Micro Post; Hermit Crab

Hermit crab walk on the beach.

Hermit Crab is very unique because it is a creature that resembles a crab but require home (usually empty snail shells) which will be taken here and there to protect the soft parts of their body.

Although resembling crab, hermit crab has its own species and consists of the 1100 species known. Although hermit crabs usually use snail shells to serve as 'home' for their protection, there is also a hermit crab using stones or empty timber as cover material.

Hermit crab body is too soft and become an easy prey for predators.

Hermit crabs inhabit the ocean at various depths, whether on the beach, or even in the shallow waters or deeper. In the tropics there are hermit crabs that live on land (as well as species of land crab and coconut crab). It is nevertheless going into the sea to lay their eggs and hatch their eggs. Besides, most of the hermit crab is out at night to find food.

The biggest problem for a hermit crab is when it’s getting bigger; it needs to get bigger shells to enable it to be comfortable. The narrow shells will cause stunted growth and the possibility of losing their very precious shelter. You may be surprised to see a competition between a hermit crab to grab the empty shells to be used as a shelter. This competition may cause a hermit crab kill each other.

For some larger species, the security measures are also using sea anemones to scare other predators. This is because sea anemones have poisonous tentacles that could have resulted in the deaths of these predators.  Sea anemones will benefit from a hermit crab food waste as one of the rewards of this partnership.

To give you a clearer picture about the fierce competition in the life of a hermit crab to get protection (shell), you may watch the video below for a better understanding.

How Paper Was Invented?

Paper is one of the important inventions that make the development of human knowledge growing even faster. Although the paper used for various purposes, the main usage of paper such as for writing, recording and storing information are the most important usage of paper. Although paper is used by humans but it also had been used by nature (by insects) since millions of years ago.

Insects known as paper wasps or also known as “angkut-angkut” (in Malay) are the real designer of paper. This insect can be found almost all over the world with the number of species up to more than 1,100 species in total. But all these insects build their nests using paper produced using fiber from trees or plants which are then mixed with saliva to form a nest.

Cai Lun, who invented paper making methods.

The uniqueness of this insect was observed by an official Chinese government called Cai Lun (Traditional Chinese : 蔡倫). Cai Lun said to be inspired by his observation of the insects’ paper wasp that build their nests from wood fiber use in about 105 AD. Although the paper production process continues to be improved but retained the original process by collecting a layer of plant fibers suspended in water using a strainer to separate the water before it is dried. It is through this discovery, he was known as one of the key figures with various awards.

Traditional production process of paper.

Paper production technique is expanding to other regions of China to the Middle East and to some parts of Europe. Paper development in the West is through Baghdad and it is known as “bagdatikos”. Since paper is an important material, paper-related industries continue to be developed either in terms of the materials used, as well as its own production process. Even paper recycling technologies are being introduced since 1774 by a jury from German, Justus Claproth.

While paper commonly used to keep a record or to print, it is also used for a variety of other usage such as packaging, boxes, building walls, as handicrafts, food containers, paper and more.

However, reducing paper consumption can safe lots of trees and other plants as a source of fiber (cellulose) where demand for paper continues to grow each year. Today with the advancement of digital technology, the demand for paper had been decreased, but still necessary. In terms of the paper pollution anyway, it's not as bad as the impact of plastic pollution, but if not controlled, it can also lead to negative impacts.

Anyway paper is one of the results that we get from the observations made on nature. For insects "paper wasp" paper has been used by them for millions of years for the purpose of building their nest. Hopefully, we will always be more sensitive to see how to utilize natural resources available in nature itself, but at the same time not damaging it.
