1062. Why have otters, seals, &c., web-feet?
Because, while the feet enable them to walk upon the land, they are equally effective in their action upon the water, and hence they are adapted to the amphibious nature of the animals to which they belong.
1063. Why do the external ears of animals of prey, such as cats, tigers, foxes, wolves, hyenas, &c., bend forward?
Because they collect the sounds that occur in the direction of the pursuit, and enable the animal to track its prey with greater certainty.
"Doth the hawk fly by thy wisdom, and stretch her wings toward the south? "Doth the eagle mount up at thy command, and make her nest on high?"
1064. Why do the ears of animals of flight, such as hares, rabbits, deer, &c., turn backward?
Because they thereby catch the sounds that give them warning of the approach of danger.
1065. Why has the stomach of the camel a number of distinct bags, like so many separate stomachs?
