Every week, we share an interesting fact from the natural world on our social media. These are the things that we tell our children, too. We collected last June’s ‘Did you know?’ and ‘Bee facts’ posts for you, so you can share these with your little one.
Octopi Have Three Hearts
One of them is called ‘systemic heart’ that circulates blood around the body and two branchial hearts that pump it through each of the two gills.
What is more interesting, the systemic heart of the Octopus stops when the animal is swimming. That is why they prefer to crawl as they get tired quickly.
All humans have just one heart.
What does an octopus have more than humans, apart from the hearts?
Spider Silk is Five Times Stronger Than Steel
Spiders use their silk to make webs or other structures to catch prey, or spun cocoons to protect their offspring. It has so many uses for the eight-legged creatures.
A single strand of spider silk is thinner than human hair, but much stronger than steel. One type, spun by Darwin’s Bark spiders, is ten times stronger than Kevlar.
They say a two inches wide rope of spider silk could hold a Boeing 747.
Polar Bears are, in Fact, Black
Polar bears have white fur so that they can easily camouflage themselves in the snow. However, they have short, transparent hair which has no white pigment in it and their skin under it is black. It is because it absorbs energy from the sun and keeps them warm.
There Can Be More Organisms in One Spoon of Soil Than Humans on Earth
Different studies suggest that one spoon of productive soil generally contains between 100 million and 300 billion. They are very tiny indeed and they help to keep the soil healthy for the plants.
