CHAP. 72. (48.)—VENOMOUS SEA-ANIMALS.
Nor yet are dire and venomous substances found wanting in the
sea: such, for instance, as the sea-hare[1] of the Indian seas,
which is even poisonous by the very touch, and immediately
produces vomiting and disarrangement of the stomach. In
our seas it has the appearance of a shapeless mass, and only
resembles the hare in colour; in India it resembles it in its
larger size, and in its hair, which is only somewhat coarser:
there it is never taken alive. An equally deadly animal is the
sea-spider,[2] which is especially dangerous for a sting which it
has on the back: but there is nothing that is more to be dreaded
than the sting which protrudes from the tail of the trygon,[3]
by our people known as the pastinaca, a weapon five inches in
length. Fixing this in the root of a tree, the fish is able to
kill it; it can pierce armour too, just as though with an arrow,
and to the strength of iron it adds all the corrosive qualities of
poison.
1. It is mentioned again in B. xxiii. c. 3. Cuvier says, that the sea-hare of the ancients is the mollusc to which Linnæus has 'injudiciously
given the name of aplysia, which Pliny gives to certain of the sponge
genus, and to which nomenclature of Linnæus the modern naturalists have
assented. (See N. 51, p. 456.) Its tentacles and its muzzle, he says, resemble
the muzzle and ears of the hare, closely enough to have caused this appellation.
As its smell is disagreeable, and its figure repulsive, a multitude of marvellous, and indeed fatal qualities, he says, have been ascribed to this animal,
which fishermen still speak of, but which, nevertheless, are not confirmed by
actual experience. The only true fact that can be alleged against it is,
that it secretes from an organ, situate in its body, a kind of acrid liquid.
As to the Indian sea-hare, the body of which was covered with hair, Cuvier
professes himself quite at a loss to know what it might be; but he thinks
that this name must have been given to some tetrodon, which may have
received the name from the cleft in the jaw and the skin, bristling with fine
and minute spines. The sailors, he says, attribute to the tetrodon certain
venomous properties.
2. Cuvier says, that there is reason to believe that this is the same as
the vive of the French (probably our weever), the Trachinus draco of
Linnæus. This creature, with the spiny projections of its first dorsal fin,
is able to inflict wounds that are extremely difficult to cure; not because
they are venomous in any degree, but because the extremities being very
minute, sharp, and pointed, penetrate deep into the flesh. See c. 43 of
this Book.
3. Or sting-ray, mentioned in c 40 and c. 67 of this Book; so called
from the Greek trugw\n. Cuvier says, that this sting, or spine, is sharp,
like a saw; and that when it has penetrated the flesh, it cannot be got out
without enlarging the wound. This it is, and not its fancied poisonous
qualities, that renders its wound so dangerous; and as for its action upon
trees and iron, they are entirely fabulous.
