slowly, snout to snout, open their mouths to the 
limit of their gape, and gaze, as it seems, for 
several seconds, as if in rapt attention, each at 
the patch of bright red on the other’s mouth.” 
A near view shows that there is haunt 
within haunt. There are sandy corners and 
seaweedy corners, sheltered coral basins and 
open reefs, shady places and illumined places, 
and all the different levels from the floor to 
the surface. Of course there are bold wan- 
derers that go everywhere, but on the whole 
each creature has its favourite and habitual 
corner, to which it is particularly well suited, 
especially as regards its colour and patterns. 
And different creatures tenant the same place 
at different times: thus, when evening ap- 
proaches, the day-feeding fishes disappear, 
and out of the recesses of the reef come night- 
feeding fishes, first in twos and threes, and 
then in schools. There are many “ Box and 
Cox” arrangements in Nature. 
The big result of close observation of the 
shore-haunt is to show that it includes a great 
variety of surroundings, and that many a crea- 
ture has a particular niche where it is most at 
home.
