Tag: Nakedhead Shrimpgoby (Amblyeleotris Gymnocephala)

The Nakedhead Shrimpgoby (Amblyeleotris Gymnocephala) ranks among the largest and most common species of Goby found in local waters.

The most distinguishing feature of this species is the dark horizontal line from behind the eye. It has 5 diffuse, vertical brown bars along the body, with dark marks between the bars.

Also noticeable are the faint blue-ish margin along the dorsal fin and blue-ish and purple double margin on the anal fin.

In local waters, this species appears to be more approachable than many of its relatives and it can often be seen straying relatively far from the burrow it shares with one or more Alpheid Shrimps.

Note: for a long time i had this listed as the Giant Shrimpgoby (Amblyeleotris Fontanesii) due to it being slightly larger than other local species and also because its markings are very similar to those of the Giant Shrimpgoby.

Only the fact that i have yet to find a photo of a Giant Shrimpgoby with this characteristic dark horizontal line behind the eye has made me stick with the opinion that this is in fact, the Nakedhead Shrimpgoby.

If anyone can offer any advice on the correct identification of this species, i would be most grateful.
