Vale la pena remarcar que actualmente en la zona de Salto se registran dos Chelidae pertenecientes a las especies Phrynops hilarii e Hydromedusa tectifera y se carece de registros de Testudinidae (FREIUERG, 1977; CEI, 1986).

hydromedusa Blackfordia virginica (Cnidaria: Black-fordiidae) in southern Brazil, with comments on taxonomy and distribution of the genus Blackfordia.
These new methods and technologies have allowed scientists to resolve the life cycles of many organisms whose hydroid and
hydromedusa stages were previously thought to be separate species, and to conduct a variety of experimental studies in the laboratory.
The most transparent tissues (at 480 nm) were
hydromedusa mesoglea (66%), followed by Cystosoma (42%), ctenophore mesoglea (41%), siphonophore mesoglea (39%), pelagic tunicares (excluding Pyrosoma) (33%), Sagitta (24%), and the translucent portions of the hydromedusae and ctenophores (24%).
