Location Habitat
The Gurnard uses the front rays of this pectoral fins to scratch in the sand for invertebrates. When the hapless invertebrate pops out of the sand, the Gurnard pounces on it. I believe that the wide pectorals funnel the prey forward towards his mouth. These are found on sandy bottoms and are not at all common.
