PIPE-FISHES 39 
amongst which they dwell as to pass un- 
noticed by their enemies. Unlike the Tube- 
and young devolves upon the males. The 
young are borne in a pouch, but, ventral 
fins being wanting, this is formed by a fold 
of skin developed from each side of the 
trunk and tail, the free margins being 
united in the middle line. Here the eggs 
remain till they are hatched. But the 
pouch is by no means done with after this 
event, for the young continue to occupy 
it for some time, returning when danger 
threatens — a habit which recalls the custom 
of the young of the kangaroo. Mr. Yarrell 
relates a curious fact which he gleaned from 
some fishermen —to wit, that if they take a 
pipe-fish, open the pouch, and drop the young into the sea, they will not disperse, but hover 
around the spot, as if waiting for their parent. Then, if the newly opened fish be held in the 
water, the young immediately return and enter the pouch. In another species of pipe-fish 
the eggs, instead of being carried in a pouch, are held by a sticky secretion to a groove 
in the under surface of the parent. This groove would seem to indicate the beginning 
from which the complete pouch has been developed. The pipe-fishes swim in a very 
peculiar manner, holding the body now in a vertical, and now in a horizontal position, 
accompanied by contortions of every conceivable kind, poking their long snouts into bunches 
of seaweed in search of food as they go.

BLACK-SPOTTED GLOBE-FISH 
Globe-fishes possess the power of inflating the body with air, when 
they float at the surface, and thus escape enemies
