Roosevelt, Theodore, 1858-1919

"Through the Brazilian Wilderness"

Doctor Brazil told me that he had
conducted many experiments with this interesting snake. It is not very
common, and prefers wet places in which to live. It lays eggs, and the
female remains coiled above the eggs, the object being apparently not
to warm them, but to prevent too great evaporation. It will not eat
when moulting, nor in cold weather. Otherwise it will eat a small
snake every five or six days, or a big one every fortnight.
There is the widest difference, both among poisonous and non-poisonous
snakes, not alone in nervousness and irascibility but also in ability
to accustom themselves to out-of-the-way surroundings. Many species of
non-poisonous snakes which are entirely harmless, to man or to any
other animal except their small prey, are nevertheless very vicious
and truculent, striking right and left and biting freely on the
smallest provocation--this is the case with the species of which the
doctor had previously placed a specimen on the table. Moreover, many
snakes, some entirely harmless and some vicious ones, are so nervous
and uneasy that it is with the greatest difficulty they can be induced
to eat in captivity, and the slightest disturbance or interference
will prevent their eating. There are other snakes, however, of which
the mussurama is perhaps the best example, which are very good
captives, and at the same time very fearless, showing a complete
indifference not only to being observed but to being handled when they
are feeding.
