Habitat
FishBase describes this species primarily from muddy estuarine bottoms. It also occurs in freshwater and in waters saltier than the open sea. That wide salinity tolerance helps explain why records can come from quite different coastal environments within its range.

Identification and records
The scientific name Guavina guavina is the most useful link between records carrying different regional common names. The species has eight dorsal spines, ten dorsal soft rays and nine or ten soft rays in the anal fin. These are technical identification characters for an examined specimen; a distant view of an estuary fish is unlikely to reveal them. The available summary is strongest on habitat and distribution and gives little detail about its reproduction.
