Today, the original floater is made in seven different sizes and fourteen different colors. It can be found in many anglers' tackle boxes, and is the best-selling lure Rapala makes, and possibly best-selling in the world. The lure, when retrieved, swims with an action that mimics that of a wounded baitfish.

Fish in the order Gymnotiformes possess electric organs along the length of their bodies and swim by undulating an elongated anal fin while keeping the body still, presumably so as not to disturb the electric field that they generate. Many fish swim using combined behavior of their two pectoral fins or both their anal and dorsal fins.
Passive integrated transponder (PIT) tags consist of an integrated circuit chip, capacitor, and antenna coil encased in glass. They have been used since the mid 1980s with scientists studying fish movements. Since then, PIT tags have been used to study the movement of amphibians, reptiles, birds, and invertebrates. [20]
Different fish swim by undulating different parts of their bodies. Eel-shaped fish undulate their entire body in rhythmic sequences. Streamlined fish, such as salmon, undulate the caudal portions of their bodies. Some fish, such as sharks, use stiff, strong fins to create dynamic lift and propel themselves.
