash a car at the best of times, but imagine doing it with 3,400kg of hagfish in the back.
The picture above shows a slime covered car in Oregon, America back in 2017. It was covered in hagfish slime after a truck overturned on the road. The truck was helping deliver hagfish to South Korea where they are considered a delicacy.
No one was injured in the crash but 3400kg worth of hagfish goo was released all over the cars and road.
