“prohibition” of the species in the country – initially introduced in 1988 through the Paraná State, PR, Southern
region, and a second time at the beginning of the 1990s, through the “Santos” Port in “Praia Grande”, São Paulo
State, SP, Southeastern region (Armellini & Santana, s/d) – and consequent “premature release” into the
environment of animals in livestock management regime (continental malacoculture or “escargot” farming) for
fear of possible law sanctions, today are becoming an important element much more damaging to our suffered
native and endemic terrestrial mollusks itself occurrence in wildlife of the giant African invasive snail,
unconsciously accelerating the extinction process of the first, by which they urgently need to be re-evaluated and
re-oriented by the corresponding authorities.

Encouraged by public campaigns “bad conducted”, the population “unprepared” capture and destroys indiscriminately
every snail that is one its way (upper). Following growth of the exotic
Achatina
(
Lissachatina

: as the size, native snail species
can come easily be confused with these (below).
