True to its name, the lumpsucker comes with a literal suction cup on the bottom. Their suction cups evolved from their pelvic fin and allow the fish to anchor itself to its surroundings. It can frequently be found clinging onto eel grass, rocks, or any other objects in its habitat. While the suction cup helps this fish stand out from the crowd, there are other species with similar adaptations–the remora, for example, use suction cups on their heads to attach to sharks, whales, and even ships.
