An organ of a fish, consisting of a membrane supported by rays, or little bony or cartilaginous ossicles, and serving to balance and propel it in the water.
A membranous, finlike, swimming organ, as in pteropod and heteropod mollusks.
A membranous appendage extending from the body of a fish or other aquatic animal, used for propelling, steering, or balancing the body in the water
The fin shaped things on the bottom of a surfboard. Most boards now have 3 fins and are also referred to as thrusters. In the past though boards had 2 fins (twin-fins) and before that only a single fin. Their purpose is to create latteral resistance or in other words stop you sliding sideways
the part of a dolphin and whale that helps them swim
A flattened appendage on various parts of the body of many aquatic vertebrates and some invertebrates, including fish and ceteaceans, for propelling, steering, and balancing ( dorsal fin; anal fin).
a shoe for swimming; the paddle-like front is an aid in swimming (especially underwater)
a stabilizer that resembles the fins of a fish
organ of locomotion and balance in fishes and some other aquatic animals
propel oneself through the water in a finning motion
show the fins above the water while swimming; "The sharks were finning near the surface"
A fan-like body part in ray-finned fish. It has spines covered with a thin skin. The fish uses it to move.
Body parts of fish used to swim and steer. Dorsal fins are on the back, caudal fins are on the tail, anal fins are underneath towards the back, and pectoral fins are underneath towards the front. Fin size, shape, and color can be used to identify different fish species.
Rudderlike device(s) used beneath a surfboard to assist control, direction and drive. Many different fin shapes are possible, but most are designed to resemble a dolphin's dorsal fin. Today fins are mostly used in groups of three-two ahead, one behind-a configuration known as a Thruster (see Thruster). They're also used, less frequently, in pairs or singles. * see illustration
Rudder like device(s) used beneath a surfboard to assist control, direction and drive. Many different fin shapes are possible, but most resemble a dolphins dorsal fin. They are mostly used in sets of three (two ahead, one behind) known as a thruster set up. Many longboards use just one large fin ( single fin) with designs like fishtails using two, there have also been designs that use up to six.
A fin is a part of aquatic animals that helps them swim, steer, and balance in the water. Many whales have dorsal fins.
A fin is a surface used to produce lift and thrust or to steer while traveling in water, air, or other fluid media. The first use of the word was for the limbs of fish, but has been extended to include other animal limbs and man made devices.
