| Re: Blennies vs. Gobies (look the same to me)
These two species are superficially, very similar. Gobies generally have fused pectoral fins that form a cup that they use to prop themselves up on and to grasp vertical walls. Blennies generally have a continuous, long dorsal fin that runs the length of the body to the tail. Blennies also have projections called cirri, on their head, that the gobies lack. Some of the gobies are cleaner fish.
What you describe is a Yellow Watchman goby. |
