The ability to regenerate neural tissue is widespread among numerous animal phyla, such as Ctenophora, Cnidaria, Playhelminthes, Annelida, and Nemertea
, to name a few (Alvarado, 2000; Brown et al., 2009; Bely and Nyberg, 2010; Somorjai et al., 2012; Giangrande and Licciano, 2014).

According to Rocha (2002), only 30% of the freshwater invertebrate diversity is presently known and some taxon as Porifera, Cnidaria, Platyhelminthes, Nemertea
, Nematoda, Nematomorpha, Bryozoa, Annelida and several insect groups need specialists, collections and/or minimum updated information on identification, distribution and autoecology.

All organisms were counted after identification to species level, with the exception of Ophiuroidea, Turbellaria, Nemertea
and Polychaeta which were identified to higher taxonomic levels.
