Hagfishes are incredible! They can stop a would-be predator within seconds with a mouthful of slime. Ichthyologists at the National Museum of New Zealand (Te Papa Tongarewa) have just published a fascinating paper on hagfish behaviour in the journal Nature.

The movies below, show hagfishes 'sliming' would-be predators to avoid being eaten, and actively hunting a bandfish. The full Nature paper can be downloaded as a pdf.
