Woodlice - trying to find a balance | Bristol Nature Channel

The life of a woodlouse is ruled by water. Too much or too little will kill them. Join Heather and find out why woodlice are in a constant battle for survival and how they manage to win the fight, almost every time.

They are land living crustaceans which you can find everywhere on Earth other than the North and South poles. However, their evolutionary history has been a difficult story to piece together with little evidence to help scientists figure it. Consequently, this has lead to many different theories. One theory we have explored in our film is that their transition to life on land happened long before the continents drifted apart form one another, around 140 million years ago. This school of thought is based on their worldwide distribution which scientists argue could only have been possible if there was one landmass to travel on. What is clear is that their evolution has been a slow process. It's thought that an ancient ancestor of woodlice was a crustacean that lived at sea. This crustacean just happened to be pre-adapted to life on land meaning that this transition was an easy process without the need to adapt to fresh water first. These pre-adaptations can be seen today and are explored in our film, unravelling their secret to survival when everything, even their own body is against them. Watch our film and find out how woodlice breath, find water, reproduce and other curious behaviours that will make you understand how remarkable these little creatures are. It turns out, sometimes the smallest things in life are the most interesting...
