Who says the ABC doesn't know how to make a good headline? It certainly got my attention.
The sharks use a gel like substance on their heads to pick up electrical signals from the water.
The process is called electroreception and it blocks out the shark's other senses which is why it will go for prey that is bleeding instead of an easier target.
The gel contains various proteins and salts, so it's simular to mucus, only with a jelly like consistency. Basically it's shark snot (and you thought I was kidding) according to researcher, Dr. R. Douglas Fields.
