Whales are a member of the cetacean family, and as such, despite being wholly water-resident, whales are mammals, not fish.
Is whale a fish or mammal?
Whales are mammals, and they share the characteristics that distinguish that group: they breathe air, are warm-blooded, give live birth, suckle their young on milk, and have hair. They are found throughout the worlds oceans and seas, from the Equator to the polar ice, with the exception of the landlocked Caspian and Aral seas.
Is a fish and a whale the same thing?
Although whales are mammals and fish are not, there are some similarities between the two. Both have fins and a tail, which help them swim and stay upright in the water. However, these similarities are only in appearance. Fish are also covered with a slimy material that helps protect their skin from salt or other chemicals in the water.
Why are whales different from fish?
Whales are not fish because they have lungs and breathe air from above the oceans surface, as opposed to fishs gills, which are almost universally used for breathing. Additionally, whales give birth to live young while most fish lay eggs.
Dolphins are mammals, not fish, and like all mammals, they have warm blooded organs that allow them to breathe. Unlike fish, which breathe through gills, dolphins use their lungs to take in air, necessitating frequent trips to the surface of the water.
Is humpback whale a fish?
Their diet consists mostly of krill and small fish. Unique among large whales, humpbacks use bubbles to catch prey.
|Humpback whale Temporal range: Late Miocene – Recent|
|Genus:||Megaptera Gray, 1846|
Is an octopus a fish?
Invertebrates, which are all animal species excluding those from the subphylum Vertebrata, which includes fish, mammals, reptiles, birds, and amphibians, are characterized by their absence of a backbone. Octopuses fall under this classification.
Are sharks considered fish?
Sharks are a unique species of fish because their bodies are made of cartilage rather than bones like those of other fish. They are aquatic creatures that use their gills to filter oxygen from the water.
Is a Crab a fish?
Crustaceans—and arthropods in general—display many unique aspects to their physiology, as described in A Crab Is Not a Fish: Unique Aspects of the Crustacean Endocrine System and Considerations for Endocrine Toxicology.
Is a starfish a fish?
Sea stars, also known as starfish, are not fish because they lack scales, gills, and fins. Instead of blood, sea water is used to pump nutrients through their bodies via a water vascular system, allowing them to only live in saltwater.
Remember that vertebrates are animals with internal backbones. Fish are aquatic vertebrate animals with gills but without limbs with digits, like fingers or toes. Most fish are streamlined in their general body form. You can talk about one fish or ten fish.
The whale shark is the largest species of fish and can grow to a length of more than 40 feet, just like the blue whale (Balaenoptera musculus), which holds the title of the largest living mammal*. In addition to being the biggest of their kind, both the blue whale and whale shark are filter feeders.
Fish do not have limbs, fingers, toes, fur, or hair, and most of them cannot breathe air, though the lungfish and the snakehead are exceptions.17 September 2021 Fish are not mammals because most of them are not warmblooded, though some shark and species of tuna are exceptions.
Whales are warm-blooded, oxygen-breathing marine mammals that give birth to their young and care for them with milk; fish, on the other hand, are cold-blooded, gill-bearing creatures that lay eggs and frequently abandon their children to fend for themselves after birth.
Whales are mammals, not fish, because they are members of the cetacean family and live entirely in water.
In contrast to fish, which breathe through gills, dolphins breathe air using their lungs, necessitating frequent trips to the surface of the water to catch their breath. Dolphins are mammals, not fish.
Other studies continued to support the evidence, and by the 19th century, the scientific community had largely come to the conclusion that whales were mammals and not fish.
Mammals, such as humans and other land animals, have three inner ear bones, hair, and the ability to breathe air. Female whales also produce milk through their mammary glands and breastfeed their young.
