Gudgeon and Sleeper Gobies


 

GUDGEON

 

Gudgeon (Genus Gobiomorphus) are small, benthic (lives in the lowest level of water) fish with large, rounded fins and two dorsal fins. Many have an amphidromous lifecycle: the eggs are laid in fresh water, but the fry are dispersed to sea soon after hatching, and grow there for several months before returning to fresh water. Being small and benthic means that they are unlikely to be seen. Being amphidromous also means that they will not be common in the CNM region.

 

Of the fives species of Gudgeon found in the region, most are rare and so any sightings are important.

This is a gudgeon of some type, probably Firetail or Western Carp. The presence of two dorsal fins means this is not a Gambusia.
