What are the similarities between whales and fish?
Fish and whales are both vertebrates, which means they both have backbones. They also live in aquatic environments. Except for a couple of species, whales live only in the ocean water. Fish, however, inhabit both fresh and salt water.
What is the main difference between a fish and a whale as regards respiration?
Answer: Fish have gills which extract oxygen from the water and thus allow it to live underwater its entire life. Whales on the other hand do not have gills but instead have one or two blowholes that connect to its lungs which allow the whale to breathe in air.
How is a whale similar to a fish in adaptation to life in water explain any two features?
Habitat and adaptation | Short Answer Questions (SA) 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.
What’s the difference between fish and whales?
Fish have gills that extract oxygen from the water and allow it to live underwater their entire lives. On the other hand, whales do not have gills but instead have one or two blowholes that connect to their lungs, which allow the whale to breathe in air.
What is the difference between fish and mammal?
Fish – Fish live and breathe under water. They have scaly skin, fins to help them swim and they breathe through gills. Mammals – Mammals are animals that breathe air, grow hair or fur and feed on their mother’s milk as a baby. Reptiles – All reptiles breathe air.
Which is more dangerous between shark and whale?
In the ocean, both the great white shark (Carcharodon carcharias) and the killer whale or orca (Orcinus orca) are fearsome top predators. But of the two massive animals, the killer whale may be the more formidable one, a new study has found.
Is whale an animal or a fish?
Fish have scales. Whales even give birth to live baby whales that will get milk from their mom for food. Fish lay eggs, which must still grow into a baby fish. So whales are indeed mammals and not fish!
How are the respiratory systems of humans and whales similar?
human and a whale. How they are similar How they are different Whales have two passages to their lungs. just like our oral and nasel passages.The. whales lungs are in the same place as the. humans. The human and the whale’s. respiratory system both have a diaphragm. Whales blow holes are like our mouth.
How does a whale breathe through its mouth?
Whales cannot breathe through their mouth because, unlike terrestrial mammals, their digestive system and respiratory system are not connected. The blowhole leads to the nasopharynx, or nasal duct. When the muscles are relaxed, the blowhole is closed by fibrous plugs that prevent water from entering the respiratory system.
Why are whales not connected to the digestive system?
During evolution, blowholes migrated to the top of the head, which facilitates breathing at the water surface. Whales cannot breathe through their mouth because, unlike terrestrial mammals, their digestive system and respiratory system are not connected. The blowhole leads to the nasopharynx, or nasal duct.
What makes a hippopotamus similar to a whale?
Hippopotamuses’ bodies, similarly to whales, are encased in dense fat that is reminiscent of whales’ blubber, which is situated between their muscle and skin.
How does the respiratory system of a whale work?
Since whales are mammals, they must breathe out of the water, like humans. Their respiratory system therefore functions similarly to that of land mammals, but has adaptations specific to their underwater environment. When the animal inhales, air passes through the blowhole, nasal duct, larynx, trachea, and lastly the lungs.

How is the whale’s blowhole similar to a human’s?
A blowhole is essential the nostril of a whale. Similar to a human the whale’s blowhole is attached to their trachea and is connected to the lungs, however unlike humans the whale’s trachea and esophagus are separate, therefore a whale in there would never choke on food like a human might.
