Many new things were learned during the succeeding months of studying this strange animal, but chief among them were the facts that the gray whale differs so strongly from all others that it must be placed in a family of its own; also that it is the most primitive of all existing large cetaceans and is virtually a living fossil.
CHAPTER XVI
HOW KILLERS TEAR OUT A GRAY WHALE’S TONGUE
The gray whales, as well as other large cetaceans, have only two enemies—man and one of their own kind, the orca or killer whale. Although twice the size of the killers and correspondingly strong, when one of the orcas appears the devilfish become terrified and either wildly dash for shore or turn belly up at the surface, with fins outspread, paralyzed by fright.
A few days after my arrival at Ulsan, three gray whales were brought to the station, one of which had half the tongue torn away; teeth marks clearly showed in the remaining portion and Captain Hurum, who had killed the animals, told me that it was the work of killers.
There were seven gray whales in the school, he said, and shortly after he began to hunt them fifteen killers appeared. The whales became terrified at once and he had no difficulty in killing three of the seven. When the orcas gathered the whales turned belly up and made not the slightest attempt to get away. A killer would put its snout against the closed lips of the devilfish and endeavor to force the mouth open and its own head inside. This extraordinary method of attack was corroborated by Captain Johnson, who had been hunting the same school of gray whales, and, moreover, by all the whalemen at the station, who had witnessed it upon many other occasions.
Cutting through the body of a gray whale. The thick layer of blubber surrounding the red meat is well shown.
Of thirty-five gray whales which I examined especially, seven had the tongues eaten to a greater or less extent and one had several large, semicircular bites in the left lower lip. The killers do not confine their attention entirely to the tongue for almost every whale which was brought in had the tips and posterior edges of the fins and flukes more or less torn; in several specimens fresh teeth marks were plainly visible where the fin had been shredded as the whale drew it out of the orca’s mouth.
Although none of the gray whales exhibited teeth marks on other parts of the body, undoubtedly some of them are killed by the orcas. A female killer which was brought in had several pieces of flesh in its stomach, besides a strip of whalebone three inches long. I could not positively identify the latter but believe it to have been from a small devilfish. A male killer was taken at the same time by Captain Hurum, who told me that in the animal’s death flurry it had thrown up two great chunks of flesh.
Captain Melsom brought a gray whale to the station one day and I found that the tongue was almost gone. He said he had passed a school of killers in the morning and later, after steaming about fifteen miles, had killed the devilfish. A short time afterward, a long distance away, he saw the fins of a school of killers which were coming at full speed straight for the ship. They circled about the vessel and one of them forced open the mouth of the dead whale to get at the tongue. Captain Melsom fired at the killer with his Krag rifle and when struck the animal lashed out with its flukes, smashing the ship’s rail, and then disappeared.
