Confirmed observations

‘The species holotype originates from the Bay of Warships in the Douala region of Cameroon (Kükenthal, 1892). Recently, a sighting and bycatch (landed) were documented from the far south of Cameroon close to Equatorial Guinea (Ayissi et al., 2014)’. A survey in 2016 did not yield any new sightings of the species (Van Waerebeek et al 2017).

Threats and trends

No abundance estimates are available for this population. Bycaught specimens of Sousa teuszii, were recorded from Campo, southern Cameroon in 2012, and a fish landing site near Kribi in 2014 (Van Waerebeek et al. 2017).
