Bluebanded Goby

The bluebanded goby (Lythrypnus dalli) is certainly not the most photographed fish in the eastern pacific. Most people go there for big pelagics. Anyways, though very small, these gobies play a very important role in the exchange of nutrients around the rocky reefs of Cedros. Also, they can change their sex within a couple of days to make it easier to reproduce. This and the fact that they constantly hide between sea urchins make them the least vulnerable species of the region.
