The Blue-dashed rockskipper (Blenniella periophthalmus) has a multitude of small red-orange to red-brown spots scattered all over its body. Its head, surmounted by long supraorbital cirri, is characterized by its protruding and prominent turquoise blue eyes. It has a wide subterminal mouth with a prominent upper lip that allows it to feed on filamentous algae and the small invertebrates they harbor. It can jump from rock to rock in the open air at low tide, hence its English name.
