Are vertical or horizontal tails better?
Fish inherited that movement, for which a vertical tail is best. Their distant land mammal descendants evolved to run with limbs underneath: an unstable gait allowing rapid direction changes. To extend the stride, their spine flexes up-and-down. Marine mammals kept this movement, for which a horizontal tail is best.
Are shark tails vertical or horizontal?
It seems to be a common theme that marine mammals have their tail fins horizontal to the plane of the water while sharks and other fish seem to have a vertical tail fin.
What fish has a truncated tail?
Many members of the family of sea basses and groupers such as California’s giant sea bass (also known as the black sea bass), the Caribbean’s yellowmouth grouper and the gigantic grouper are equipped with a truncate-to-rounded tail fin.
Why do sharks have vertical fins?
These fins work like the vertical stabilizer wing on an airplane. They help the shark keep its balance as it moves through the water and they can be moved from side to side to turn the shark left and right. This fin arrangement gives sharks amazing maneuverability.
Are there any fish with horizontal tails?
Unlike fish, whales and dolphins evolved from four-legged animals with limbs underneath their bodies, their backbones naturally bend up and down and not side to side. It is also why their tail fins are horizontal and not vertical like those of fish. The tail fin, or fluke, is used for propulsion through the water.
Why do fish swim side to side?
Fish with streamlined bodies and a stiff, crescent-shaped caudal fin or tail, tend to move rapidly through the water by swishing their tail from side to side. This action propels the fish much like sculling (rowing a boat with an oar) propels a boat.
Are there fish with horizontal tails?
so they basically just rotate 90 degrees and their caudal fin (together with the rest of their body) will be oriented horizontally. The only other ones I can think of that have a horizontal tail are mammals like whales and dolphins, but they are not fish.
What does a forked caudal fin mean?
Caudal Fin The shape corresponds to the cruising speed of the fish. Fish that spend most of their time cruising and searching for prey have forked caudal fins. A forked tail has less drag. When a fish locates a potential meal, a quick flick of the tail will give a sudden burst of speed.
Is a whale faster than a shark?
What is this? Size and speed advantage – When it comes to size and speed, killer whales can grow to be twice as large as a great white shark and can reach speeds of 50% – 100% faster than the great white for short bursts allowing them to surprise and quickly reach their prey before it can escape.
What does a dolphin tail do?
The dolphin’s tail is called its flukes (each half is a fluke). The dolphin uses its flukes for swimming and its flippers for steering. Most dolphins have a boneless dorsal fin in the middle of their back that works somewhat like the rudder on a boat. Like the flukes, the dorsal fin does not contain any bones.
What’s the difference between horizontal and vertical?
A vertical line is any line parallel to the vertical direction. A horizontal line is any line normal to a vertical line. Vertical lines do not cross each other.
Why does a fish have a vertical tail?
Fish muscles move the spine from side to side, which is why a vertical fin is necessary to propel the body forward in a slithering motion. A horizontal fin would not work very well, though I have read somewhere that there are a few rare fish with horizontal tails.
Why do cetaceans have horizontal tail fins?
Cetaceans and other sea mammals (e.g.: Sea lions, Seals, Sea Elephants, Manatees, et cetera), are, obviously, mammals, therefore they descend from species that lived on land. Their tails are horizontal because of the posterior limbs of their land ancestors (legs), they evolved into tail fins.
What kind of fish has vertical stripes on its body?
Smallmouth bass may have vertical stripes on the side of the body. The end of the jaw typically reaches to the center of the eye. The smallie is one of the best freshwater game fish sought after by anglers. They are known for an amazing fight from beginning]
What kind of Fins does a ray finned fish have?
Pectoral and pelvic fins have articulations resembling those of tetrapod limbs. These fins evolved into legs of the first tetrapod land vertebrates, amphibians. They also possess two dorsal fins with separate bases, as opposed to the single dorsal fin of ray-finned fish. The coelacanth is a lobe-finned fish which is still extant.
