Q2) How is a whale similar to a fish in adaption to life in water? … The tail and fins of the whale are like other fishes which help them a lot to swim in an efficient way in the underwater environment.
How are whale and fish similar?
Though whales are mammals and fish are not, they are similar in some ways. Both have fins and a tail, which helps them swim and stay upright in the water. But these similarities are in appearance only. … Fish, on the other hand, have vertical tails, which move from side to side.
How is a whale different from a fish even though both are aquatic animals?
Fishes and whales are both vertebrates, and live in similar aquatic environments. Except for a few species, whales only live in the ocean water, whereas fishes inhabit in both fresh and salt water. … Being mammals, whales are warm-blooded, and are required to maintain a constant warm body temperature.
What are the adaptations of a fish to live in water?
- Fish have gills that allow them to “breathe” oxygen in water. …
- Fish have a stream-lined body. …
- Most fish have several fins for swimming. …
- Fish have a system of muscles for movement. …
- Most fish have a swim bladder.
What are the difference between fish and whales?
Whales are warm blooded. Fish are cold blooded. Whales breathe air through lungs. Fish use gills to extract air from water.

Do whales and fish have common ancestors?
The common ancestor of whales and fish possessed genes for fins. Technically, this statement is true. At least some of the fins of whales and fish are even distantly homologous, even though the lineages leading to tetrapods (including whales) and to ray-finned fishes diverged quite early in their evolutionary history.
What is adaptation What are adaptive characteristics of fishes?
the four adaptive features of fish is as follows- they contain gills to breathe in water without any problem, they have a streamed line body which helps them to swim freely in water, they are cold blooded which helps them to survive in the cold water, they have several fins which help them to swim.What are two features that helps fishes to survive in aquatic area?
- Streamlined, spindle-shaped body which is covered with scales. …
- Skeleton is made up of thin bones with the flexible backbone.
- Flat fins and tails to help them swim, change direction and to keep the body balanced.
Subjected to the same environmental forces, fish, aquatic reptiles and aquatic mammals independently evolved similar shapes because a streamlined body is the most efficient way of moving through the dense medium of water.
Article first time published onWhich animal is most closely related to whales?
Hippos spend lots of time in the water and now it turns out (or researchers argue), they are the closest living relative to whales.
Why did whales evolve to live in water?
The theory is that some land-living ungulates favoured munching on plants at the water’s edge which had the added advantage of allowing them to easily hide from danger in shallow water. Over time their descendants spent more and more time in the water and their bodies became adapted for swimming.
Are whales fishes?
Mammals all are warm-blooded animals, they breathe air, have hair, and moms feed their babies milk from mammary glands. Whales actually do all of these things! Whales are warm blooded, which means they keep a high body temperature that does not change in the cold water. … So whales are indeed mammals and not fish!
Why do whales look like fish?
Whales, dolphins, and porpoises are mammals that look like big fish. They have flippers instead of front limbs and they have no back limbs at all. They also have a tail that is flattened to form two flaps called flukes. The tail flaps up and down unlike fish, whose tails flap from side to side.
What adaptations enable a whale to conserve oxygen while underwater?
These adaptations enable a baleen whale to conserve oxygen while underwater. Baleen whales, like other mammals, have a slower heart rate while diving. When diving, blood is shunted away from tissues tolerant of low oxygen levels toward the heart, lungs, and brain, where oxygen is needed most.
How does adaptation tie into aquatic science?
An adaptation is a behavioral, structural, or physiological trait that increases a species’ chance of survival in a specific environment. Every living thing has adapted to fit with where it lives. That’s what it takes for life to survive. Aquatic organisms live in water and have adaptations to do so.
How is a fish adapted to live in water for Class 6?
The streamlined body shape helps the fish to move through the water easily (because such a shape offers least resistance to motion). (2) The fish has special organs called “gills” which-help it to absorb oxygen-dissolved in water for breathing. A fish can live in water only because it is adapted to breathe in water.
What are some of the adaptations that help marine fishes live and reproduce in the ocean?
- Gills take oxygen out of the water so that the fish can “breathe” underwater. …
- Most fish have a streamlined shape as well as a tail and fins to help them move easily and quickly through the water.
How do we know that sharks and whales similarities are because of convergent evolution?
When two groups of organisms independently evolve similar adaptations, it’s called convergent evolution. Sharks and whales both have streamlined bodies and tail flukes. How do we know that these similarities are because of convergent evolution? Hint: Whales are tetrapods.
How is the whale more like a human than a fish?
Whales are more closely related to humans than to fish She serves as the executive director of the Blue Ocean Society for Marine Conservation. Whales are a member of the cetacean family, and as such, despite being wholly water-resident, whales are mammals, not fish. … All cetaceans, toothed or baleen, are mammals.
What do whales and humans have in common?
“Both humans and killer whales have big brains and are able to master complex behaviors, and perhaps, most importantly, innovate new behaviors that help them adapt to different environments and to hunt different prey often using quite specialized hunting behavior,” lead author Andrew Foote told Discovery News.
Are whales more closely related to sharks or hippopotamuses?
In fact, hippopotamus are actually whales’ closest “cousins”, and they’re much more closely related than you might guess. Based on their fossil record, scientists have determined that whales are related to land dwelling mammals that lived on Earth between 52 – 47 million years ago.
In which ways are whales and hippos similar?
One notable similarity between the two groups is minimal hair — both hippos and whales have barely any hair on their bodies. They also do not have sweat glands. These are both things that can assist them in their aquatic lifestyles.
Do whales have gills?
Whales and dolphins are mammals and breathe air into their lungs, just like we do. They cannot breathe underwater like fish can as they do not have gills. … This allows them to take breaths by exposing just the top of their heads to the air while they are swimming or resting under the water.
How did whales evolve back in the ocean?
Vertebrates evolved in the sea and eventually moved onto land. The ancestors of whales later returned to the sea, taking advantage of its rich food supplies. As early whales adapted to their new marine surroundings, a diversity of species evolved.
Did whales evolve back into water?
Unlike the hippo’s ancestor, whale ancestors moved to the sea and evolved into swimming creatures over a period of about 8 million years.
Do whales have fingers?
Whales have flippers, instead of hands, so they don’t have individual digits like humans do. However whales do have finger bones inside the flippers. These bones are the same structure as the hand bones that humans and most other tetrapods possess.
Do whales hair?
Believe it or not, whales do have hair, although it’s only visible in some species. One of those is the humpback whale. The golfball-sized lumps you see on a humpback’s head each house a hair follicle. Fin, sei, right and bowhead whales also have hair follicles.
Is whale shark a fish?
The whale shark is the biggest fish and shark in the world. These gentle marine giants roam the oceans around the globe, generally alone. However, large numbers of whale sharks often gather in areas with abundant plankton food—making them prime tourist attractions.
Are whales friendly?
From a historical perspective, whales do appear to be non-aggressive. Their relatives, the dolphin’s species, tend to be very friendly and curious towards humans, often displaying a desire to greet and meet people. … They may also show signs of aggression if they are threatened or frightened.
What are similar to whales?
According to molecular evidence, the closest living relatives of whales are, quite surprisingly, the artiodactyls, a group of hoofed mammals that includes deer, cows, sheep, pigs, giraffes, camels and hippos.
