Range and Identity
The inventory retains Ophieleotris aporos, while the checked source resolves to Giuris margaritaceus under a broad regional treatment. Original locality and identification remain important when comparing regional gudgeons. The source context is preserved rather than silently changing the inventory identity or assigning unrelated snakehead records to it.
Habitat and Behavior
Habitats include rivers, swamps, coastal streams and floodplains, often over mud and near dense plants or undercut banks. Freshwater adults and a marine pelagic larval stage are described, while estuarine records also occur. These life-stage differences should remain visible instead of imposing one salinity on every observation.
Food and Life History
The upper reference is 31.2 centimeters total length. Aquatic insects and nymphs dominate the listed foods, with smaller amounts of plants and crustaceans. A small compiled mass is not established as a secure species maximum.
Field Note
Record life stage and whether the site is freshwater or tidal. Those details help interpret a gudgeon observation within its river-to-coast setting.
