All the sources I've read say slow, but I've seen some that swim quite fast... it might depend on the fish, but generally slow.
a clown fish is fast
think its slow...
Koi are generally slow swimmers unless they are being preyed upon or are ill. If your koi is swimming fast or erratically, check for signs of illness or injury.
It has a better chance of escaping from predators.
Lantern fish and angler fish differ in physical characteristics and hunting strategies. Lantern fish are small and have bioluminescent organs for camouflage and communication, while angler fish are larger and have a bioluminescent lure to attract prey. Lantern fish are fast swimmers and hunt in schools, while angler fish are slow and use their lure to ambush prey.
Ocean sunfish can go fast as 3.2km(two miles) per hours. Its REALLY slow. Slow as snail. Its largest bony fish but really slow and poor diet.
Pipefish do not have large fins, making them slow swimmers. Pipefish have prehensile tails for grabbing and holding onto plants.
I'm not sure what exactly you want to know about the muscle fibers and I'm no expert, but here is how I understand it. Swimmers tend to exercise fast twitch and slow twitch muscles in they're workouts. The fast twitch are engaged during sprint sets and the slow twitch are engaged during aerobic sets. So all swimmers have well developed fast and slow twitch muscles. Good sprinters will probably have 60 to 70 percent fast-twitch muscle, while good long distance swimmers may have around a 50/50 split. Whether or not weightlifters have fast or slow twitch muscles depends on the type of workout they do. Sets consisting of fast, explosive lifts will build more fast twitch muscle fibers, and longer, slower sets will build slow twitch muscle fibers. That's one reason why plyometric workouts are effective for any athlete who needs flat-out speed; the fast-twitch muscles are engaged and enlarged through fast, explosive training. Besides that, a muscle fiber is a muscle fiber as far as I know. To be a great swimmer you have to incorporate a weight regimen into your training plan, so the swimmers and weightlifters will be similarly built, outside of the fast/slow twitch differences. I hope that helps. And if anyone else out there has something to add, I'd like to know more myself.
No, starfish walk along the bottom and on rocks either on tube feet, or in serpent stars, they pull themselves along with the arms.
a fish is fast and breathes in water and a turtel is slow and green
Stingrays are generally considered to be slow swimmers, capable of moving at a moderate pace while gliding through the water. They are not known for their speed or agility compared to other marine animals like dolphins or sharks.
not usually due to how cold it is the deeper you go. the movement of deep sea fish are usually slow and intricate.
