Shadow goby
Acentrogobius nebulosus
Family Gobiidae
updated Oct 2016
Where seen? This little goby is commonly seen on many of our shores including mangroves, muddy bottoms near reefs, sandy pools and among coral rubble. On some shores, almost every pool has one! Its previous name was Yongeichthys nebulosus.

Features: Up to about 18cm, those seen from 4-6cm. It has large eyes and three large dark brown blotches on the sides of the body (not easily seen from the top). It seems to be able to withstand heat and several are commonly seen in shallow pools left behind at low tide.

It is poisonous to eat as it contains tetrodotoxin (the same toxin found in pufferfishes) in its flesh and internal organs. In some places, it is called the Poisonous goby.
