The coastal plain of the State of Santa Catarina/ SC
(Lindner 2014: 11), 25°57’41’’S - 29°23’55’’S, having
a length of 580 km of meandering and diverse
mainland and island coast (Figure 1), is located on a
large "transition zone", still subject to technical
discussions because of the complexity of its nuances
and dynamic oceanographic, result of "convergence"
between two major ocean currents: “Brazil”, hot to
the North, and “Falkland or Malvinas”, cold to the
South , apparently the section of the coast of Brazil
between “Rio de Janeiro - RJ” and “Santa Catarina -
SC” regions functions as an "ecological filter",
preventing the dispersal of species, they are
thermophilic - typical of the marine zoogeographical
Caribbean Province - or cryophilic - typical of the
Patagonian marine zoogeographical Province
(Agudo-Padrón 2012, 2014 b).

This condition determines in the local environment a
sensitive, diverse and heterogeneous biotic faunal
composition, whose characteristics are to have a high
potential on the contemporary practice of marine
malacoculture (Agudo-Padrón & Bleicker 2009: 5) as
well as incentive for the development of accurate
research on the marine biotic diversity occurring in it
(Agudo-Padrón 2012). But, paradoxically, regional
literature of recent production unexpectedly speculates
that, by example, only about “550 species” occur on
the coast of Santa Catarina State/ SC (Agudo-Padrón
2014 b: 36), fact that only reflects the profound
regional collective unfamiliarity that still prevails
around the subject, when earlier contributions already
published outweigh said numerical estimate
(Agudo-Padrón et al
