Dr.Tunnacliffe from Cambridge University shows that rotifers, tiny wheeled animals – can survive extreme hard conditions of being depleted of 90% of their water content, exposure to extreme heat and cold. All that they need to resuscitate themselves is some water.


About 60% of our bodies are filled with water. Should we loose more than 20% of our body’s water content, we face a painful death. That is how important water is for most of the living beings. However, there are some exceptions and rotifers are one among them. These amazing micro creatures which have not had sex for 80 million years are able to handle extreme conditions as shown in the video below. These organisms show that life in the space could be possible.

Was the spider’s web you found very intricate and shiny? Do you know that this could indicate several things about the spider and it’s apprehension of the environment around it?


Animals are known to use conspicuous visual signals too allure prey or deter predators. Using colors, glossiness, ornaments are some of the well known visual signals.

Visual signals used to attract prey could also land up attracting predators and thus involves a trade off based on the situation.
