 MITSUKURINA OWSTONI Jordan 



Tenguzame (Goblin- Shark) 

 A huge example, 353 centimeters long, forwarded without ex- 

 amination to the United States National Museum. This is the 

 third example taken, the first being in the Imperial University of 

 Tokyo, the second in the Museum of Brussels. Mr. Owston writes : 



" I have several duplicates of this now, but the one I send is the 

 longest so far obtained. This shark is taken mostly at Kozu near 

 Odawara — on the chart 35°. 16 x 139°. 17 E. gives the exact spot, 

 where it will be seen there is a bank with 52 fms. on it close to 

 depths of 300 to 400 fms. I imagine these sharks come on to this 

 bank to breed, as mostly females are taken, and in the spring-time 

 only. They are caught in naname (7-mesh) nets, which are set at 

 the upper edge of the bank, so catching the fish when they come 

 up from the deep. Oil is extracted from the liver, but the flesh is 

 used only for fertilizing purposes. 



" This shark appears to be fairly well known at this particular spot 

 only, where they call it Tengu-zame, Goblin or Elfin Shark. I 

 showed a figure of it to half a dozen fish-mongers at Odawira, only 

 four miles away, and not one of them had even seen or heard of 

 such an animal. Kuma Aoki of Misaki knew nothing about this 

 shark being found at Kozu, although I believe he has fished on the 

 very ground. Kuma took a small one recently off Okinose, 10 miles 

 south of Misaki, by shark lines, and they have been taken on the 

 coast of Izu also by line."
