NATURAL HISTORY 
PILOT FISH. 
The Pilot Fish has a long body, with 
smooth scales, resembling that of a tench. 
Its back and sides arc of a deep blue colour, 
but its belly is lighter. The mouth is small, 
the jaws equal in length, and furnished with 
small teeth; the palate also has a row of 
teeth in front, similar to those in the jaws, 
which are somewhat curved; and the tongue 
has teeth all along. The shark is generally 
attended by one or more of these fish, who 
act as a sort of guide when in search of 
prey. It is an inhabitant of nearly all the 
seas of hot climates. They are frequently 
observed to swim round vessels, probably to 
catch the offal which is thrown overboard ; 
and even to accompany them into port.
