Why is the body of the great white shark not parasitic with a large number of barnacles like whales?

The personal living habits of the great white shark are different from those of the whale Yu, and the things they eat are also different, so the parasitic things on the body are also different, which is the difference between the two animals.

Barnacles are harmful to whales, barnacles have high requirements for speed, and whales can meet the requirements of barnacles, parasitic on the whale's body, and the great white shark is smaller and slower than the whale.

While both great white sharks and whales dominate the water, the body of the great white shark is covered with a layer of stiff scales that prevent barnacles from attaching, while the body of the great white shark is softer and suitable for attachment.

The reason why great white sharks do not have a large number of barnacles parasitized on their bodies like whales is mainly due to the hard scales on their bodies, so it is difficult for barnacles to parasitize on the body of great white sharks.

It's because they evolved differently in different ways, so they will make a big difference in appearance. Just like human beings, they are divided into different countries.

1. What is a barnacle?

Barnacles look more like reefs, and whenever a whale jumps out of the water, many people will find that the whale has a lot of reef-like things attached to its back or head, which is a barnacle. Barnacles are not reefs but a kind of parasitic animal creatures, is a kind of shellfish, many people will get goosebumps after seeing the true face of barnacles, this shellfish creature reproduces very fast, and after attaching to the back of the cetacean, it will use its lower end of the buckle structure to fix itself, just like human teeth to bite the whale's ** tightly, to prevent the whale's dead skin from falling off and throwing the barnacle off. Even a thick-skinned creature like a humpback whale is unbearable after being parasitized by barnacles.

2. Why do barnacles prefer parasitic whales over sharks?

Although whales and sharks are both fish, they are different in nature, whales are mammals and breathe with their lungs, while sharks are fish and breathe with their gills, so sharks cannot stop underwater and need to keep swimming to let the water flow through their gills or they will drown. Because sharks are predators, they swim very fast underwater, which is convenient for catching up with their prey, while parasites cannot parasitize at all in an environment where the current speed is very large, so sharks are basically not parasitized by barnacles, while whales are different, whales generally dive slowly after breathing, whales feed on small fish and shrimp, and swim very slowly, so they are very easy to be parasitized by barnacles.

3. How to get rid of barnacles.

Barnacle parasitism is very difficult to remove, humans can use a hammer and chisel to remove the barnacles on the whale's back, it can be seen that the depth of parasitism, sharks are much more social than whales, even if they are parasitic, they can also find the same kind of help to remove, and whales are lone rangers, they can only jump out of the water and use the parasitic parts to slap the water surface or reef or large ships to hang up the parasitic barnacles, sometimes they will float on the water, let the sun and birds help, but the effect is not good.

Because whales are very large and move on their own, they don't have a companion to help clean up the barnacles. In addition, it's perfect for barnacle growing. Sharks, on the other hand, are social creatures, and their attributes are the opposite of those of whales.

Because the whale** is very rough and swims very slowly, the barnacles are easy to attach to it, and the shark fins are relatively large and swim very fast, **smoother, so there is no barnacle attachment.

Whales are large and move relatively slowly, which is conducive to the growth of barnacles, and sharks move fast and are not easy to attach.

Why are sharks clean and whales have many barnacles? I finally got it today.

Because blue whales are relatively fast swimmers, they don't have barnacles on them. The reason why barnacles live on some whales is actually because these whales swim slowly, and if they swim too fast, they will directly wash away these barnacles during swimming, so it is not conducive to the growth of barnacles. Some whales are too large to swim slowly, making them a good place for barnacles to breed.

Whales are generally quite large, so barnacles will not cause much harm to themselves if they live on them. Barnacles generally live on the rough backs of whales, which can be beneficial to the growth of barnacles. Barnacles are an unsolvable nuisance for whales.

Every time the whale comes out of the water to breathe, it will wash away some barnacles because of the impact, but there is no way to remove the barnacles that are parasitic in more secret places, and the barnacles have a strong reproductive ability, once they grow in one place, then the growth rate is very fast.

Barnacles not only cause harm to whales, but also cause great economic losses to humans. Barnacles generally live on the bottom of the ship, which adds a lot of pressure to the ship, and also causes the ship to directly cause a certain amount of resistance to the ship when it travels on the sea. Although humans use various methods to eliminate barnacles, because barnacles are very reproductive, even humans have no way to deal with barnacles at present.

Whales, on the other hand, are too large and large, and many times even if whales clean up their bodies, but because whales are solitary animals, some places are not cleaned up at all. For dolphins, because they are social animals, when cleaning their bodies, they will have companions to help clean up the places that cannot be cleaned by their bodies, so dolphins generally do not have barnacles on their bodies.

Because barnacles are mollusks that can't stand the ultra-low temperatures of the polar regions, blue whales are mainly distributed in Antarctica, so they are relatively clean physically. Other polar whales are also generally clean, such as narwhals. One of the more barnacles is the humpback whale, a large tropical whale.

Small and medium-sized whales such as killer whales and dolphins are also not very fond of long barnacles.

Because blue whales do not have the food and environment that barnacles need to survive, they do not have barnacles on them.

It may be because the ** of the blue whale is relatively smooth, so the adsorption force is generally poor.

Why are sharks clean and whales have many barnacles? I finally got it today.

In order to get rid of barnacles on their bodies, whales will choose to rush out of the sea frequently. While this can clean up some barnacles, it always treats the symptoms rather than the root cause. Barnacles not only grow fast but also have a hard shell, so it can't get rid of barnacles completely, and some whales hit fishing boats with their bodies because they can't bear the pain of being parasitized by barnacles because sharks swim fast, **smooth, and barnacles may be thrown out before they can parasitize.

They also have a trait that if the environment is not suitable, they will choose to leave on their own initiative. Therefore, in sharks, there is no place to live. This is the fundamental reason why whales breed barnacles in abundance, while great white sharks are clean.

Outwardly, barnacles look like shells, but in fact they are punkylum, and their kinship is closer to crabs and shrimps, belonging to arthropods.

Juvenile barnacles are similar to crabs and shrimps, but they are smaller in size and belong to the zooplankton of the ocean, which are easily devoured by other predators. After a period of childhood development, barnacles will begin to look for fixed attachments. Once attached, they can no longer be separated, so barnacles are more demanding on the environment.

On the one hand, the area is required to be rich in organic matter that can meet their energy needs.

On the other hand, the attachment is rough and uneven, and the place that is too smooth is not conducive to barnacles; In addition, the water flow at the attachment should not be too rapid or too slow. After finding a habitat, barnacles secrete mucus to hold themselves firmly in place with attachments, but if they find that they have chosen the wrong place at this point, they can turn around and leave. Once barnacles are permanently attached to a place, they will live in that place for the rest of their lives.

The reason why barnacles like to parasitize whales is because the swimming speed of whales just meets their attachment needs, and the rough surface of whales is very conducive to barnacle parasitism. However, there are many species of whales, some of which do not have barnacle parasites, such as killer whales. This is because killer whales live in groups, and they can clean each other's barnacles so that the barnacles can be photographed before they are completely parasitic here.

Barnacles really don't attach to them, because the great white shark** is too slippery for barnacles to attach to the great white shark.

No, because great white sharks don't go to places where barnacles are more common to feed, and great white sharks have smooth bodies and barnacles don't have a foothold.

Mainly because of the lump of hard pressing, swimming speed is particularly fast, usually we see killer whales are smooth, but it does not mean that they will not be parasitized, in research shows that the parasite on the tail of the chicken has a barnacle, only by the base of the body gray stone fixed in the neck **, the parasite has a very fast, and can be in the whirlpool of simple plankton.

Barnacles are a kind of crustaceans, and when this creature chooses attachments, it will choose a rough surface, preferably an orange or green solid, so dolphins and sharks do not have this condition.

Because dolphins and sharks live in different environments, they also live in groups, and they will often slap each other's surface for a period of time, and their bodies are very smooth, so there is no way to parasitize.

Barnacle larvae have energetic properties, and the roughness, light and color of the substrate surface in the ocean will affect the selection of barnacle glandular larvae. The dimmer the light that adheres to the substrate, the more willing barnacle larvae will be to attach.

Such a large black creature swimming slowly in the sea is naturally the ideal place for whale lice and barnacle larvae.

Therefore, we can conclude that cetaceans with large size, slow swimming, and darker body color are the most likely to be attached by whale lice and barnacles, so humpback whales, gray whales, and right whales have the most attachments, and other whales have fewer attachments.

Humpback whales, gray whales, and right whales are full of whale lice and barnacles, so why not killer whales?

Killer whales do not meet all but the third one, so whale lice and barnacles do not use it as a host. So it's not because killer whales are ferocious, but because they're smaller, swimmers fast, and move flexibly, so they're not targeted by whale lice and barnacles, and other toothed whales smaller than killer whales naturally have little parasites attached to them.

The situation of sharks is similar to that of toothed whales, and sharks are cartilaginous fishes with specialized shield scales on their bodies, which act as "chain mail" and make it difficult for whale lice and barnacles to attach.

Although sharks do not have whale lice and barnacles, they are troubled by another parasitic fish, that is, the bait, commonly known as sucker fish, which will attach themselves to the shark and "hitchhike" to pick up the shark's food scraps, which makes the sharks living in tropical waters very distressed.

Both whale lice and whale barnacles are mainly parasitic on large cetaceans, and they are large cetaceans that swim slowly, such as bigfin whales, right whales, gray whales, etc. Faster swimmers and small dolphins, such as dolphins, killer whales, fin whales and blue whales, are less common.

Due to the huge size of cetaceans, these whale barnacles do not cause much direct damage to whales, but the indirect effects are not small. Humpback whales have been recorded to have epiphytic barnacles of up to half a ton, which naturally increases the load of the cetacean and increases the resistance of the cetacean to swim. For smaller animals such as sea turtles, the harm caused by a large number of barnacles can be fatal, and the loggerhead turtle pictured below fell into a coma because he was overwhelmed by barnacles!

Eventually, he was washed up on the beach and healed by humans!

Barnacles will cling to stones, whales, and other places where they can survive for their own survival. And in order to be able to firmly attach to the parasite, the body will secrete a very viscous substance, which is a hundred times stronger than the 502 glue we usually use. And the simple attachment has not yet reached the requirements of barnacles, and the lower part of their bodies will be deeply rooted in the **, that is to say, if you want to parasitize on the whale, you have to embed yourself in the slippery ** of the whale.

Parasitizing on whales means that they will face a strong current impact, and this strong current impact will bring them enough water and food, so naturally they cannot miss it. Therefore, after the barnacles are pierced into the whale's **, they will grow siding that are connected to each other, and fix themselves in the whale's **. In this way, piles of white spots will appear on the whale's body, and the whale's body will itch, and a large part of the tickle in the sea is due to the influence of these barnacles.

Barnacles should be no stranger to them, they often attach themselves to whales and turtles, or under the bottom of some boats, so these vehicles that are often active at sea need to clean these things regularly
