Physical Features
Adult fish can grow up to two inches in length, with the striking pointed dorsal fin becoming more raised and pronounced in adulthood. This elongated fin is the most obvious distinguishing feature between the black-ray goby and its close cousin, the yellow snout goby (S. Xanthorhinica). The fish are beautifully coloured with four diagonal brown stripes across a white body, and a distinctive yellow head. See accompanying photograph for reference.
It is almost impossible for anybody less than a specialised expert in the specific field of these types of fish to discern differences between males and females of the species.
