Project Description

The northern clingfish (Gobiesox maeandricus) has modified pelvic fins that hold onto rocks and kelp fronds like a suction cup, allowing this small fish to hunker down and ride out rough waves pounding the shoreline.  It’s interesting that the northern clingfish can also hold moisture in this suction cup, so if hiding under a rock in a tide pool that dries up it can continue to breathe until the next high tide returns with cool oxygen rich water.   The northern clingfish can grow to 6.5 inches (16.5 cm) in length, with a range from southern Alaska to northern Mexico.
