No, the tails of a whale and a fish are not homologous structures. They have different evolutionary origins and structures, with the whale having a fluke-shaped tail and the fish having a more traditional fin-like tail.
Animals that do not have tails include certain breeds of dogs, such as the Australian Shepherd and the Boxer, as well as certain species of fish, insects, and birds.
Otoliths are small calcium carbonate structures found in the inner ears of fish. They help fish maintain balance and orientation in the water by detecting changes in movement and gravity.
Most fish have bones. Sharks and rays do not have bones but they do have bone-like structures that are made from cartilage.
Cells that move, such as sperm cells, often have tails for movement. That tail is called a flagella and it allow the organism to swim much like a fish. The other mechanism of transport is called silli, which look like little hairs covering the exterior of the organism. These hairs move back and forth to propel the body forward.
Dolphins are very social creatures and will live with any animal under the sea. Although since they eat fish, fish tend to stay away, but any other large sea creatures they will cohabit with.
Dolphin fins and fish tails are not homologous structures; they are examples of convergent evolution. While both serve similar functions in locomotion, dolphin fins are modified forelimbs (homologous to the arms of other mammals), whereas fish tails are derived from the body and are part of the fish's vertebral structure. Thus, their similarities arise from adapting to similar environments rather than from a common evolutionary origin.
Yes, fish fins and whale flippers are considered homologous structures, meaning they share a common evolutionary origin despite their different functions. Both adaptations serve the purpose of propulsion in water, but they have evolved to meet the specific needs of each species. This similarity highlights the concept of evolutionary relationships among vertebrates, showing how different species can adapt similar structures for different environments.
a whale is a fish.
Hi, I just wanted to answer your question. No a sailfish is not a mammal. It is a fish and they breathe by gills, which I'm sure you are aware of. I am an avid whale fan and I've recently learned something that I had not thought about. The mammals of the waters have tails that are horizontal and the fish have tails that are vertical. A lot of people also tend to think that the whale shark is a mammal but in-fact it is not. I hope this has helped you. Sincerely, Tmlragland
try looking here: http://en.wikipedia.org/wiki/WhalesA good deal like big fish, but with one difference. Fish tails are vertical; that is, they stick up and down but are quite narrow from right to left. Whale tails are horizontal, the flukes sticking out to the sides.
shark is to whale as fish is to
No - the Blue Whale is a mammal - not a fish. The largest fish in the ocean is the Whale Shark.
If a bat, a human, an alligator, and a penguin all evolved from a common ancestor, then they should share common anatomical traits. In fact, they do. Compare the forelimbs of the human, the bat, the penguin, and the alligator. Find the humerus, radius, ulna, and carpals in each forelimb. Though the limbs look strikingly different on the outside and though they vary in function, they are very similar in skeletal structure. More significantly, they are derived from the same structures in the embryo. Structures that are embryologically similar, but have different functions, are called homologous structures. Though these animals look different, a comparison of homologous structures indicates that they are quite similar. This suggests that these animals evolved from a common ancestor.by: Lameace[=
they move there tail back and fourth to propel and move but their tails are different then most fish instead of being diagonal like fish they are horizontal. so therefore they move faster then most fish but they seem slower to us.
this is not exactly the answer to you question but a whale is aperently not a fish.
Because it's a whale not a fish
E is to fish as whale is to mammals.
