A third long, undulating shape issued from the hole in the rock, felt about his body, lashed round his ribs like a cord, and fixed itself there. There was sufficient light for Gilliatt to see the repulsive forms which had entangled themselves about him. A fourth ligature, but this one swift as an arrow, darted towards his stomach.
These living things crept and glided about him; he felt the points of pressure, like sucking mouths, change their places from time to time.
Suddenly a large, round, flattened, glutinous mass shot from beneath the crevice. It was the centre! The thongs were attached to it like spokes to the nave of a wheel. In the middle of this slimy mass appeared two eyes. The eyes were fixed on Gilliatt.
He recognised the devil-fish.
Gilliatt had but one resource--his knife.
He knew that these frightful monsters are vulnerable in only one point--the head. Standing half naked in the water, his body lashed by the foul antennae of the devil-fish, Gilliatt looked at the devil-fish and the devilfish looked at Gilliatt.
With the devil-fish, as with a furious bull, there is a certain moment in the conflict which must be seized. It is the instant when the bull lowers its neck; it is the instant when the devil-fish advances its head. The movement is rapid. He who loses that moment is destroyed.
Suddenly it loosened another antenna from the rock, and darting it at him, seized him by the left arm. At the same moment it advanced its head.
Rapid as was this movement, Gilliatt, by a gigantic effort, plunged the blade of his knife into the flat, slimy substance, and with a movement like the flourish of a whip, described a circle round the eyes and wrenched off the head as a man would draw a tooth.
The four hundred suckers dropped at once from the man and the rock. The mass sank to the bottom of the water.
