Proton shark - KEEPING SHARKS WARM IN THE COLD

You will remain safe and anonymous.

These surface pores are connected to electrosensory cells by canals filled with clear, viscous jelly, which let the fish detect weak electrical fields emitted by other animals in the sea - even signals as subtle as 5 nanovolts per centimetre.

For this reason, we have to give the win to Surfshark.

Now, of the University of California, Santa Cruz, and colleagues have discovered that AoL jelly is an extremely good conductor of protons — something that could help to explain how it can transmit weak electric fields.
