iiig the animal to dart forward, but this method of progression 

 is rare in comparison with the backward darting. They can 

 also swim slowly forward when propelled by movements of the 

 fin. Scjuids feed upon small fishes, Crustacea, and even the 

 young of tlieir own species, and they are themselves devoured by 

 numerous fishes, tlie sperm whale and seals. In killing a small 

 fish they bite a piece out of the back of the neck. They capture 

 their prey by darting rapidly backward, swinging quickly to one 

 side and seizing the victim in their sticker-ljearing arms. 



Very commonly they become stranded in their backward dart- 

 ing flight, and tlien thrash helplessly upon the shore, forcing water 

 out through the siphon and ejecting their jet-black ink. The 

 shores of ilaine arc often strewn with squids that have pjerished in 

 this manner, this being especially noticeable after moonlight 

 nights. Indeed, the fishermen take advantage of the attraction 

 squids display for light by placing a beacon in the bow of their 

 boats and slowly rowing ashore, thus stranding the congregated 

 animals. 



They often swim in schools, especially during sjiring and early 

 summer. During some years the water fairly teems with them, 

 and then again none will be seen for long periods of time. As they 

 dart through the ocean their color changes instantly to match their
