It has a most imposing array of sharp, conical teeth outside the lips--objects of dread to the fisherman, for it can use them effectually.

One which we picked up dead had killed itself by swallowing another fish, which, though too large for its stomach and throat, could not be disgorged.
This fish-hawk generally kills more prey than it can devour.

It eats a portion of the back of the fish, and leaves the rest for the Barotse, who often had a race across the river when they saw an abandoned morsel lying on the opposite sand-banks.

The hawk is, however, not always so generous, for, as I myself was a witness on the Zouga, it sometimes plunders the purse of the pelican.

Soaring over head, and seeing this large, stupid bird fishing beneath, it watches till a fine fish is safe in the pelican's pouch; then descending, not very quickly, but with considerable noise of wing, the pelican looks up to see what is the matter, and, as the hawk comes near, he supposes that he is about to be killed, and roars out "Murder!" The opening of his mouth enables the hawk to whisk the fish out of the pouch, upon which the pelican does not fly away, but commences fishing again, the fright having probably made him forget he had any thing in his purse.
A fish called mosheba, about the size of a minnow, often skims along the surface for several yards, in order to get out of the way of the canoe.
It uses the pectoral fins, as the flying-fish do, but never makes a clean flight.
