). Dozens of individuals were observed swimming in the water column. There is organic material composed by plant fragments that are flushed in from the outside by water during rainy periods. The water table appears to vary over the year so the configuration of the pond level may be variable depending on the season. Other fractures were observed in the region, although apparently not connected with the water table. Although the only possible habitat for this species appears to be Andorinhas Cave, it is quite likely that the distribution of the species is more extensive, comprising part of the water table in the area.
