One Nation's rise.
The only land animals that we know of that have electroreception are the monotremes, the echidnas and the platypus.
And that's a completely different system to what you find in fish.
It comes from cutaneous cells, so like mucus cells.
It's thought that that works because the short-nosed echidna feeds on termites and termite mounds are very humid, so there's enough moisture for the electrical signal to conduct, whereas the long-nosed echidna lives in rainforests and very damp environments and feeds on worms.
And so again, the dampness enables electrical signal to be transmitted.
Electroreception is often referred to as a sixth sense and it's the way animals either produce or respond to an electric field and develop an image in their brain and they can either use it to navigate or the way we often think of it is that they actually use it to find prey and help them hunt.
The lamprey is the most primitive of the animals alive today with electroreception.
But the most common animal alive today with electroreception, which also has an incredibly long evolutionary history, known from around about 470 million years ago, is of course sharks.
handbrake of course sharks can sense your electric little heart flutterings that's all we need sharks they're actually the most electro sensitive animals alive today with pretty much all sharks having these ampulla of lorenzini these little flask filled sacks they're filled with this
conductive jelly and used to hunt but also to avoid predators.
