The fins of many fish, including gurnards and sea-robins, taste potential food using taste buds located on their tips.

"The long, slender fins of many species [of fish] bear taste buds at their tips, enabling them to taste a potential food just by touching it. The pectoral fins of gurnards (Trigla spp.) and sea-robins (Prionotus spp.), for example, include several separate, fingerlike sections, which the fish uses not just for 'walking' along the sea bottom, but also for tasting -- by touch -- any potential food. Only if satisfied with the taste signals will the fish eat the object." (Shuker 2001:32-33)
