A few more Rockling pics from my personal collection.
5 Bearded Rockling.
2 pairs of beards above the mouth. Usually pale brown in colour as live over sand.
Shore Rockling.
Only 1 pair of beards above the mouth. Darker borwn in colour. Found in rocky areas.
3 Bearded Rockling.
Pink rather than brown with blotches of brown on the back and as the name suggests, only 3 beards.
