Nice, always loved the way ghost knives swim, hypnotising

 
But a marvel of nature to adapt and swim with one long fin to suit their enviroment and body types etc.
 
Engineering has just touched the tip of the iceberg with this I reckon, a while yet before they will make a truly agile robot that mimics a ghost knife. Its a start, the rest is inevitable.
