Flipper (cricket) Flipper (cricket) The flipper is the name of a particular bowling delivery used in cricket, generally by a leg spin bowler. In essence it is a back spin ball. Squeezed out of the front of the hand with the thumb and first and second fingers, it keeps deceptively low after pitching and can accordingly be very difficult to play. The flipper is comparable to a riseball in fast-pitch softball. By putting backspin on the ball the Magnus effect results in air travelling over the top of the ball quickly and cleanly whilst air travelling under the ball is turbulent. The
Fin and flipper locomotion Fin and flipper locomotion Fin and flipper locomotion occurs mostly in aquatic locomotion, and rarely in terrestrial locomotion. From the three common states of matter — gas, liquid and solid, these appendages are adapted for liquids, mostly fresh or saltwater and used in locomotion, steering and balancing of the body. Locomotion is important in order to escape predators, acquire food, find mates and bury for shelter, nest or food. Aquatic locomotion consists of swimming, whereas terrestrial locomotion encompasses walking, 'crutching', jumping, digging as well as covering. Some animals such as sea turtles and mudskippers use these two environments for different
