 Like the rest, it lives at the bottom, and feeds on crus- 

 SappMrine taceans an ^ small fishes. Cunningham 1 

 Gurnard alludes to a curious habit which this fish has 

 8 ' of spreading the pectoral fins when alarmed. 



A still larger fish is the Piper, so called from the vocal 



performances to which, like the rest, it is addicted. It is 



taken principally in the Channel, though not 



uncommon farther north. The largest of our 



gurnards, it grows to a weight of 5 Ibs. or more. In colour 



this gurnard is bright red above, white beneath. It is a 



more slender fish than the last, lacks the distinguishing 



blue pectoral fins, and has the edges of the bony plates on 



the snout strongly serrated. 



The Lanthorn Gurnard, smallest of our true gurnards, 



is recognised by its elongated dorsal fin, after which it 



Lanthorn is called in some parts the " long - finned 



Gurnard. g urn ard." It is red in colour, and has a 



bright silver band along the sides. It is said not to 



take a bait. 



In the little Pogge we have a kind of sea- armadillo, 



clad in a suit of impregnable armour. Like the true 



Pogge or bullheads, it is destitute of air-bladder. It 



Armed is regarded as commonest on our east coast, 



Bullhead. es p ec i a }i v j n ^he neighbourhood of estuaries. 



In colour yellowish grey, with black bands. 



The Beaked Gurnard is another armed fish, scarlet in 

 colour. It is but a straggler in our seas, and may at 

 Beaked once be recognised by the pointed bony pro- 

 Gurnard, jections before the head, beneath which there 

 are filaments, and the large plates of bone with which 

 the body is covered. Like the true gurnards, it has an 

 air-bladder.
