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.
