Rainfordia opercularis VIDEO from Blue Harbor, Japan


Raindfordia opercularis at Blue Harbor

Rainfordia opercuarlis is endemic to Australia and is rarely seen in nature and virtually never seen in captivity due to its cryptic lifestyle.  Similar to its cousins in the genus Liopropoma, this monospecific species dwells in caves and narrow ledges of sheltered, inner reefs.  Its unique depressed,flattened head – with wide mouth and eyes set close to the mouth – has likely evolved for this particular habitat. Not much is known about R.opercularis, so hopefully this captive specimen will give us more insight into its behavior.  It’s a truly fascinating fish!
