A stained neural arch from a 330 cm (total length) female 

 bluntnose sixgill shark. The arch was soaked in I9c silver 

 nitrate for 7.25 hours, but the inner portions of the arch 

 were barely stained. Ten bands are indicated by dots, but 

 the first four are difficult to determine. The fourth band is 

 labelled with the number four

Number of bands observed in neural arches by total length 

 (cm) of sixgill shark. Dots represent females; open circles 

 represent males. As the total length of the shark increases, 

 the number of annuli observed increases.
