Nature, Nature, Nature...! People talk a lot about nature and the environment, but it's sad; that only talking won't help. We want big houses to live in but as consequence trees are being cut down. Mother nature is giving her gifts to humans from day one. Cotton, wool, silk....for your fabrics, your fashionable clothes and wood for building house, furniture. Also, plants are destroyed, especially flowers are squeezed to dye you pretty looking stylish clothes, bedsheets, decorative items.... and the list goes on. Chemists came into picture and natural dye was replaced with artificial dye and soon plastic or  polymers replaced wood. Things were still not going well. Plastic was not biodegradable and caused pollution. It started accumulating in oceans on land and as a side effect fishes (also other land animals) were suffering. All because of careless humans. Artificial dye has a lot of chemicals as lot of acids and base goes into its manufacturing process. So, as a solution to ...

  BIOLOGY OF CHOCOLATES AND SOME FACTS😉 HISTORY What?? Cocoa (or cacao) seeds were used as currency??😵 Yes, its true. Back in 450 BC cocoa beans were used as currency because the seeds were very valuable and the " Aztecs believed that cacao seeds were the gift of Quetzalcoatl, the god of wisdom." In 1875, Daniel Peter invented milk chocolate taking liquor and adding powdered milk, developed by Henry Nestle, to it. Today chocolate's consumption is increasing continuously and in 2019 it was expected to reach 7.7 metric tones. Mars Wrigley confectionery is the largest producer of chocolates in the world.

  Star"fish" and Sea"horse" Starfish or Sea-stars: Starfish on a beach Travel photo created by awesomecontent - www.freepik.com These organisms are  not actually fishes  as they don't have fins, scales or gills like normals fishes have. Researchers call them  sea-stars  to be more specific with the meaning of its name. Some important characters of sea-stars are interesting but few of them could be stomach-turning. There are more than 20,000 species of starfish and all in a variety of beautiful different colours. This animal is mostly known for its five-feet shape, but some of them have upto 35 to 40 arms. These are Deep sea creatures without any circulatory system or a proper skeletal system like humans. They don't come under the category of fishes, rather, are placed under  invertebrates , in phylum Echinodermata . Mostly exhibit  radial symmetry . Means if cut a starfish from any point in the centre it will always give equal halves. They  don't...

JELLYFISHES Jellyfish??? Are they really fishes?  Group of jellyfish called "smack" Water photo created by jcomp - www.freepik.com No, jellyfish is not actually a fish, as a fish has backbone (kind of) and are vertebrates but jellyfishes are some kind of  dome shaped creatures with tentacles . They are more closely related to sea-anemones and corals. Researchers called them fish before, when proper classification was not possible. They can be called as the oldest animals, around 650 million years old. They look exactly like jelly while floating so the name "jelly". They are found in variety of size and shapes with small microscopic to huge ones.  But....There is something very interesting Jellyfish has very interesting things in store. Could you imagine our body functioning without a brain, heart, lung or any other organ? No you can't. Jellyfish has a fascinating body organisation as it does not have  Brain, Lungs, Bones, Heart etc. But they have teeths and eat...
