Why is a mammal not a fish?
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! Fish lay eggs, which must still grow into a baby fish. So whales are indeed mammals and not fish!
Is a shark a fish or a mammal?
Sharks are fish. They live in water, and use their gills to filter oxygen from the water. Sharks are a special type of fish known because their body is made out of cartilage instead of bones like other fish.
Is a fish reptile?
A fish is an animal that lives only in the water, whereas a reptile lives in both land and water. A fish is an aquatic vertebrate that is cold blooded or ectothermic. Some examples of fish are lamprey, sharks, ray fish etc, while lizards, crocodiles, snakes, turtles etc are reptiles.
Is whale a fish or a mammal?
Whales and porpoises are also mammals. There are 75 species of dolphins, whales, and porpoises living in the ocean. They are the only mammals, other than manatees, that spend their entire lives in the water.
Is a penguin a mammal?
Like other birds, penguins have feathers. Penguins are fish, mammals, or amphibians because they live in water, on land, or both. Penguins are birds, even though they spend time on land and in water. Their motion in the water more closely resembles flying than the swimming motion used by other animals.
Can fishes feel pain?
“ Fish do feel pain. It’s likely different from what humans feel, but it is still a kind of pain.” At the anatomical level, fish have neurons known as nociceptors, which detect potential harm, such as high temperatures, intense pressure, and caustic chemicals.
Which fish is biggest in the world?
Just as the blue whale (Balaenoptera musculus) is the largest living mammal*, the whale shark is the largest species of any fish, known to reach more than 40 feet in length. Besides sharing the title of biggest among their kind, the blue whale and whale shark have something else in common. They are both filter feeders.
What color is shark blood?
Since sharks have no bone tissue, they also lack red bone marrow — which, as you point out, produce red blood cells in most vertebrates.
Is Octopus a fish?
An octopus is a mollusk. This is where octopi go down the “mollusk” path and fish down the “chordata” path. To put it in simpler terms, this why an octopus has no bones — no skeleton — it is an invertebrate. A fish has a backbone and a skeleton — it is a vertebrate.
Is a fish a meat?
Fish is the flesh of an animal used for food, and by that definition, it’s meat. However, many religions don’t consider it meat. There are also several important distinctions between fish and other types of meat, especially in terms of their nutritional profiles and potential health benefits.
However, fish scales and reptile scales are not homologous — meaning that they do not arise from the same embryonic tissues. Fish have scales that arise from dermal — bony — tissue and have a somewhat similar composition to bone. These scales form from the epidermis, somewhat like those of snakes and lizards do.
What are the 7 classifications of animals?
There are seven main taxonomic ranks: kingdom, phylum or division, class, order, family, genus, species.
