Cuttlefish (Sepia, fig. 78). Four to ten inches long and half as 

 broad, in shape like a small, big-headed , heavily made 

 fish. They may be floating, but generally lie in corners 

 on the sand , which they resemble in colour. The dirty 

 colour of the water is due to the ink they squirt out when 

 disturbed.
