Our next unidentified fish comes to us all the way from Japan. Please take a careful look at the photos and try and let us know what species this is in the comments below... "I found a few of these gobies, or blennies, or jawfish in the tidepools of northern Japan. I am not sure what kind of fish it is, but I would like to find out what it is, how big they get, what it eats, and what ever kind of things might be known about it. The ones pictured are about 3/4 of an inch to one inch long. I believe I have seen them about four to six inches in length."
