South American dangerous environmental controversy: combat to the invasive exotic snail Achatina fulica in wildlife v/s conservation of threatened native and endemic land snails


"Public campaigns misguided who seek to control/ eradicate the invasive giant african snail Achatina (Lissachatina) fulica in wildlife promotes the indiscriminate extinction of native snails"

A serious and worrying malacological conflict of conservation is present today in Brazil (and other South American countries): on behalf of public funding carried forward in and attempt to control and eradication of the vast Brazilian territory of exotic invasive African snails Achatina (Lissachatina) fulica (Bowdich, 1822), representative of the Family ACHATINIDAE Swainson, 1840, controversially together large and medium endemic native terrestrial snails, currently in evident situation of threatened extinction, are being indiscriminately decimated for the population as a result of public alarmist campaigns (Agudo-Padrón 2011 a: 42, 2012 - Fig. 1; Aquino 2012 a, b).


                      Campaign for the control of giant African snail




Based in the available technical literature (Simone 2006), we have besides the most traditional families of South American giant and medium native and endemic gastropods, included the Families MEGALOBULIMIDAE Leme, 1973 (genus Megalobulimus Miller, 1878) (Agudo-Padrón 2012 - Fig. 5) and STROPHOCHEILIDAE Thiele, 1926 (genus Strophocheilus Spix, 1827, Anthinus Albers, 1850, Mirinaba Morretes, 1952 * (Agudo-Padrón 2012 - Fig. 2) and Speironepion Bequaert, 1948), involving at least 82 forms each, we have some native forest snails of the Family BULIMULIDAE Tryon, 1896, mainly the Subfamily ORTHALICINAE Albers, 1850, currently native species are just more similar, phenotypically, with the invasive exotic African snail (Aquino 2011 a, Agudo-Padrón 2012 - Fig. 4), that same sum in the territory of Brazil and South America a total of approximately 21 forms taxonomically recognized (more why not well known or studied, virtually all of them have surely included in some degree of danger), classified and included in the genera Orthalicus (10 spec.)(Fig. 6), Sultana (2 spec.) and Corona (9 spec.).

Due to their appearance, eventually species of the genus Thaumastus Albers, 1860 (16 spec.) (Fig. 7), florestal snails representatives of the Subfamily BULIMULINAE Tryon, 1867 (Simone 2006, Colley 2012), may become also involved (Coelho 2005).

Until totally different species of native snails BULIMULINAE, Auris bilabiata (Broderip & Sowerby, 1829) (Fig. 8) by example, of rare beauty and scarcely known scientifically are being destroyed in the frenzy created by collective panic (Aquino 2011 b).

Even little arboreal native species poorly known are being interchanged (Aquino 2011 d), collected and destroyed without further (Agudo-Padrón 2012 - Fig. 3). This disastrous situation should be occurring, simultaneously, in other locations and countries of the continent (Borrero et al. 2009).

The “fatal” potential visual confusion of the invasive African snail with native and endemic species (Agudo-Padrón 2012 - Figs. 4, 5) have been singled out by experts in the literature (Thiengo & Fernandez 2005, Coelho 2005, Colley & Fischer 2009, Pimpão 2010, … among others).

Figure 5.- Native south american snails Megalobulimus cf. elongatus (Bequaert, 1848) (MEGALOBULIMIDAE) and invasive African snails Achatina (Lissachatina) fulica (Bowdich, 1822) … who is who for the laymen ???

The conservation status of native continental molluscs and the parallel occurrence of invasive alien species in the southern region of the country, by example, have been subject to recent extensive discussions and questions (Agudo-Padrón 2009, 2010, 2011 b-g; Agudo-Padrón & Lenhard 2010).


Today, the exotic invasive Achatina (Lissachatina) fulica is present in ALL BRAZILIAN TERRITORY, and the Atlantic Slop of the Southern Cone already settled in the country of Argentina (Gregoric et al. 2011).




Observing the current situation in practice (referential notices and field experience), the public “bad conducted actions” for the control/ eradication of Achatina (Lissachatina) fulica in Brazil (Agudo 2006; Aquino 2011 c, e), officially opened in 2003 with the “prohibition” of the species in the country (Aquino 2012 b) – initially introduced in 1988 through the Paraná State, PR, Southern region (Globo 1992, 1994; Teles & Fontes 2000; Thiengo et al. 2007; Colley & Fischer 2009), 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 molluscs 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.
