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.
