Issue
The species Johnius sina (Cuvier, 1830) is considered as valid in Ref. 122871.
Environment: milieu / climate zone / depth range / distribution range
Ökologie
seewasser; brackwasser demersal; ozeanodrom (Ref. 51243); tiefenbereich 5 - 50 m (Ref. 122858). Tropical; 26°N - 8°N
Indian Ocean: Pakistan to the Andaman Islands. Records outside this area are probably misidentifications (e.g. of Johnius dorsalis in Africa).
