Then he discovered his companion. From a crevice near his left elbow two unspeakably evil eyes peered out. Below them was an open mouth set with rows of inch-long, incurved teeth like those of a boa constrictor. Back of the mouth were gill openings. But Hal knew that this was no fish. No fish in the seven seas could have such terrible eyes. Besides, the dark green skin was nothing like the scaly hide of a fish. Hal knew that he was looking straight into the eyes of a giant moray eel. Being a good animal-collector, the first thing he thought of was not his own safety but the fact that this was one of the specimens Dr Blake most wanted to obtain. Of course, to be of any use in an aquarium, it must be captured alive. He had no noose, no net, no narcotic drug. He had nothing but his two hands. And just outside the door waited a tiger shark. But perhaps he could use the moray to get rid of the shark! The giant moray is the shark’s most dreaded enemy. Even though the shark may be three times as large, it is at the mercy of the moray which can wheel and turn and twist so fast that the heavy fish cannot succeed in locking its jaws upon this wriggle of green lightning.
