The Torrens River at Mt Pleasant is reasonably diverse with more
than 160 aquatic invertebrates collected from this site between
1994 and 2004. Most invertebrates collected from this site can
be found through South Australia.
The aquatic snail Physa acuta can usually be found in
the Torrens River. It is an introduced species, brought to Australia
for use in aquariums and has inadvertently entered the environment.
This snail is pollution tolerant and can be found throughout the
State in most freshwater and brackish streams, except in the Far
North.
