I believe that many people have recently brushed such a creature on major video websites - barnacles, which are attached to the rocks, ships, turtles and whales on the seashore in groups, like brown candy, sticking to it and can't shake it off, and some turtles also die because the barnacles are attached too much. How can such a thing make people so annoying?
what is a barnacles > <h1 class="pgc-h-arrow-right"? </h1>
Barnacles, which sound like the name of a plant, are actually arthropods attached to rough surfaces. Looking at the shape of the barnacles, many people think that it is a shellfish like oysters, but in fact, the close relatives of barnacles are crustaceans such as shrimps and crabs.
Barnacles have a lifespan of about 2-6 years, and before they grow into adults, they also go through three growth states: planktonic, arthropods, and glandular larvae. Barnacles are already free to move when they are arthropods, and after 2-3 weeks of growth, they become glandular larvae. At this time, barnacles will begin to look for a place where they will live for a lifetime.
First the barnacles are towed by the flow of water, or slid with a tentacle to select a suitable place for growth. Where is the right place for barnacles? This requires 3 conditions to be met: first, the water flow is slower; second, the surface is rough; third, the light is darker. When the barnacles find a place where they are more satisfied, they will first use small tentacles to touch the surface, probe and adjust the position. The barnacles then secrete colloids from the antennae, adhere to the surface of the attachment, and finally slowly develop into barnacles into adults, forming a calcareous shell that is permanently attached to it.
how do barnacles <h1 class="pgc-h-arrow-right" > propagate? </h1>
Barnacles are hermaphrodite social animals. Although it is hermaphrodite, it is basically allogeneic fertilization, and there are few cases of self-fertilization, because barnacles are permanently immobile after attachment. Male barnacles will have an extra-long sexual organ, and when breeding, the male barnacles will extend their sexual organs into the nearby female barnacles and gently touch them, and fertilization is successful.
Female barnacles undergo 1-2 months of gestation, and then the mature barnacles are squirted out, following the waves, and the barnacles of the juveniles will begin their new growth cycle. The high incidence of barnacles breeding is from April to October, although the amount of ovulation is related to the individual size of female barnacles and the temperature of the water body.
<h1 class="pgc-h-arrow-right" why do barnacles > choose to attach to turtles and whales over other marine life? </h1>
Most marine life has scales on the surface or has a smooth surface, which is not conducive to barnacles attaching. In addition, marine creatures such as dolphins and sharks are responsive and fast,and barnacles can't catch up with them when they choose attachments when they are young, let alone attach to them.
The whales are attached to barnacles
Some marine creatures are also social creatures, and barnacles are removed with the help of their companions when they choose to attach. Therefore, the best marine life for barnacles to choose from is turtles and whales, as well as marine life such as conchs and oysters.
<h1 class="pgc-h-arrow-right" > barnacles are more harmful? </h1>
The strong attachment of barnacles will seriously affect the speed of marine life and increase the burden of marine life, resulting in cases where marine life cannot prey or avoid predators and cause death. In addition, barnacles can be embedded in the skin of marine life too deeply, which can also cause discomfort to marine life. As a result, we can see that whales often shoot down barnacles attached to them by slapping the surface of the sea and hitting ships to alleviate their pain.
Many people may wonder, why can't you manually remove barnacles for turtles and whales? Animals don't believe in humans, and we can only help clean up turtles when we encounter and catch them by chance. But there are so many sea creatures persecuted by barnacles that we can do only a meager amount of work.
Marine life like whales we can not remove barnacles for them, barnacles are not simply stuck to the skin of whales, as the barnacles grow and the colloid it secretes, barnacles have grown firmly on the skin of whales. If the barnacles are to be removed, they will inevitably cause harm to the whales, which in turn will increase the suffering and mortality of the whales.
In addition to the persecution of marine life, barnacles are also targeted at our ships and coasts in their unique attachments, and barnacles are super fertile and extremely widely distributed. Ships attached to barnacles will have a heavier draft and increase resistance during navigation. Barnacles not only increase the energy consumption of ships, but also increase the danger of ships in the face of natural disasters such as storms.
If barnacles are attached to drains and pipes on the coast, they will also be blocked and drained, so people need to clean these barnacles.
<h1 class="pgc-h-arrow-right" > how to avoid being attached to barnacles? </h1>
Barnacles have no natural enemies, so they grow rampantly, and in order to avoid attaching barnacles, people can say that they have tried their best in this regard. One is to apply toxic paint to the bottom of the boat to prevent barnacles from adhering, but this paint is harmful not only to barnacles, but also to the ocean. Therefore, people often use filters or mechanical removal devices to reduce and remove the attachment of barnacles.
Another way is to eat barnacles, which are called "delicacies from hell" because of their ugly appearance. However, because barnacles have strong adhesion and are not easy to remove, there are not many barnacles on the market, the price is expensive, and the supply exceeds demand.
