It doesn't need fins to move forwards, but fins are used to control rolling from side to side
Stabilising fins prevent a side to side rolling motion.
The fins help steer the submarine; making it be able to turn left or right.
fairwater planes
They just move with waves and float so they don't need huge fins.
Yes. Wobbegongs are sharks, and need to be able to move freely in the water, so they do have fins. They have short caudal fins and much broader pectoral and pelvic fins.
what does the term stabilizing fin mean
Well, darling, submarines need fins to help with stability and control underwater. Those fins act like the submarine's rudder, helping it steer smoothly through the depths. So, next time you see a submarine cruising along, just remember it's those fins keeping it on course.
Fins are used by squids to move at low speeds. Their siphon is used when they need to move quickly.
fins
ventral fins.
They are actually called "planes" on a submarine and allow it to maneuver underwater. Horizontal "planes" allow the submarine to go up/down, vertical "planes" allow the submarine to go left/right.
they move there fins and muscles to move in the water!
