THE SAVAGE WORLD. 79 
The Cow Shark ( Heptanchus indicus ) is found from California to the Cape 
of Good Hope. 
The Eel Shark ( Chlaniydoselachus anguineus ) is found in Japanese waters, 
and though but a few inches in circumference, attains' the length of six feet. 
It is sufficiently like a small specimen of the sea-serpent to have interest in 
connection with what has been submitted in regard to the latter creature. 
The Spiny Shark ( Echinorhinus spinosus ) is a ground shark whose skin is 
covered by tubercles, whose thorn-like prickles leave a mark when handled. 
The Sleeper Shark ( Somniosus microcephalus) is somewhat rare, and most 
frequently found in the Arctic region. It is a long, heavy creature, grayish 
purple with white spottings. It is not a man-eater, but is a deadly enemy of 
the whale, upon which it preys. 
Shark fishing has been described, but it may be as well to add that the 
negroes, in their less highly 
civilized state, are compelled 
to exhibit greater daring than 
the white man. Arming them¬ 
selves with a long, keen knife, 
negroes will boldly dive into 
the water and swim to meet 
the shark, knowing that the 
creature, feeling secure of its 
prey, will await their approach. 
As the shark turns upon its 
side to devour its victim, the 
negro plunges his knife into 
the monster’s belly until he 
who came to eat remains to 
be eaten. 
The Remora is believed 
by credulous sailors to attend 
the shark as a pilot, but nat¬ 
uralists have ascertained that 
it is a more fearful enemy to 
the shark than man himself 
can be. This herring-like creature is about a foot and a half in length, and 
suffers from constitutional weakness of the legs or fins ; it is thus naturally 
inclined to attach itself to some other creature or object from which it requires 
no reciprocity of affection. On top of the head of the remora is an oval 
space, cut up into numerous partitions by many small teeth or bony fila¬ 
ments ; these cavities, therefore, have the power of discs, or suckers, and when 
fastened to an object are but little likely to be removed. t The shark is rarely captured 
without one or more of this fish being found fastened to it—a self-invited and 
evidently unwelcome guest. It is supposed that the remora's preference for the 
companionship of the shark arises from the fact that its presence answers as 
a protection, while the monster’s gluttonous feasts enable the remora to live a 
life of luxurious ease upon the scraps which fall from the shark’s table. This 
arrangement is delightful for the reinoi'a, but somewhat irritating to the shark, 
who, however, evidently submits to the inevitable. The remora takes its name
