What is the difference between a whale and a shark

1. The program is different.

Whale. It is a completely aquatic mammal.

It belongs to the mammalian order; Sharks belong to the class Cartilaginous Fishes.

2. Different ways of reproduction.

The mode of reproduction of whales is viviparous; Sharks reproduce in ovoviparous and ovoviviparous modes.

and viviparous three.

3. The population classification is different.

Whale population classifications include the suborder Baleen Whale and the Toothed Whale suborder; The population classification of sharks is hexagill, porpocryl.

Eight populations of tiger sharks, eusharks, horn sharks, and saw sharks were classified.

1. Different categories.

Sharks are fish. Sharks have been on Earth since 300 million years before the appearance of dinosaurs, more than 500 million years ago, and they have barely changed in nearly 100 million years.

Whales are not fishes, they belong to the phylum Chordates, subphylum Vertebrates, Mammals, and Eumatria, which contain about 98 species of viviparous mammals living in oceans and rivers. There are more than 30 species in China's waters. All species of cetaceans inhabit the ocean, with the exception of a few that live in freshwater.

2. Different body types.

Sharks are ferocious by nature, with a keen sense of smell and the smell of a drop of blood dissolved in millions of gallons of water, so they can quickly locate injured prey from great distances.

Cetaceans are mainly divided into two suborders: baleen whales and toothed whales. Baleen whales are few species, but they are huge, with the smallest known species also measuring more than 6 meters in length, and the largest animal in the world, the blue whale, is also a baleen whale.

3. Different ways to move forward.

Sharks swing their tail fins from side to side to move their bodies forward.

The whale moves forward by swinging its tail fin up and down.

Whales are mammals and sharks are fish.

Whales are viviparous and their larvae are suckling, while sharks are ovoviviparous viviparous or oviparous and can eat fish at birth.

Whales breathe with lungs, with nostrils on the top of the head or anterior maxilla, and sharks breathe with gills, on either side of the head.

The whale's tail fin is horizontal, relying on its upward swing to move forward, the shark is the tail fin longitudinal, relying on the left and right swing of the tail and the coordinated movement of the fins The whale has a neck bone, but it is locked together and cannot move (except for the horned whale, Anglo whale), the shark has no neck bone, the forelimb bones of the whale are limb-like, and the shark has no hard bones in the pectoral fin, and the whale has a placenta, and the shark does not.

Whales are bigger than sharks, but not as fierce as sharks, and there are a few whales that don't eat carnivores, but sharks eat carnivorous things.

Whales are mammals and sharks are fish.

Whales and sharks that you absolutely don't know about.

One eats meat, and the size of the volume.

The differences between sharks and whales are: different subjects, different breeds, different breathing methods, different breeding methods, different ways of advancing, different smoothness, and different body structures.

1. Different subjects: sharks belong to the phylum Chordates, subphylum vertebrates, cartilaginous fishes, and plate-gill subclasses; Whereas, whales belong to the phylum Chordates, subphylum Vertebrates, Mammalia, and Euzozoa.

2. Different species: whales and sharks are different creatures, whales are aquatic mammals, and sharks are cartilaginous fish.

3. Different breathing methods: whales use their lungs to breathe, while sharks use gills to breathe.

4. Different ways of reproduction: most sharks are ovoviviparous, while whales are viviparous.

5. Different ways of advancing: sharks will swing their tails left and right when they advance, and whales will swing their tails up and down when they move forward.

6. Different smoothness: sharks have shield scales on their bodies; Whereas, the whale's ** is smoother and has no scales.

7. Different body structures: sharks do not have hard bones, and their skeletons are made of a substance called cartilage; Whereas, whales have quite a stiff vertebral skeleton.

Although the whale looks like a fish, it is not a fish, but a class of mammals, whales are different from fish, it is viviparous, generally one litter per litter, one litter every two years. The pups are fed by the mother's milk; Fish are oviparous and can lay thousands of eggs at a time, and once hatched, young fish can live independently without lactation.

Sharks belong to the subclass Plategill of the Vertebrate phylum Chondritalia, marine life, a few species enter freshwater, and are a group of medium to large marine fish that swim fast. The endoskeleton of the shark is composed entirely of cartilage, often calcified, but without any true bone tissue, the exoskeleton is not very developed or degenerated, the body is often covered with skin teeth, the teeth are diverse, and there is hard muscle, but the membranous bone never exists, and the brain is seamless. The upper forehead is composed of palatal cartilage, and the lower forehead is composed of Mei's cartilage.

1. The program belongs to different hand reeds. then orange.

Whales are completely aquatic mammals and belong to the mammal order; Sharks belong to the class Cartilaginous Fishes.

2. Different ways of reproduction.

The mode of reproduction of whales is viviparous; There are three types of reproduction in sharks: oviparous, ovoviviparous, and viviparous.

3. The population classification is different.

Whale population classifications include the suborder Baleen Whale and the Toothed Whale suborder; There are 8 population classifications of sharks, including hexigills, porpons, tiger sharks, true sharks, horned sharks, and saw sharks.

Sharks are fish, a large cartilaginous fish; And it is an oviparous or ovoviviparous fish. The whale is not a fish, but a marine mammal, a large sea beast, and the young animals need to eat the milk of the mother animal to grow up.

Whales are mammals and sharks are fish animals. They meet the characteristics of these two types of animals. jrui

Whales and sharks that you absolutely don't know about.

Sharks are fish, whereas whales are mammals. The way of breathing is different: sharks use gills to breathe, while whales use their lungs to breathe.

Sharks and whales are relatively large marine creatures that are both in the upper echelons of the food chain. Generally speaking, the two are more powerful than sharks, because sharks are more ferocious and whales are generally more docile. However, there are also natural predators of sharks, such as killer whales.

When encountering killer whales, sharks generally avoid them.

Whales are important members of the sea beasts, with a fish-like body shape, commonly known as whales. There are many species of whales, there are more than 80 species in the world, and there are more than 30 species in China's waters. They are generally divided into two categories.

There are 11 species in total, called baleen whales, which have no teeth in their mouths; The other type has teeth in the mouth and is called toothed whales, with a total of more than 70 species. Shark teeth are made up of dentine, osteodontic, and enamel-like textures, which evolved from shield scales. The morphology of the tooth is one of the classification basis, there are many styles of shark teeth, there are comb-shaped teeth, special-shaped teeth with different front and rear teeth, three-peaked teeth with 3 tooth tips, multi-peak teeth with more than 5-7 tooth tips, unimodal teeth with l large lateral flattening, stone-paved teeth with many small number of teeth, granular teeth with many fine and small numbers and incisors with wide and flat teeth, a total of 8 styles.

Different food intake, different breathing patterns, different smoothness, different attributes, different ways of progressing, different body structures, and different types.

Sharks belong to a type of fish, specifically they belong to cartilaginous fish. Whales, on the other hand, are not fish, but mammals, although they also have the word "fish" in their name. Due to their different attributes, they are also different in the way they breathe.

As a mammal, whales use their lungs to breathe, while sharks, which are fish, use gills to breathe.

Sharks and whales use different ways of reproduction. Most species of sharks reproduce in an oviparous manner, or ovoviviparous, but whales reproduce in a viviparous manner.

Body structure

Sharks and whales swim in the ocean in a certain way, and they do it in different ways. Sharks swing their tail fins from side to side as they move forward, while whales swing their tail fins up and down to move forward. There is also a difference between the fins of sharks and whales.

Generally whales do not have pectoral and pelvic fins, while sharks have these two fins.

Whale sharks belong to fish, and they breathe with gills. As they breathe, they filter the oxygen from the water and then complete their ventilation. Whales are mammals that use their lungs to breathe, so they need to swim to the surface regularly to breathe.

Sharks do not have hard bones, their skeleton is made of a substance called "cartilage", whereas whales have quite a hard backbone.
