Distributed over all warm seas, and occasionally seen off our coast. Grows to fifteen feet in 

 length, half of which is made up of the greatly elongated tail ; this last is used to splash the surface of 

 the sea near a shoal of fish so as to frighten them together. A common idea that the Thresher attacks 

 whales apparently rests upon erroneous observations.
